The ROHM reference board for BD7693FJ outputs 400V voltage from the input of 90Vac to 264 Vac. The output current supplies up to 0.5A. The BD7693FJ which is BCM method PFC controller is used. It supplies the system which is suitable for all of products that requires PFC. The PFC adopts boundary conduction mode and switching loss reduction and noise reduction are possible by zero current detection Low total harmonics distortion circuit incorporation
Low power consumption
VCC UVLO function
Error amplifier input short protection
Stable MOSFET gate drive
Soft start
