Overview
The CAT4106YP-T2 is a 6W quad channel DC/DC LED driver produced by onsemi. This integrated multi-channel LED driver and high power DC/DC converter is designed to power backlighting applications up to a total of 6 watts. It features four matched LED strings that can be accurately programmed with uniform drive current set by a single external resistor. Each output channel supports LED string voltages of up to 36V, and the driver automatically adjusts the output voltage to maximize efficiency. The device also includes high resolution dimming control via the EN/PWM logic pin and supports multiple frequencies for precise PWM dimming.
