TPS61098DSER

Overview

The TPS61098DSER is a synchronous boost converter and low-dropout linear regulator (LDO) integrated circuit manufactured by Texas Instruments. It features a dual-output configuration housed in a compact 6-WSON package. The device operates with an input voltage range of 700 mV to 4.5 V. The boost output provides up to 350 mA, while the LDO output delivers up to 200 mA. Quiescent current is specified at 300 nA. The switching frequency is adjustable, and the unit supports operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a synchronous boost converter and a low-dropout linear regulator into a single component for space-constrained designs.
• Supports ultra-low input voltages starting from 700 mV, enabling energy harvesting or battery-powered applications.
• Features adjustable switching frequency to optimize efficiency and external component selection.
• Includes shutdown functionality to minimize power consumption during idle states.

Applications

• Portable consumer electronics requiring efficient power management from low-voltage sources
• Battery-operated devices utilizing single-cell lithium-ion or alkaline batteries
• Wearable technology where minimal footprint and low quiescent current are critical
• IoT sensors and modules powered by energy harvesting systems

Procurement Notes

Verify the suffix 'R' indicates reel packaging when ordering. Confirm the specific output voltage and current ratings match the application requirements, as variants like TPS61098DSET may have different fixed outputs. Ensure compatibility with the 6-WSON thermal pad design for proper heat dissipation. Check RoHS compliance status if required by regional regulations.

Selection Notes

Select this component when both boosted and regulated lower voltages are needed from a single low-voltage source. Compare against standalone regulators to evaluate board space savings. Consider the adjustable frequency feature for noise sensitivity requirements. Verify that the 350 mA boost current meets peak load demands without excessive voltage drop.

Part Context

This part belongs to the TPS61098 family of mixed-signal power management ICs. It complements other Texas Instruments solutions like the TPS61094 bi-directional converter and the TPS610985 variant. The series targets applications demanding high integration and low standby power in small form factors.

Replacement Considerations

TPS61098DSET is a pin-compatible alternative with potentially different fixed output configurations. Evaluate TPS610985DSET for similar topology but verify output specifications. Cross-reference datasheets for thermal performance and electrical characteristics before substitution.
