BF1005 Datasheet (BYD) - ON/OFF Dimming LED Driver IC

BF1005, ON/OFF Dimming LED Driver IC

The BF1005 is a high performance AC/DC on/off LED driver with four-stages dimming.

It uses PFM method to build DCM fly-back power supplies.

It operates in primary-side sensing and regulation while removing the need of secondary feedback circuitry.

The device operates in PFM in CC mode and ON-OFF in
