Product details

Boost regulator for multi-string LED backlight

The TPS61182RTET is a DC DC boost regulator from Texas Instruments designed to drive LED backlight strings. It integrates six current-sink outputs, each rated for 25 mA, with a total output voltage ceiling of 38 V — enough to drive a series string of 8–10 white LEDs depending on their forward voltage. Dimming is handled via a PWM input, allowing the backlight brightness to be controlled by an external PWM signal from a microcontroller or display controller.

Input supply range spans 5 V to 24 V, covering common rails from 5 V USB to 12 V or 24 V industrial buses.

Frequently asked questions

Can TPS61182RTET drive 6 LEDs?

Yes — the device has six independent current-sink outputs, each rated for 25 mA. You can drive up to six separate LED strings, or parallel multiple outputs for higher current per string if the total per-channel current does not exceed 25 mA.
