Product details

Six-channel boost for LED backlight strings

The TPS61180RTETG4 is a step-up DC-DC regulator from Texas Instruments, designed specifically to drive LED backlight arrays in LCD panels and displays. It integrates six current-sink outputs, each rated for 25 mA, with a boost converter capable of delivering up to 38 V to the LED string. Dimming is controlled via a PWM input, allowing precise brightness adjustment without colour shift.
