LED Drivers for LCD Backlights

1ch Boost up Type

White LED Driver for large LCD

BD9411F

General Description

Key Specifications

BD9411F is a high efficiency driver for white LEDs and is

designed for large LCDs. BD9411F has a boost DCDC

converter that employs an array of LEDs as the light

source.

 Operating power supply voltage range: 9.0V to 35.0V

 Oscillator frequency of DCDC: 150kHz (RT=100kΩ)

 Operating Current:

3.3 mA(Typ)

-40°C to +105°C

 Operating temperature range:

BD9411F has some protect functions against fault

conditions, such as over-voltage protection (OVP), over

current limit protection of DCDC (OCP), LED OCP

protection, and over-boost protection (FBMAX).

Therefore it is available for the fail-safe design over a

wide range output voltage.
