LED Drivers for LCD Backlights

2ch Boost up type

White LED Driver for large LCD

BD9416xx Series

1.1 General Description

Key Specifications

BD9416xx Series is a high efficiency driver for white

LEDs and is designed for large LCDs. BD9416xx Series

has a boost DCDC converter that employs an array of

LEDs as the light source.

BD9416xx Series has some protection 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.

 Operating Power Supply Voltage Range:

9.0V to 35.0V

 Oscillator Frequency of DCDC:

150kHz (V_RT=100kΩ)

5.1mA(Typ)

 Operating Current:

 Operating Temperature Range:

-40°C to +105°C
