LED Drivers for LCD Backlights
White LED Driver for large LCD Panels (DCDC Converter Type)
BD9420F
General Description
BD9420F is high efficiency driver for white LED.
This is designed for large sized LCD.
BD9420F is built-in DCDC converter that supply appropriate
voltage for light source.
BD9420F is also built-in protection function for abnormal state such as OVP: over
voltage protection, OCP: over current limit protection of DCDC, SCP: short circuit protection, open detection of LED string.
Thus this is used for conditions of large output
voltage and load conditions.
