PFC Direct current resonance type White LED Driver for Large LCD - BD9412F
BD9412F 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 Low Detection) and LED Open Detection (IS High Detection).
