White LED Driver for large LCD panel - BD9397EFV

BD9397EFV is a high efficiency driver for white LEDs and designed for large LCD panel. This IC is built-in high current drive and high responsibility type 6ch LED drivers and 1ch boost DCDC converter. BD9397EFV has some protect function against fault conditions, such as the over-voltage protection (OVP), LED OPEN and SHORT protection, the over current limit protection of DCDC (OCP). Therefore BD9397EFV 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.
