DN05128/D, 5V/10A Active-Clamp Forward DC-DC Converter Reference Design

DN05128/D, Reference design provides elementary information about an active-clamp forward converter built with the NCP1566 operated in current-mode control. This controller offers many features to build an energy efficient converter with all the needed protections like cycle-by-cycle current limit with a 500-mV sense voltage, over current protection (OPP) for a stable maximum output current limit, over temperature protection with a dedicated NTC pin and a pin to sense an output voltage runaway (loop failure for instance). The controller drives a N-channel MOSFET as with any classical forward converter plus a P-channel for the active-clamp portion
