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.

The synchronous rectified buck converter provides simple, single feedback loop, voltage mode control with fast transient response, from an internal 0.8V temperaturepensated reference voltage.
