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.
