Description
The TDAIO250P200 is a complete 250W power supply evaluation board designed specifically to meet the requirements for an all-in-one computer. The power supply combines a PFC input stage with an LLC DC-DC converter and uses ON Semiconductor control ICs (NCP4810, NCP1654, NCP1397, NCP432) with three Transphorm 600V 290mΩ GaN FETs (TPH3202PS). Designed to switch at 200-250kHz, the compact-size board showcases the GaN devices’ advantage in delivering both small size and high efficiency not possible with existing silicon solutions. With a universal AC input, the all-in-one power supply evaluation board can deliver up to 20A from the 12V output with a peak efficiency of 95.4% from a 230VAC line.
Features
- Power: 250W
- Switching frequency: 200kHz
- Features TPH3202PS
- Easy-to-use platform to investigate GaN
