Description

General part information

BD9483FV Series

BD9483FV is a high efficiency driver for white LEDs and designed for large LCDs. This IC is built-in 2ch boost DCDC converters that employ an array of LEDs as the light source. BD9483FV has some protect function against fault conditions, such as the over-voltage protection (OVP),the over current limit protection of DCDC (OCP), Max duty protection, LED OCP protection. Therefore BD9483FV is available for the fail-safe design over a wide range output voltage.
