TPS61107RGER

Overview

The TPS61107RGER is a dual-output power management IC featuring a synchronous boost converter and a low-dropout linear regulator. It operates from an input voltage range of 0.8V to 3.3V. The primary boost output delivers up to 1.8A at 3.3V, while the secondary LDO provides 500mA at 1.8V. Operating at a fixed switching frequency of 500kHz, it utilizes a 24-VQFN (4x4) package with exposed pad for efficient thermal dissipation.

Feature Summary

• Integrates a high-efficiency synchronous boost converter with a dedicated low-noise LDO in a single compact package.
• Supports wide input voltage ranges suitable for single-cell lithium-ion battery applications.
• Features integrated soft-start functionality to limit inrush current during startup sequences.

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Battery-powered handheld equipment and mobile phones
• Embedded systems utilizing single-cell lithium-ion power sources

Procurement Notes

Verify the specific suffix RGER corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the 24-VQFN footprint matches the target PCB design guidelines. Ensure compliance with RoHS3 standards if environmental regulations apply to the final product deployment.

Selection Notes

Select this component when a combined solution for step-up conversion and stable linear regulation is necessary. It is appropriate for designs where space constraints prohibit separate discrete regulators. Consider the 500kHz switching frequency regarding electromagnetic interference requirements and external inductor selection.

Part Context
