PFC Direct current resonance type White LED Driver for Large LCD_BD94121F (New)

BD94121F is a current resonance type LED Driver with frequency-controlled LED current. It can connect to PFC directly and can use half-bridge structure reducing the number of external components. It incorporates some protection functions against fault conditions such as Over-Voltage Protection, LED Short Detection (IS High Detection) and LED Open Detection (IS Low Detection).
