| Output 1 | 12 V / 20 A |
| IC revision | 1.4 |
Description
Transphorm has designed a complete 250 W power supply evaluation board 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, using ON Semiconductor control ICs (NCP4810, NCP1654, NCP1397, NCP432) together with three Transphorm 600 V GaN high electron mobility transistors (HEMTs).The compact-size board showcases GaN devices’ advantage in delivering both small size and high efficiency not possible with existing silicon solutions. It is designed to switch at 200 kHz in order to shrink the size and maintain high efficiency. With universal AC input, the All-in-One Power Supply Evaluation Board can deliver up to 20 A from the 12 V output with a peak efficiency of 95.4% from a 230 V ac line
