Product details

What this boost LED driver is built for

Two channels, one inductor — the layout win

With two regulated current sinks and a shared boost converter, this part drives two LED strings from a single inductor and a single 1.2 MHz switching stage.

Supply range and single-cell Li-Ion operation

The input supply range runs from 2.5 V minimum to 6 V maximum, which covers a single-cell Li-Ion battery (3.0–4.2 V nominal) cleanly. That makes the TPS61150DRCR a straightforward choice for battery-powered handhelds, tablets, and portable instruments where the backlight needs to stay lit as the battery discharges down to 2.5 V.

PWM dimming and temperature grade

Dimming is handled via a PWM input on each channel, giving the system designer direct brightness control from a microcontroller GPIO or a PWM timer.

Frequently asked questions

Can TPS61150DRCR be used with a single-cell Li-Ion battery?

Yes. The input supply range is 2.5 V to 6 V, which covers the full discharge curve of a single-cell Li-Ion battery (3.0 V to 4.2 V typical, down to 2.5 V cutoff). The boost topology will regulate the LED current even as the battery voltage drops.

Is TPS61150DRCR RoHS compliant?

Yes, the TPS61150DRCR is ROHS3 compliant.
