500kHz
Voltage Mode PWM Controller With Linear Power Regulator
POWER MANAGEMENT com Description
The SC2621 provides the control and protection features necessary for a synchronous buck converter and a linear regulator in high performance graphic card applications.
The SC2621 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 at 500kHz switching frequency with 4V to 16V power rail and as low as 0.
5V output.
The SC2621 is capable to drive a N-type
MOSFET in a linear regulator with as low as 0.
5V output...
