12V Synchronous Buck PWM Controller
EM5301F/G
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.
