SS7529
Synchronous Buck PWM and Linear Power Controller
FEATURE
Controller operates from 5V and 12V Drives two N-channel
MOSFETs for switching buck converter Drives an N-channel
MOSFET on the linear output Fixed 600kHz constant switching frequency Full range 0~100% duty cycle Internal soft start Fast transient response UVP monitoring on both outputs Internal 0.

GENERAL DESCRIPTION
The SS7529 consists of a dual-output power controller and the protection circuits in a single SO-14 package for graphic cards and other applications.
The dual-output power controller provides regulation by driving two N-
MOSFETs in a synchronous rectified buck converter, and one N-
MOSFET in a ...
