TDLED-TPH-ON-DIM-60W-RD
A 60 W Quasi-Resonant Flyback AC-DC LED Dimmable Driver Reference Design using Transphorm SuperGaN Technology
The TDLED-TPH-ON-DIM-60W-RD reference design board describes a 60 W LED dimmable driver with peak efficiency of greater than 93.9% at 120 Vac input, a power density of ~ 30 W/in3.
The power supply uses the ON Semi QRF controller (NCP1342) with dimmable output voltage range between 18 V ~ 24 V; Transphorm's TP65H300G4LSG (650 V, 240 mΩ GaN FET). This battery charger is ideal for applications such as LED dimmable drivers for decorative, cabinet, strip, and high density lighting.
