Using a capacitor whose value is > 1μF on the RT9193 input and the amount of capacitance can be increased without limit. The input capacitor must be located a distance of not more than 0.5 inch from the input pin of the IC and returned to a clean analog ground. Any good quality ceramic or tantalum can be used for this capacitor. The capacitor with larger value and lower ESR (equivalent series resistance) provides better PSRR and line-transient response. The output capacitor must meet both requirements for minimum amount of capacitance and ESR in all LDOs application. The RT9193 is designed specifically to work with low ESR ceramic output capacitor in space-saving and performance consideration. Using a ceramic capacitor whose value is at least 1μF with ESR is > 25m Ω on the RT9193 output ensures stability. The RT9193 still works well with output capacitor of other types due to the wide stable ESR range. Figure 1 shows the curves of allowable ESR range as a function of load current for various output capacitor values. Output capacitor of larger capacitance can reduce noise and improve load transient response, stability, and PSRR. The output capacitor should be located not more than 0.5inch from the V OUT pin of the RT9193 and returned to a clean analog ground.Figure 1Bypass Capacitor and Low NoiseConnecting a 22nF between the BP pin and GND pin significantly reduces noise on the regulator output, it is critical that the capacitor connection between the BP pin and GND pin be direct and PCB traces should be as short as possible. There is a relationship between the bypass capacitor value and the LDO regulator turn on time. DC leakage on this pin can affect the LDO regulator output noise and voltage regulation performance.Enable FunctionThe RT9193 features an LDO regulator enable/disable function. To assure the LDO regulator will switch on, the EN turn on control level must be greater than 1.2 volts.The LDO regulator will go into the shutdown mode when the voltage on the EN pin falls below 0.4 volts. For to protecting the system, the RT9193 have a quick-discharge function. If the enable function is not needed in a specific application, it may be tied to V IN to keep the LDO regulator in a continuously on state.Thermal ConsiderationsThermal protection limits power dissipation in RT9193.When the operation junction temperature exceeds 165°C,the OTP circuit starts the thermal shutdown function turn the pass element off. The pass element turn on again after the junction temperature cools by 30°C.For continue operation, do not exceed absolute maximum operation junction temperature 125°C. The power dissipation definition in device is :P D = (V IN −V OUT ) x I OUT + V IN x I QThe maximum power dissipation depends on the thermal resistance of IC package, PCB layout, the rate of surroundings airflow and temperature difference between junction to ambient. The maximum power dissipation can be calculated by following formula :P D(MAX) = ( T J(MAX) − T A ) /θJAWhere T J(MAX) is the maximum operation junctiontemperature 125°C, T A is the ambient temperature and the θJA is the junction to ambient thermal resistance.Region of Stable C OUT ESR vs. Load Current0.000.010.101.0010.00100.00050100150200250300Load Current (mA)C O U T E S R (Ω)100101RT9193DS9193-09 March 2007For recommended operating conditions specification of RT9193, where T J(MAX) is the maximum junction temperature of the die (125°C) and T A is the maximum ambient temperature. The junction to ambient thermal resistance (θJA is layout dependent) for SOT-23-5 package is 250°C/W, SC-70-5 package is 333°C/W and WDFN-6L 2x2 package is 165°C/W on standard JEDEC 51-3 thermal test board. The maximum power dissipation at T A = 25°C can be calculated by following formula :P D(MAX) = (125°C −25°C) / 333 = 300mW (SC-70-5)P D(MAX) = (125°C −25°C) / 250 = 400mW (SOT-23-5)P D(MAX) = (125°C −25°C) / 165 = 606mW (WDFN-6L 2x2)The maximum power dissipation depends on operating ambient temperature for fixed T J(MAX) and thermal resistance θJA . For RT9193 packages, the Figure 2 of derating curves allows the designer to see the effect of rising ambient temperature on the maximum power allowed.Figure 2.

These devices are available in fixed output voltages of 3.3V, 5V, 12V, 15V, and an adjustable output versions. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed-frequency oscillator. The MIK2576 series offers a high-efficiency replacement for popular three-terminal linear regulators. It substantially reduces the size of the heat sink, and in some cases no heat sink is required. A standard series of inductors optimized for use with the MIK2576 are available from several different manufacturers. This feature greatly simplifies the design of switch-mode power supplies. Other features include a guaranteed ± 4% tolerance on output voltage within specified input voltages and output load conditions, and ±10% on the oscillator frequency. External shutdown is included, featuring 50µA (typical) standby current. The output switch includes cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions.Note: The MIK2576HV is not produced yet.Features• 3.3V, 5V, 12V, 15V, and adjustable output versions •Adjustable version output voltage range• 1.23V to 37V (57V for HV version) ± 4% max over line and load conditions•Guaranteed 3A output current•Wide input voltage range, 40V up to 60V for HV version•Requires only 4 external components•52 kHz fixed frequency oscillator•TTL shutdown capability, low power standby mode •High efficiency•Uses readily available standard inductors •Thermal shutdown and current limit protection Applications•Simple high-efficiency step-down (buck) regulator •Efficient pre-regulator for linear regulators•On-card switching regulators•Positive to negative converter (Buck-Boost)Typical application Figure 1.(Fixed Output Voltage Versions) 7V - 40V(60V for HV) UNREGULATEDDC INPUT +5V REGULATED OUTPUT3A+Block DiagramUNREGULATED DC INPUTC IN3.3V, R2 =1.7K 5V, R2 = 3.1K 12V, R2 = 8.84K 15V, R2 =11.3K For ADJ, Version R1 = Open, R2 =0ΩElectrical Characteristics MIK2576-3.3, MIK2576HV-3.3Electrical Characteristics MIK2576-5.0, MIK2576HV-5.0Electrical Characteristics MIK2576-12, MIK2576HV-12Electrical Characteristics MIK2576-15, MIK2576HV-15Electrical Characteristics MIK2576-ADJ, MIK2576HV-ADJAll Output Voltage V ersionsElectrical CharacteristicsSpecifications with standard type face are for T J = 25°C, and those with boldface type apply over full Operating Temperature Range.

Operating Ratings indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits.For guaranteed specifications and test conditions, see the Electrical Characteristics.Note 2: All limits guaranteed at room temperature (standa rd type face) and at temperature extremes (bold type face).Note 3: External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system performance. When the MIK2576/MIK2576HV is used as shown in the Figure 2 test circuit, system performance will be as shown in system parameters section of Electrical Characteristics.Note 4: Output pin sourcing current. No diode, inductor or capacitor connected to output.Note 5: Feedback pin removed from output and connected to 0V.Note 6: Feedback pin removed from output and connected to +12V for the Adjustable, 3.3V, and 5V, versions, and +25V for the 12V and 15V versions, to force the output transistor OFF.Note 7: V IN =40V (60V for high voltage version).Note 8: The oscillator frequency reduces to approximately 11 kHz in the event of an output short or an overload which causes the regulated output voltage to drop approximately 40% from the nominal output voltage. This self protections feature lowers the average power dissipation of the IC by lowering the minimum duty cycle from 5% down to approximately 2%.Typical Performance Characteristics (Circuit of Figure 2)Normalized Output VoltageLine RegulationDropout VoltageJUNCTION TEMPERATURE (°C)INPUT VOLTAGE (V)JUNCTION TEMPERATURE (°C)StandbyQuiescent Current Quiescent CurrentCurrent LimitJUNCTION TEMPERATURE (°C) INPUT VOLTAGE (V) JUNCTION TEMPERATURE (°C)Switch SaturationVoltageEfficiencyOscilator FrequencySWITCH C URRENT (A) INPUT VOLTAGE (V) JUNCTION TEMPERATURE (°C)Minimum Operating VoltageQuiescent Currentvs Duty CycleFeedback Voltage vs Duty CycleJUNCTION TEMPERATURE (°C)DUTY CYCLE (%)DUTY CYCLE (%)I L OA D = 200mA15V OUT5VI L OA D = 3AI L OA D = 200mAAdjustable Version OnlyV IN = 7VV IN = 40V I LOAD = 500mAAdjustable Version OnlyI LOAD = 50 0mAV IN = 40VV IN = 7VMaximum Power Dissipation (TO-263)Feedback Pin CurrentAMBIENT TEMPERATURE (°C)JUNCTION TEMPERATURE (°C)Switching Waveforms Load TransientAOutput Voltage ChangeC Load CurrentD5s/div100V OUT =15VA: Output Pin Voltage, 50V/div B: Output Pin Current, 2A/div C: Inductor Current, 2A/divD: Output Ripple Voltage, 50mV/div, AC-CoupledHorizontal Time Base: 5µs/divBL O A DTest Circuit and Layout GuidelinesAs in any switching regulator, layout is very important. 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.Fixed Output Voltage Versions (Figure 2a)V INUNREGULATED DC INPUT+V IN1+ G 1N 00DFFEEDBACK4OUTPUT25 L1 100 H +MBR360C OUT 1000V OUTC IN — 100µF, 75V, Aluminum Electrolytic C OUT —1000µF, 25V, Aluminum Electrolytic D1 — Schottky, MBR360L 1 — 100µH, Pulse Eng.
