TPS61107PWR

Overview

The TPS61107PWR is a dual-output power management IC featuring a synchronous boost converter and an integrated low-dropout regulator (LDO). It operates from an input voltage range of 0.8V to 3.3V. The boost section provides a fixed 3.3V output with up to 1.8A current capability, while the LDO delivers a fixed 1.8V output at 500mA. Designed for space-constrained applications, it utilizes a 24-pin VQFN package measuring 4mm by 4mm and supports switching frequencies up to 500kHz.

Feature Summary

• Integrates a high-efficiency synchronous boost converter with a dedicated linear regulator in a single compact package.
• Provides independent regulated outputs suitable for powering mixed-signal loads requiring different voltage levels.
• Features a small footprint design optimized for portable electronics and battery-powered devices.

Applications

• Portable handheld devices requiring multiple supply rails
• Battery-operated consumer electronics
• Mobile communication modules

Procurement Notes

Verify the specific suffix 'PWR' indicates the tape-and-reel packaging configuration when placing orders. Confirm that the component meets RoHS compliance standards required for your manufacturing process. Ensure the ordering quantity aligns with the manufacturer's standard reel size to avoid partial reel handling issues during assembly.

Selection Notes

Select this component when a combined boost and LDO solution is needed to minimize board space. It is appropriate for systems where the input voltage varies but requires stable 3.3V and 1.8V rails. Consider the thermal performance of the 4x4mm QFN package relative to the expected load currents and ambient temperature conditions.

Part Context

This device belongs to Texas Instruments' TPS6110x family of power management solutions. It is designed to replace discrete boost and LDO combinations, simplifying the bill of materials. The part is commonly used in applications where efficiency and size are critical constraints for mobile and portable hardware designs.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family if lead times are critical. Verify that any substitute maintains the same output voltage configurations and current capabilities. Ensure the replacement package matches the existing PCB footprint to avoid redesign efforts.
