LD7129 - Single Synchronous Buck PWM and Linear Power Controller

LD7129 Description

LD7129 8/27/2004 Single Synchronous Buck PWM and Linear Power Controller General .
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 ap.

LD7129 Features

* Controller Operates from 5V and 12V
* Drive Two N-channel MOSFETs for Switching Buck Converter
* Drive a N-channel MOSFET on Linear Output
* Fixed 600KHz Constant Switching Frequency
* Full Range 0~100% Duty-cycle
* Internal Soft-start
* Fast

LD7129 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. In
