The PW2053 is a high-efficiency monoLithic synchronous buck regulator using a constantfrequency, current mode architecture. The device is available in an adjustable version. Supply currentwith no load is 40uA and drops to <1uA in shutdown. The 2.5V to 5.5V input voltage range makesthe PW2053 ideally suited for single Li-Ion battery powered appLications. 100% duty cycle provideslow dropout operation, extending battery Life in portable systems. PWM/PFM mode operationprovides very low output ripple voltage for noise sensitive appLications. Switching frequency isinternally set at 1.2MHz, allowing the use of small surface mount inductors and capacitors. Lowoutput voltages are easily supported with the 0.6V feedback reference voltage
