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.
