TPS61100PWG4

Overview

The TPS61100PWG4 is a dual-output power management IC from Texas Instruments, featuring a synchronous boost converter and a low-dropout linear regulator. It operates with an input voltage range of 800 mV to 3.3 V. The device provides two distinct output voltages: 1.8 V and 3.3 V. The combined maximum output current capability is specified at 270 mA. It utilizes a TSSOP-20 package for surface-mount installation. The component functions within a temperature range of -40°C to +85°C and operates at a switching frequency of 500 kHz.

Feature Summary

• Integrates a synchronous step-up (boost) converter with a linear regulator in a single package
• Supports wide input voltage operation starting from 800 mV
• Provides dual independent outputs for simultaneous power rail generation

Applications

• Portable battery-powered devices requiring multiple voltage rails
• Systems utilizing single-cell lithium-ion or lithium-polymer batteries
• Embedded applications needing compact power management solutions

Procurement Notes

Verify product status carefully as the TPS61100PWG4 is listed as discontinued by major distributors such as Digi-Key and Mouser. Confirm availability through alternative channels or authorized secondary markets if sourcing is required. Ensure that any replacement components meet the same electrical specifications and pin compatibility requirements for your specific design implementation.

Selection Notes

Select this component when designing systems that require both boosted and regulated voltages from a low-input source. It is suitable for applications where space constraints favor integrated solutions over discrete components. Consider the 270 mA total current limit and the specific 1.8 V and 3.3 V output configurations when evaluating suitability for target loads.

Part Context

This part belongs to the TPS6110x series of power management ICs from Texas Instruments. These devices are designed for portable electronics, offering high efficiency and compact footprints. The TPS61100 variant specifically combines boost and LDO technologies to handle varying load requirements efficiently.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, engineers should evaluate equivalent dual-output PMICs from other manufacturers or newer generations within the Texas Instruments portfolio that offer compatible pinouts and electrical characteristics.
