Product details

Dual-output power IC: boost rail plus LDO in one 20-TSSOP

The Texas Instruments TPS61100PW integrates a synchronous boost converter and a linear (LDO) regulator in a single 20-TSSOP package. Input supply range is 0.8 V to 3.3 V, making it suitable for single-cell Li-ion, two-cell alkaline, or 3.3 V regulated bus applications.

500 kHz switching and industrial temperature range

The boost section switches at 500 kHz, a frequency that allows the use of small inductors while keeping switching losses manageable. Surface-mount assembly in a 20-TSSOP footprint with 0.65 mm pitch — a 2-layer board can typically fan out the pins without vias.

Frequently asked questions

Can TPS61100PW be used for both boost and LDO outputs?

Yes.
