초록

In this paper, high density on-board dc/dc converter using multi-layer PCB is proposed. Recently, the communication system wants power supply of open-frame, high density and low profile. So experimental converter was consisted of 3.3V/30A Quarter Brick size DC/DC Converter. To power height limit, coil of transformer, choke and circuits were consisted of multi layer PCB. Besides to improve of efficiency, made secondary synchronous rectifier Mosfet driving circuit. So total efficiency could be improved.
