BD9408FV
1ch Boost up type White LED Driver for large LCD

BD9408FV is a high efficiency driver for white LEDs and it is designed for large LCDs. BD9408FV has a boost DC/DC converter that can supply appropriate voltage to the light source of LEDs series array. BD9408FV has some protect functions against fault conditions, such as over voltage protection(OVP), over current limit protection of DC/DC(OCP), LED OCP protection, and over boost protection(FBMAX). Therefore, it is available for a wide range output voltage and a wide range load current.
