CAT4106

6 W Quad Channel DC/DC

LED Driver with Diagnostics

Description

The CAT4106 is an integrated multi−channel LED driver and high

power DC/DC converter suitable for powering backlighting

applications up to a total of 6 watts. Up to four matched LED strings

can be accurately programmed with uniform drive current set by a

single external resistor. Each output channel is suitable for LED string

voltages of up to 36 V. The driver automatically adjusts the output

voltage to drive the highest forward voltage string with the minimum

headroom voltage maximizing the efficiency.

High resolution dimming control is achieved by the EN/PWM logic

pin which supports multiple frequencies. This ensures precise PWM

dimming control while the device remains fully biased. In addition,

when held at logic low, the device to enter a full shutdown “zero”

current mode.

External programming resistors set the minimum and maximum

voltage limits for the acceptable “window of operation” for LED

strings. Any channel which fails to regulate within the window (Open

or Short LED) is detected and flagged on the FAULT logic output

(active low, open−drain).
