TPS61130PWR

Overview

The TPS61130PWR is a synchronous power management IC featuring an integrated SEPIC converter and a linear regulator. It supports up to 90% efficiency with a 300-mA output current from a 2.5-V input. The device includes an integrated 200-mA reverse voltage protected LDO. It operates within a temperature range of -40°C to 85°C and is housed in a 16-pin TSSOP package.

Feature Summary

• Integrates a synchronous SEPIC converter capable of step-up, step-down, and buck-boost operations for flexible voltage regulation.
• Includes an integrated low-dropout (LDO) regulator with reverse voltage protection to safeguard connected circuitry.
• Designed for high efficiency, achieving up to 90% performance in standard operating conditions.

Applications

• Portable electronic devices requiring efficient multi-output power solutions
• Cascaded converter systems utilizing LDOs for noise-sensitive loads
• Microprocessor power supply circuits

Procurement Notes

Verify the specific suffix 'PWR' confirms the tape-and-reel packaging format and commercial grade temperature rating. Confirm the manufacturer is Texas Instruments to ensure authenticity. Check for RoHS compliance status as per the latest datasheet revision. Ensure the component matches the 16-TSSOP physical dimensions for board compatibility.

Selection Notes

Select this component when a single IC must provide both isolated or non-isolated boost/buck capabilities and a clean LDO output. It is suitable for battery-powered applications where input voltage varies above and below the required output levels. Consider the 300-mA limit for the main converter and 200-mA for the LDO when sizing the power budget.

Part Context

This part belongs to the TPS6113x family of power management ICs from Texas Instruments. These devices are designed to simplify power architecture by combining switching regulators and linear regulators into a single compact solution. The family targets applications needing multiple voltage rails from a single source.
