PW5410BGENERAL DESCRIPTIONThe PW5410B is a low noise, constant frequency (1.2MHz) switched capacitor voltage doubler. It produces a regulated output voltage from 1.8V to 5V input with up to 100mA of output current. Low external parts count (one flying capacitor and two small bypass capacitors at VIN and VOUT) make the PW5410B ideally suited for small, battery-powered applications.The new charge-pump architecture maintains constant switching frequency to no load and reduces both output and input ripple. The PW5410B have thermal shutdown capability and can survive a continuous short circuit from VOUT to GND. Built-in soft-start circuitry prevents excessive inrush current during start-up.FEATURES● Fixed 3.3V±4% Output ● VIN Range: 1.8V ~ 5V● Output Current: up to 250mA (VIN=3V) ● Low Noise Constant Frequency Operation ● Shutdown Current: <1μA ● Short-Circuit Protection ● Soft-start ● No Inductors●Available in Low Profile 6-Lead SOT-23 PackageAPPLICATIONS● White LED Backlighting● Li-Ion Battery Backup Supplies ● Local 3V to 5V Conversion ● Smart Card Readers●PCMCIA Local 5V SuppliesTYPICAL APPLICATION CIRCUITPW5410BRegulated 3.3V OutputParameter VALUE UnitInput Supply Voltage -0.3V ~ 6VEN Pin Voltage -0.3V ~ 6VOutput Voltage -0.3V ~ 3.5VOutput Current 300 mAOperating Temperature Range (Note 2)) -40℃ ~ +85 °CMaximum Junction Temperature +150 °CStorage Temperature Range -65℃ ~ +125°CLead Temperature (Soldering, 10 sec.) +265 °CNote 1: Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device. Exposure to absolute maximum rating conditions for extended periods may remain possibility to affect device reliability.Note 2: The PW5410B is guaranteed to meet performance specifications from 0℃ to 70℃. Specifications over the –40℃ to 85℃ operating temperature range are assured by design, characterization and correlation with statistical process controls.ELECTRICAL CHARACTERISTICS(Operating Conditions: TA = 25℃, VIN = 3.6V, VEN = VIN, CIN = COUT = 2.2μF, unless otherwise noted.)

Regulation is achieved by sensing the output voltage through an internal resistor divider and modulating the charge pump output current based on the error signal. A 2-phase nonoverlapping clock activates the charge pump switches. The flying capacitor is charged from VIN on the first phase of the clock. On the second phase of the clock it is stacked in series with VIN and connected to VOUT. This sequence of charging and discharging the flying capacitor continues at a free running frequency of 1.2MHz (typ).In shutdown mode all circuitry is turned off and the PW5410B draw only leakage current from the VIN supply. Furthermore, VOUT is disconnected from VIN. The EN pin is a CMOS input with a threshold voltage of approximately 0.8V. The PW5410B is in shutdown when a logic low is applied to the EN pin. Since the EN pin is high impedance CMOS input it should never be allowed to float. To ensure that its state is defined it must always be driven with a valid logic level.Short-Circuit ProtectionThe PW5410B have built-in short-circuit current limiting. At short-circuit condition, it will automatically limit the output current to approximately 300mA.Soft-StartThe PW5410B have built-in soft-start circuitry to prevent excessive current flow at VIN during start-up. The soft-start time is preprogrammed to approximately 2.5ms, so the start-up current will be primarily dependent upon the output capacitor.VIN, VOUT Capacitor SelectionThe style and value of capacitors used with the PW5410B determine several important parameters such as regulator control loop stability, output ripple, charge pump strength and minimum start-up time. To reduce noise and ripple, it is recommended that low ESR (<0.1Ω) ceramic capacitors be used for both CIN and COUT. These capacitors should be 2.2μF or greater. Tantalum and aluminum capacitors are not recommended because of their high ESR.Flying Capacitor SelectionWarning: A polarized capacitor such as tantalum or aluminum should never be used for the flying capacitor since its voltage can reverse upon start-up of the PW5410B. Low ESR ceramic capacitors should always be used for the flying capacitor. The flying capacitor controls the strength of the charge pump. In order to achieve the rated output current it is necessary to have at least 2.2μF of capacitance for the flying capacitor.SOT23-6LSymbolDimensions In Millimeters Dimensions In Inches MinMaxMinMaxA 1.050 1.250 0.041 0.049 A1 0.000 0.100 0.000 0.004 A2 1.0501.1500.041 0.045b 0.300 0.500 0.012 0.020c 0.100 0.200 0.004 0.008 D 2.820 3.020 0.111 0.119 E 1.500 1.700 0.059 0.067 E1 2.6502.9500.104 0.116e 0.950(BSC) 0.037(BSC)e1 1.800 2.000 0.071 0.079 L 0.300 0.600 0.012 0.024θ 0°8°0°8°。
