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 0.8V reference voltage.
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 linear configuration.
