The TPAIO-TPH-PFLLC-CCCV-300W-RD is an open frame universal input line voltage AC-DC battery charger reference design with an output power level of 300 W. This design is composed of two power stages, the first being the PFC (AC to DC) and the second being the LLC (DC to DC). Its peak efficiency is greater than 95% at 264 Vac input.
The power supply uses the ON Semi PFC controller (NCP1654) at the first stage and LLC controller (NCP1399) at the second stage; Transphorm's 3x TP65H070G4PS (650 V, 72 mΩ GaN FET). This battery charger is ideal for applications such as LED dimmable drivers, gaming devices, fast charging, etc.
