Overview
LD7129 8/27/2004 Single Synchronous Buck PWM and Linear Power Controller 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.
Internal 0.
8V temperature-compensated reference voltage.
A fixed 600KHz frequency oscillator reduces design complexity, while balancing typical app...
