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

Key Specification
Operating power supply voltage range:11.0V to 35.0V 
Oscillator frequency:  150kHz (RT=100kΩ)
Operating Current:  3mA (typ.)
Operating temperature range:  -40°C to +85°C
