BD9412F

Datasheet PFC Direct current resonance type White LED Driver for Large LCD BD9412F General Description 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 High Detection) and LED Open Detection (IS Low Detection). Features  20V High Rating Process  1 Channel Push-pull Control  Current and Voltage Feedback by Driving Frequency  Adjustable Soft Start  Adjustable Timer Latch  Under-Voltage Detection for IC’s Power Line  Output Over-Voltage Protection  Output Error Signal from FAIL Terminal  Shift to Save Mode by STB Terminal  Burst Control by External PWM Signal  Analog Dimming by External DC Signal  Conversion Function from Pulse to DC Key Specifications  Operating Power Supply Vo...
