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
