REFACDC047 - Reference Design
With GaN HEMT, Power Factor Correction, 240W 400V BM3G007MUV Reference Board
The BM3G007MUV-EVK-002 reference board outputs 400 V voltage from the input of 90 Vac to 264 Vac. The output current supplies up to 0.6 A.BM3G007MUV has a built-in GaN HEMT (650V 70 mΩ), driver and protection circuit. By using this GaN Power Stage, we achieved a maximum efficiency of 97.8%.
- The BD7695FJ which is BCM method PFC controller IC is used.
- The BD7695FJ supplies the system which is suitable for all of products that requires PFC.
- BCM is used for PFC part, and Zero Current Detection reduces both switching loss and noise.
- THD is 8.4 % typical.
