TPS61107PW

Overview

The TPS61107PW is a synchronous boost converter with an integrated low-dropout regulator (LDO), manufactured by Texas Instruments. It operates within an input voltage range of 0.8V to 3.3V and features a switching frequency of 500kHz. The primary boost output delivers up to 1.8A at 3.3V, while the secondary LDO provides 500mA at 1.8V. Housed in a 24-VQFN package measuring 4x4mm, it supports surface-mount installation and functions across a temperature range of -40°C to 85°C.

Feature Summary

• Integrates a synchronous boost converter and a linear regulator for dual-output power generation
• Supports wide input voltage operation starting from 0.8V
• Features high-efficiency synchronous rectification for the boost stage

Applications

• Portable electronic devices requiring multiple voltage rails
• Battery-powered systems needing efficient step-up conversion
• Embedded applications utilizing single-cell lithium-ion or LiPo batteries

Procurement Notes

Verify the specific suffix 'PW' against the manufacturer's official documentation to confirm the exact package type and tape-and-reel specifications. Ensure that the ordering information matches the required thermal performance and pin configuration for your PCB layout. Cross-reference the datasheet revision history to confirm component availability and any potential design changes.

Selection Notes

Select this component when a compact solution is needed for generating both boosted and regulated voltages from a low-voltage source. Consider the 24-VQFN footprint constraints and thermal dissipation requirements for the 1.8A boost output. Evaluate the 500kHz switching frequency against electromagnetic interference (EMI) constraints in the target application environment.

Part Context
