Rapidly switching currents associated with wiring inductance generate voltage transients which can cause problems. For minimal inductance and ground loops, the length of the leads indicated by heavy lines should be kept as short as possible. Single-point grounding (as indicated) or ground plane construction should be used for best results. When using the Adjustable version, physically locate the programming resistors near the regulator, to keep the sensitive feedback wiring short.C IN—100 μF, 75V, Aluminum ElectrolyticC OUT— 1000 μF, 25V, Aluminum ElectrolyticD1— Schottky, MBR360L1—100 μH, Pulse Eng.

Inductor Selection (L1)A. Calculate the inductor Volt • microsecond constant, E • T (V • μs), from the following formula:B. Use the E • T value from the previous formula and match it with the E • T number on the vertical axis of the Inductor Value Selection Guide shown in Figure 27.C. On the horizontal axis, select the maximum load current.D. Identify the inductance region intersected by the E • T value and the maximum load current value, and note the inductor code for that region.E. Identify the inductor value from the inductor code, and select an appropriate inductor from the table shown in Table 2. Part numbers are listed for three inductor manufacturers. The inductor chosen must be rated for operation at the LM2576 switching frequency (52 kHz) and for a current rating of 1.15 × I LOAD. For additional inductor information, see INDUCTOR SELECTION. 2. Inductor Selection (L1)A. Calculate E • T (V •μs)B. E • T = 115 V •μsC. I LOAD(Max) = 3AD. Inductance Region = H150E. Inductor Value = 150 μH Choose from AIE part #415-0936Pulse Engineering part #PE-531115, or Renco part #RL2445.3. Output Capacitor Selection (C OUT)A. The value of the output capacitor together with the inductor defines the dominate pole-pair of the switching regulator loop. For stable operation, the capacitor must satisfy the following requirement:The above formula yields capacitor values between 10 μF and 2200 μF that will satisfy the loop requirements for stable operation. But to achieve an acceptable output ripple voltage, (approximately 1% of the output voltage) and transient response, the output capacitor may need to be several times larger than the above formula yields.B. The capacitor's voltage rating should be at last 1.5 times greater than the output voltage. For a 10V regulator, a rating of at least 15V or more is recommended. Higher voltage electrolytic capacitors generally have lower ESR numbers, and for this reason it may be necessary to select a capacitor rate for a higher voltage than would normally be needed. 3. Output Capacitor Selection (C OUT)However, for acceptable output ripple voltage select C OUT≥ 680 μFC OUT= 680 μF electrolytic capacitorTo further simplify the buck regulator design procedure, TI is making available computer design software to be used with the SIMPLE SWITCHER line of switching regulators. Switchers Made Simple (Version 3.3) is available on a (3½″) diskette for IBM compatible computers from a TI office in your area.Table 1. Diode Selection GuideTable 2.

Box 12235, San Diego, CA 92112.(3) Renco Electronics Incorporated, (516) 586-5566, 60 Jeffryn Blvd. East, Deer Park, NY 11729.INPUT CAPACITOR (C IN ) APPLICATION HINTSTo maintain stability, the regulator input pin must be bypassed with at least a 100 μF electrolytic capacitor. The capacitor's leads must be kept short, and located near the regulator.If the operating temperature range includes temperatures below −25°C, the input capacitor value may need to be larger. With most electrolytic capacitors, the capacitance value decreases and the ESR increases with lower temperatures and age. Paralleling a ceramic or solid tantalum capacitor will increase the regulator stability at cold temperatures. For maximum capacitor operating lifetime, the capacitor's RMS ripple current rating should be greater thanINDUCTOR SELECTION(1) All switching regulators have two basic modes of operation: continuous and discontinuous. The difference between the two types relates to the inductor current, whether it is flowing continuously, or if it drops to zero for a period of time in the normal switching cycle. Each mode has distinctively different operating characteristics, which can affect the regulator performance and requirements.The LM2576 (or any of the SIMPLE SWITCHER family) can be used for both continuous and discontinuous modes of operation.The inductor value selection guides in Figure 23 through Figure 27 were designed for buck regulator designs of the continuous inductor current type. When using inductor values shown in the inductor selection guide, the peak-to-peak inductor ripple current will be approximately 20% to 30% of the maximum DC current. With relatively heavy load currents, the circuit operates in the continuous mode (inductor current always flowing), but under light load conditions, the circuit will be forced to the discontinuous mode (inductor current falls to zero for a period of time). This discontinuous mode of operation is perfectly acceptable. For light loads (less than approximately 300 mA) it may be desirable to operate the regulator in the discontinuous mode, primarily because of the lower inductor values required for the discontinuous mode.The selection guide chooses inductor values suitable for continuous mode operation, but if the inductor value chosen is prohibitively high, the designer should investigate the possibility of discontinuous operation. The computer design software Switchers Made Simple will provide all component values for discontinuous (as well as continuous) mode of operation.Inductors are available in different styles such as pot core, toriod, E-frame, bobbin core, and so on, as well as different core materials, such as ferrites and powdered iron. The least expensive, the bobbin core type, consists of wire wrapped on a ferrite rod core. This type of construction makes for an inexpensive inductor, but since the magnetic flux is not completely contained within the core, it generates more electromagnetic interference (EMI). This EMI can cause problems in sensitive circuits, or can give incorrect scope readings because of induced voltages in the scope probe.The inductors listed in the selection chart include ferrite pot core construction for AIE, powdered iron toroid for Pulse Engineering, and ferrite bobbin core for Renco.An inductor should not be operated beyond its maximum rated current because it may saturate. When an inductor begins to saturate, the inductance decreases rapidly and the inductor begins to look mainly resistive (the DC resistance of the winding). This will cause the switch current to rise very rapidly. Different inductor types have different saturation characteristics, and this should be kept in mind when selecting an inductor.The inductor manufacturer's data sheets include current and energy limits to avoid inductorsaturation.INDUCTOR RIPPLE CURRENTWhen the switcher is operating in the continuous mode, the inductor current waveform ranges from a triangular to a sawtooth type of waveform (depending on the input voltage). For a given input voltage and output voltage, the peak-to-peak amplitude of this inductor current waveform remains constant. As the load current rises or falls, the entire sawtooth current waveform also rises or falls. The average DC value of this waveform is equal to the DC load current (in the buck regulator configuration).If the load current drops to a low enough level, the bottom of the sawtooth current waveform will reach zero, and the switcher will change to a discontinuous mode of operation. This is a perfectly acceptable mode of operation. Any buck switching regulator (no matter how large the inductor value is) will be forced to run discontinuous if the load current is light enough.OUTPUT CAPACITORAn output capacitor is required to filter the output voltage and is needed for loop stability. The capacitor should be located near the LM2576 using short pc board traces. Standard aluminum electrolytics are usually adequate, but low ESR types are recommended for low output ripple voltage and good stability. The ESR of a capacitor depends on many factors, some which are: the value, the voltage rating, physical size and the type of construction. In general, low value or low voltage (less than 12V) electrolytic capacitors usually have higher ESR numbers.The amount of output ripple voltage is primarily a function of the ESR (Equivalent Series Resistance) of the output capacitor and the amplitude of the inductor ripple current (ΔI IND). See INDUCTOR RIPPLE CURRENT.The lower capacitor values (220 μF–1000 μF) will allow typically 50 mV to 150 mV of o utput ripple voltage, while larger-value capacitors will reduce the ripple to approximately 20 mV to 50 mV.Output Ripple Voltage = (ΔI IND) (ESR of C OUT) (2) To further reduce the output ripple voltage, several standard electrolytic capacitors may be paralleled, or a higher-grade capacitor may be used. Such capacitors are often called “high-frequency,” “low-inductance,” or “low-ESR.” These will reduce the output ripple to 10 mV or 20 mV. However, when operating in the continuous mode, reducing the ESR below 0.03Ω can cause instability in the regulator.Tantalum capacitors can have a very low ESR, and should be carefully evaluated if it is the only output capacitor. Because of their good low temperature characteristics, a tantalum can be used in parallel with aluminum electrolytics, with the tantalum making up 10% or 20% of the total capacitance.The capacitor's ripple current rating at 52 kHz should be at least 50% higher than the peak-to-peak inductor ripple current.CATCH DIODEBuck regulators require a diode to provide a return path for the inductor current when the switch is off. This diode should be located close to the LM2576 using short leads and short printed circuit traces.Because of their fast switching speed and low forward voltage drop, Schottky diodes provide the best efficiency, especially in low output voltage switching regulators (less than 5V). Fast-Recovery, High-Efficiency, or Ultra-Fast Recovery diodes are also suitable, but some types with an abrupt turn-off characteristic may cause instability and EMI problems. A fast-recovery diode with soft recovery characteristics is a better choice. Standard 60 Hz diodes (e.g., 1N4001 or 1N5400, and so on) are also not suitable. See Table 1 for Schottky and “soft” fast-recovery diode selection guide.OUTPUT VOLTAGE RIPPLE AND TRANSIENTSThe output voltage of a switching power supply will contain a sawtooth ripple voltage at the switcher frequency, typically about 1% of the output voltage, and may also contain short voltage spikes at the peaks of the sawtooth waveform.The output ripple voltage is due mainly to the inductor sawtooth ripple current multiplied by the ESR of the output capacitor. (See INDUCTOR SELECTION)The voltage spikes are present because of the the fast switching action of the output switch, and the parasitic inductance of the output filter capacitor. To minimize these voltage spikes, special low inductance capacitors can be used, and their lead lengths must be kept short. Wiring inductance, stray capacitance, as well as the scope probe used to evaluate these transients, all contribute to the amplitude of these spikes.An additional small LC filter (20 μH & 100 μF) can be added to the output (as shown in Figure 33) to further reduce the amount of output ripple and transients. A 10 ×reduction in output ripple voltage and transients is possible with this filter.FEEDBACK CONNECTIONThe LM2576 (fixed voltage versions) feedback pin must be wired to the output voltage point of the switching power supply. When using the adjustable version, physically locate both output voltage programming resistors near the LM2576 to avoid picking up unw anted noise. Avoid using resistors greater than 100 kΩ because of the increased chance of noise pickup.ON /OFF INPUTFor normal operation, the ON /OFF pin should be grounded or driven with a low-level TTL voltage (typically below 1.6V). To put the regulator into standby mode, drive this pin with a high-level TTL or CMOS signal. The ON /OFF pin can be safely pulled up to +V IN without a resistor in series with it. The ON /OFF pin should not be left open.GROUNDINGTo maintain output voltage stability, the power ground connections must be low-impedance (see Figure 21 and Figure 22). For the 5-lead TO-220 and DDPAK/TO-263 style package, both the tab and pin 3 are ground and either connection may be used, as they are both part of the same copper lead frame.HEAT SINK/THERMAL CONSIDERATIONSIn many cases, only a small heat sink is required to keep the LM2576 junction temperature within the allowed operating range. For each application, to determine whether or not a heat sink will be required, the following must be identified:1. Maximum ambient temperature (in the application).2. Maximum regulator power dissipation (in application).3. Maximum allowed junction temperature (125°C for the LM2576). For a safe, conservative design, atemperature approximately 15°C cooler than the maximum temperatures should be selected.4. LM2576 package thermal resistances θJA and θJC.Total power dissipated by the LM2576 can be estimated as follows:P D = (V IN)(I Q) + (V O/V IN)(I LOAD)(V SAT)where•I Q (quiescent current) and V SAT can be found in TYPICAL PERFORMANCE CHARACTERISTICS shown previously,•V IN is the applied minimum input voltage, V O is the regulated output voltage,•and I LOAD is the load current. (3)The dynamic losses during turn-on and turn-off are negligible if a Schottky type catch diode is used.When no heat sink is used, the junction temperature rise can be determined by the following: ΔT J = (P D) (θJA) (4)To arrive at the actual operating junction temperature, add the junction temperature rise to the maximum ambient temperature.T J= ΔT J + T A(5)If the actual operating junction temperature is greater than the selected safe operating junction temperature determined in step 3, then a heat sink is required.。
