EM5303/A

5V/12V Synchronous Buck PWM Controller

General Description

Applications

EM5303/A is a synchronous rectified PWM

controller operating with 5V or 12V supply voltage.

This device operates at 200/300 kHz and provides

an optimal level of integration to reduce size and

cost of the power supply.
