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
