EM5301F/G

12V Synchronous Buck PWM Controller

General Description

EM5301F/G is a synchronous rectified PWM

controller operating with 12V supply voltage. This

device operates at 160/200 kHz and provides an

optimal level of integration to reduce size and cost

of the power supply.

This part includes internal soft start, over

current protection, under voltage protection, over

voltage protection, and shutdown function. This

part is available in PSOP-8 package.
