White LED Driver for large LCD Panels (DCDC Converter type) - BD9483F

BD9483F 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. BD9483F 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 BD9483F is available for the fail-safe design over a wide range output voltage.
