BD7691FJ

General Description

Key Specifications

BD7691FJ is Power Factor Correction for AC/DC supplies

the system which is suitable for all the products needing

power factor improvement. The PFC adopts boundary

conduction mode (BCM), and switching loss reduction and

noise reduction are possible by Zero Current Detection(ZCD).

ZCD detects by resistance, the auxiliary winding is

unnecessary.
