Product details

Dual-output PMIC for portable and industrial rails

The Texas Instruments TPS61130RSAR packs a step-down/step-up (buck/boost) converter and a separate linear regulator (LDO) into a single 16-VQFN Exposed Pad package. This combination is specified for designs that need a main switched rail plus a clean, low-noise auxiliary supply from a common battery input. The buck/boost output delivers 300 mA over a 2.5V to 5.5V range, while the LDO output provides 320 mA across the same voltage window. Input voltage spans 1.8V to 5.5V, covering single-cell Li-Ion down to the depletion point, two-cell alkaline, or a 3.3V regulated bus.

16-QFN footprint and thermal design

The supplier device package is 16-QFN (4x4); the exposed pad must connect to the system ground for both thermal and electrical return current. Moisture sensitivity level (MSL) is not listed in this record; the reel label should be checked before bake decisions.

For dual-sourcing, a parametric search against the same topology (buck/boost + LDO) and 500 kHz switching frequency would be the next step.

Frequently asked questions

Is TPS61130RSAR RoHS compliant?

The part is listed with a Tape & Reel (TR) / Cut Tape (CT) shipping format, which typically implies RoHS-compliant termination finish. The base product number TPS61130 family is manufactured by TI with a lead-free NiPdAu or matte-tin finish on the QFN package; no separate RoHS certificate is included in this record, but the standard TI RoHS declaration applies.

What are typical applications of TPS61130RSAR?

Typical applications include battery-powered portable devices (smartphones, tablets, handheld instruments) that need a main processor core rail from the buck/boost and a clean analog or I/O supply from the LDO. The industrial temperature range also suits outdoor telecom, factory automation, and medical monitoring equipment where a single Li-Ion cell must generate both a switched and a linear rail.

Does the TPS61130RSAR have an enable pin?

The record does not list an enable pin explicitly, but the topology (buck/boost + LDO) and the 16-pin QFN package typically include an enable input for each output. The datasheet should be consulted for the exact pin assignment and enable threshold voltages.

What is the switching frequency of the TPS61130RSAR?

The switching frequency is 500 kHz. This is a fixed-frequency design, which simplifies EMI filter design and allows the use of small inductors (typically 4.7 µH to 10 µH).
