5V/12V Synchronous Buck PWM Controller
EM5303/A
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.
This part includes internal soft start, internal compensation networks, over current protection, under
voltage protection, and shutdown function. This part is available in PSOP-8 package.
