Product details

Six-string boost driver for LCD backlight panels

It integrates six current-sink outputs, each rated for 25 mA, and delivers a regulated output voltage up to 38 V to handle series-connected LEDs. Dimming is controlled via a PWM input, allowing the backlight brightness to be adjusted without audible noise from the inductor.

Input supply and temperature range for the BOM

The device accepts a supply voltage from 5 V to 24 V, covering common rails in automotive infotainment, industrial HMIs, and portable equipment. Internal switches eliminate the need for an external MOSFET, simplifying the layout and reducing component count.

Frequently asked questions

How many outputs does TPS61182 have?

The TPS61182 provides six regulated current-sink outputs, each rated for 25 mA, for driving multiple LED strings in parallel.

What is the switching frequency of TPS61182?

The switching frequency is fixed at 1.3 MHz, which allows the use of small inductors and ceramic capacitors while keeping switching losses manageable.

Does TPS61182 include internal switches?

Yes, the TPS61182 integrates the switching MOSFET internally, so no external power switch is needed for the boost converter.
