TPS61131PW

Overview

The TPS61131PW is a SEPIC (Single-Ended Primary Inductor Converter) switch-mode power supply IC manufactured by Texas Instruments. It provides a fixed 3.3V output voltage with high conversion efficiency, rated at up to 90%. The device is designed for applications requiring input voltages that may rise above or fall below the desired output level, utilizing the SEPIC topology to handle such variations effectively. It integrates necessary control logic and power switching elements into a single package.

Feature Summary

• Supports SEPIC topology for flexible input-to-output voltage relationships
• Delivers a stable 3.3V regulated output
• Optimized for high energy efficiency in power conversion

Applications

• Portable battery-powered electronics
• Systems with wide input voltage ranges
• General-purpose DC-DC power regulation

Procurement Notes

Verify the complete part number including the suffix 'PW' to ensure the correct HTSSOP package variant is ordered. Confirm that the required output voltage matches the fixed 3.3V specification of this specific component. Check manufacturer documentation for any recent lifecycle status updates or alternative recommendations before finalizing procurement plans.

Selection Notes

Select this component when the application requires a non-inverting buck-boost capability using the SEPIC architecture. It is suitable for designs where the input source voltage can exceed or drop below the target 3.3V rail. Ensure the external inductor and capacitor selections align with the internal switching characteristics defined in the official datasheet for optimal performance.

Part Context

This device belongs to the family of DC/DC switching regulators produced by Texas Instruments. It serves as a specialized power management solution for scenarios demanding efficient voltage translation between varying input sources and a constant output load.
