Overview
Voltage Mode PWM Controller With Linear Power Regulator POWER MANAGEMENT Description The SC2621A provides the control and protection features necessary for a synchronous buck converter and a linear regulator in high performance graphic card applications.
The SC2621A is designed to directly drive the top and bottom MOSFETs of the buck converter.
It uses an internal 8.
2V supply as the gate drive voltage for minimum driver power loss and MOSFET switching loss.
It allows the converter to operate with 4V to 25V power rail and as low as 0.
5V output.
The SC2621A is capable to drive a N-type MOSFET in a linear regulator with as low as 0.
5V output.
The SC2621A features soft-start,...
