Overview

The TPSM83101SIUR is a highly integrated buck-boost power module (uSiP) that delivers up to 1.2A of continuous output current from a 1.6V to 5.5V input range. By integrating the inductor and power MOSFETs into a compact 2.6mm x 2.1mm package, it simplifies PCB layout and minimizes the external component count. This module is designed for point-of-load regulation where space is constrained and a seamless transition between buck and boost modes is required.

Why Choose This Part

The module features a low quiescent current of 8uA and a power-save mode to maintain high efficiency under light load conditions. Its 2MHz fixed-frequency switching and integrated inductor significantly reduce EMI concerns and design complexity compared to discrete solutions. The device also supports a true shutdown function that completely disconnects the load from the input source.

Applications

Battery-Powered Handhelds
Efficiently regulates a variable single-cell Li-Ion or Li-Po battery voltage to a steady 3.3V or 5V rail.
Optical Modules
Provides clean power for SFP or QSFP transceivers requiring precise voltage regulation in a small footprint.
Smart Metering
Supplies power to communication modules that experience high peak current pulses during transmission.
Point-of-Load Regulation
Serves as a compact regulator for localized digital rails in systems with 3.3V or 5V intermediate buses.

Getting Started

Engineers can evaluate this module using the TPSM83101EVM evaluation board to test efficiency and load transients across the 1V to 5.5V output range. Design requires only a few external capacitors and a resistor divider for adjustable output versions. For high-density layouts, ensure the thermal pad is soldered according to TI's recommended land pattern for optimal heat dissipation.
