Overview
Datasheet LED Drivers for LCD Backlights 1ch Boost up type White LED Driver for large LCD BD9413F 1.
1 General Description BD9413F is a high efficiency driver for white LEDs and is designed for large LCDs.
BD9413F has a boost DCDC converter that employs an array of LEDs as the light source.
BD9413F 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.
