Dual Channel Interleaved Synchronous-Rectified
Buck Controller
General Description
Features
The uP3861P is a pact dual-channel synchronous rectified buck controller specifically designed to operate with single 12V supply voltage and to deliver high quality output voltage for high power application. The two channels are operated with 180 degree phase interleaved. The twochannel output voltage has power on sequence set. It adopts external pensated voltage mode control to tightly regulate the feedback voltage to internal 1V reference voltage. The switching frequency is programmable from 50KHz to 400KHz, providing an optimal level of integrating to reduce size and const of...
