5V/12V Synchronous Buck PWM Controller
EM5301
General Description
EM5301 is a synchronous rectified PWM
controller operating with 5V or 12V supply voltage.
This device operates at 200/300/500 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.
