The PMP41130 demonstrates a symmetrical hard- switching full-bridge DC-DC power converter with digital control using the UCD3138064, LMG3100, and LMG2175 devices. This Reference design includes required control functions for a hard-switched full bridge (HSFB) converter. PMP41130 accepts a DC input from 36VDC to 60VDC, and outputs a nominal 48VDC with full output load power 1200W, or full output current 25A. Peak efficiency of 96.7% achieved with 36V input voltage and 600W output condition.
