The PW5200A/ PW5200C 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 s***es power and improves efficiency.
The PW5200A/ 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.
