BD94122F Datasheet - ROHM

BD94122F White LED Driver

BD94122F is a current resonance type LED Driver, which can connect to PFC directly. LED current is controlled by driving output frequency. Because this IC can use half bridge structure, it can reduce the number of external components. BD94122F has some protection functions against fault conditions s.
