PW5200C锂电池升压IC，一级代理商

GENERAL DEscriptION

ThePW5200C is high efficiency synchronous, PWM step-up DC/DC converters optimized to provide a high efficient solution to medium power systems. The devices work with a 1.4MHz fixed frequency switching. These features minimize overall solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. Automatic PWM/PFM mode switching at light load saves power and improves efficiency.

The PW5200C is capable of supplying an output voltage between 2.5V and 5V, the internal synchronous switch is desired to provide high efficiency without Schottky.
