1ch Boost up type White LED Driver for large LCD
BD9411F is a high efficiency driver for white LEDs and is designed for large LCDs. BD9411F has a boost DCDC converter that employs an array of LEDs as the light source. BD9411F has some protect functions against fault conditions, such as over-voltage protection (OVP), over current limit protection of DCDC (OCP), LED OCP protection, and over-boost protection (FBMAX). Therefore it is available for the fail-safe design over a wide range output voltage.
