TPS61100RGER

Overview

The TPS61100RGER is a dual-output power management IC designed for single-cell battery applications. It integrates a synchronous boost DC/DC converter and a low-dropout (LDO) linear regulator within a compact 24-VQFN package. The device operates with an input voltage range of 2.7 V to 5.8 V, supporting lithium-ion or lithium-polymer cells. The boost converter provides high-efficiency step-up conversion, while the LDO offers clean output regulation. This configuration allows for efficient power delivery in portable electronics requiring multiple voltage rails from a single cell source.

Feature Summary

• Integrates a synchronous boost converter and an LDO linear regulator in a single package
• Designed specifically for single-cell battery powered applications
• Provides independent regulated outputs for diverse system requirements

Applications

• Portable medical devices
• Handheld communication equipment
• Industrial handheld instruments

Procurement Notes

Verify component authenticity through authorized Texas Instruments distributors or certified partners. Confirm the specific revision level matches design requirements. Check for moisture sensitivity labeling prior to soldering. Ensure storage conditions comply with JESD-020 standards to prevent package damage. Validate that the 24-VQFN footprint aligns with the target PCB layout specifications.

Selection Notes

Select this component when designing systems powered by a single lithium cell requiring both boosted and regulated lower voltages. Consider the thermal performance of the VQFN package under maximum load conditions. Evaluate the switching frequency compatibility with external passive components. Verify that the combined output current demands do not exceed the device's thermal limits in the intended enclosure environment.
