General Description

The LD7129 consists of the dual-output power controller and the protection circuits in a single SOP-14 packaged chip for the graphic card and other applications.

The dual-output power controller provides the regulation on a synchronous rectified buck converter by driving 2 N-MOSFETs 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.

Key Features
