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 .
