Product details

Dual-rail power IC — buck-boost plus LDO in one 16-TSSOP

The Texas Instruments TPS61132PWRG4 is a dual-output power management IC that integrates a step-down/step-up (buck-boost) converter and a linear (LDO) regulator in a single 16-TSSOP package. It delivers a regulated 3.3 V at 300 mA from the buck-boost channel and 1.5 V at 320 mA from the LDO channel, accepting an input supply from 1.8 V to 7 V.

Switching frequency and temperature range

The 16-TSSOP package and Tape & Reel (TR) format are standard for pick-and-place lines; no MSL bake is expected for a TSSOP body of this size, but confirm the date code on any surplus stock.

Frequently asked questions

Can TPS61132PWRG4 be used for step-up conversion?

Yes, the first output channel is a step-down/step-up (buck-boost) converter, so it can regulate a 3.3 V output from an input voltage that is either above or below 3.3 V.

What is the switching frequency of TPS61132PWRG4?

The switching frequency is 500 kHz. This is a fixed-frequency design — no external sync or frequency-adjust pin.
