1ch Boost up type White LED Driver for large LCD - BD9413F (New)

BD9413F is a high efficiency driver for white LEDs and is designed for large LCDs. BD9413F has a boost DC/DC 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 DC/DC (OCP), LED OCP protection, and Over boost protection (FBMAX). Therefore it is available for the fail-safe design over a wide range output voltage.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
