Product details

Dual-rail power from a single inductor

The Texas Instruments TPS61100PWR integrates a synchronous step-up (boost) converter and a linear LDO regulator in one 20-TSSOP package. Output 2 is the LDO: adjustable from 0.9 V to 3.6 V at 500 mA. The two rails let one IC power both the main load and a lower-voltage analog or logic rail without a second switcher.

500 kHz switching — inductor sizing trade-off

The boost converter switches at 500 kHz.

Temperature range and board environment

The 20-TSSOP body (4.40 mm width) is a surface-mount footprint that reflows without special handling.

Listed as Active on the product status.

Frequently asked questions

What is the difference between TPS61100PWR and TPS61100PW?

The suffix 'R' in TPS61100PWR indicates Tape & Reel packaging for automated pick-and-place assembly. The TPS61100PW variant ships in a tube. The silicon and electrical ratings are identical.
