2010 Microchip Technology 1AN1335 ABSTRACTThis application note provides the digital implementa-tion of a telecom input 36 VDC-76 VDC to output 12 VDC,200W Quarter Brick DC/DC Brick Converter using thePhase-Shifted Full-Bridge (PSFB) topology. This topol-ogy combines the advantages of Pulse-WidthModulation (PWM) control and resonant dsPIC33F GS family series of Digital Signal Con-trollers (DSCs) was introduced by Microchip Technol-ogy Inc., to digitally control Switched Mode PowerConverters. The dsPIC33F GS family of devices con-sists of an architecture that combines the dedicatedDigital Signal Processor (DSP) and a devices support all of the prominent power con-version technologies that are used today in the powersupply addition, the dsPIC33F GS family of devices con-trols the closed loop feedback, circuit protection, faultmanagement and reporting, soft start.
