EM5303A - 5V 12V Synchronous Buck PWM Controller

Download the EM5303A datasheet PDF. This datasheet also covers the EM5303 variant, as both devices belong to the same 5v 12v synchronous buck pwm controller family and are provided as variant models within a single manufacturer datasheet.

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.
