TDTTPLLC-TPH-ON-330W-RD

The TDTTPLLC-TPH-ON-330W-RD AC to DC reference design offers an output power level of 330 W. It is designed with a bridgeless Totem-pole PFC boost converter operating in critical conduction Mode (CrM) and a LLC power stage with secondary side synchronous rectification. The 330 W PSU uses Transphorm’s TP65H070G4LSG and TP65H150G4LSG SuperGaN FETs that are incorporated in the primary side of each power stage. The use of Transphorm GaN FETs results in a highly efficiency and power dense (29.4 W/in3 - open frame) solution.
