TPS61098DSET

Overview

The TPS61098DSET is a dual-output power management IC from Texas Instruments, integrating a synchronous boost converter and a low-dropout linear regulator in a compact 6-WSON package. It operates with an input voltage range of 0.7 V to 4.5 V. The synchronous boost output provides up to 350 mA at 4.3 V, while the LDO delivers 200 mA at 2.2 V. Designed for space-constrained portable applications, it features adjustable switching frequency and ultra-low quiescent current of 300 nA to maximize battery life.

Feature Summary

• Integrates a synchronous boost converter and a low-dropout linear regulator within a single compact package
• Supports very low input voltages starting from 0.7 V for efficient energy harvesting from depleted batteries
• Features adjustable switching frequency to optimize efficiency and minimize external component size
• Includes shutdown functionality to achieve ultra-low standby current consumption

Applications

• Portable consumer electronics requiring multi-rail power supplies
• Battery-powered devices utilizing single-cell lithium-ion or lithium-polymer sources
• Wearable technology and smart home devices with strict space constraints
• IoT sensors and modules needing simultaneous boosted and regulated voltage rails

Procurement Notes

Verify the specific suffix DSET corresponds to the required tape-and-reel packaging configuration. Confirm that the 6-WSON footprint matches your PCB layout guidelines. Ensure compatibility with RoHS3 standards if required by your manufacturing process. Cross-reference the manufacturer part number against authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when design requirements demand both step-up and stable linear regulation from a single low-voltage source. It is suitable for systems where board space is limited and multiple discrete regulators would exceed available area. Consider the thermal performance of the WSON package under maximum load conditions. Evaluate the need for adjustable frequency to meet electromagnetic interference constraints.

Part Context

This device belongs to the TPS61098 family of dual-output power management solutions. It shares architectural similarities with other integrated PMICs designed for mobile applications but offers specific output configurations tailored for mixed-signal systems. The family emphasizes high integration levels to reduce bill-of-materials counts in compact electronic designs.

Replacement Considerations

TPS610985DSET serves as a functional alternative within the same series, offering similar topology with potentially different fixed output voltage settings. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
