TPS61130PW

Overview

The TPS61130PW is a synchronous SEPIC and flyback converter manufactured by Texas Instruments, housed in a 16-TSSOP package. It integrates a 1.1-A power switch and an LDO regulator. The device supports input voltages from one-cell Li-Ion/Li-Polymer or two- to four-cell alkaline batteries. It achieves up to 90% efficiency and provides an adjustable output voltage with a fixed 3.3V/300mA LDO option.

Feature Summary

• Integrates a 1.1-A synchronous power switch for high-efficiency conversion
• Supports both SEPIC and flyback topologies for flexible input/output configurations
• Includes an integrated low-dropout (LDO) regulator for auxiliary power rails

Applications

• Power supply solutions for products powered by one-cell Li-Ion or Li-Polymer batteries
• Systems requiring power from two- to four-cell alkaline battery packs
• Portable electronic devices needing efficient step-up and step-down voltage regulation

Procurement Notes

Verify the specific suffix of the part number to ensure correct packaging and temperature grade. Confirm that the 16-TSSOP package matches your PCB footprint requirements. Check the datasheet for minimum order quantities and lead times associated with the manufacturer's current production status before placing orders.

Selection Notes

Select this component when designing systems with single-cell lithium or multi-cell alkaline inputs requiring wide input voltage ranges. The integrated 1.1-A switch suits moderate load applications. Ensure the chosen topology (SEPIC or flyback) aligns with the required input-to-output voltage relationship and isolation needs.

Part Context

The TPS61130 belongs to the TPS6113x family of synchronous converters. It is designed for portable applications where battery life is critical. The PW suffix indicates a 16-TSSOP surface-mount package. It complements other Texas Instruments power management ICs by offering combined switching and linear regulation capabilities.
