5V/12V Synchronous Buck PWM Controller

EM5303/A

General Description

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.

This part includes internal soft start, internal compensation networks, over current protection, under

voltage protection, and shutdown function. This part is available in PSOP-8 package.
