TPS61100PWR

Overview

The TPS61100PWR is a dual-output switching voltage regulator manufactured by Texas Instruments, housed in a 20-pin TSSOP package. It integrates a boost DC/DC converter and an LDO, designed for single or dual cell applications. The device operates with an input voltage range of 800 mV to 3.3 V. It features adjustable high-efficiency boost conversion alongside a linear regulator output. The component supports an operating temperature range from -40 °C to +125 °C, ensuring reliability in demanding environments.

Feature Summary

• Integrates a dual-output architecture combining a boost DC/DC converter with a linear regulator (LDO) within a single package.
• Supports operation from single-cell to dual-cell battery configurations via a wide input voltage range.
• Provides adjustable high-efficiency boost conversion capabilities optimized for power management efficiency.

Applications

• Power management for portable devices utilizing single-cell lithium-ion batteries
• Dual-rail power supply systems requiring simultaneous boost and linear regulation
• Embedded systems in industrial or automotive environments requiring extended temperature stability

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the tape-and-reel packaging format when ordering. Confirm that the 20-pin TSSOP footprint matches the target PCB layout dimensions. Ensure the design accounts for the thermal dissipation requirements associated with the integrated LDO section under maximum load conditions. Cross-reference the datasheet revision to confirm pinout compatibility with existing reference designs.

Selection Notes

Select this component when a system requires both stepped-up voltage and stable linear regulation from low-voltage sources. It is suitable for applications where board space is limited due to the integrated dual-function design. Consider the input voltage range of 800 mV to 3.3 V against the available energy source. Evaluate the thermal performance of the TSSOP-20 package if high continuous current loads are expected from the linear regulator section.

Part Context

This part belongs to the TPS61100 family of dual-output converters. It is distinct from single-output boost regulators like the TPS61200DRCT. The PWR variant specifically denotes the plastic small-outline package with exposed thermal pad. It serves as a solution for complex power rails in mobile and handheld electronics.

Replacement Considerations

Direct substitutes include other dual-output boost/LDO combinations from Texas Instruments such as the TPS61100PW. Verify pin-to-pin compatibility and electrical specifications before swapping. Single-output alternatives require additional external components to achieve similar functionality.
