TPS610981DSET

Overview

The TPS610981DSET is a synchronous boost converter manufactured by Texas Instruments, designed for low input voltage applications. It operates within an input voltage range of 700 mV to 4.5 V and provides a fixed output voltage between 3.201 V and 3.399 V. The device supports an output current of 500 mA with two outputs. Key electrical specifications include a quiescent current of 300 nA and an adjustable switching frequency. It functions reliably across a temperature range of -40°C to +85°C and is housed in a compact 6-WSON package.

Feature Summary

• Integrates synchronous rectification for high efficiency at low input voltages
• Features ultra-low quiescent current to extend battery life in portable devices
• Includes shutdown functionality for effective power management
• Supports adjustable switching frequency for flexible design optimization

Applications

• Low input voltage power supply systems
• Portable electronic devices requiring efficient step-up conversion
• Battery-powered equipment with strict power consumption constraints

Procurement Notes

Verify the specific output voltage tolerance and pin configuration against the official TPS610981 datasheet before integration. Confirm that the WSON-6 package dimensions match your PCB footprint requirements. Ensure compatibility with the required input voltage range and load conditions specified in the technical documentation.

Selection Notes

Select this component when a fixed ~3.3 V output is required from a low-voltage source. It is suitable for designs needing moderate output current with minimal standby power consumption. Consider the adjustable frequency feature if EMI filtering or synchronization with other system clocks is necessary for the application.

Part Context

This part belongs to the TPS61098x series of low-input synchronous boost converters. It shares architectural similarities with models like the TPS61098 and TPS610985 but differs in fixed output voltage settings. The series targets applications demanding high efficiency in small form factors.

Replacement Considerations

Check the TPS61098DSET and TPS610985DSET for alternative output configurations within the same family. Verify pin-to-pin compatibility and thermal performance before substituting.
