TPS610985DSET

Overview

The TPS610985DSET is a dual-output power management integrated circuit from Texas Instruments, combining a synchronous boost converter and a low-dropout linear regulator. It operates within an input voltage range of 0.7 V to 4.5 V. The first output provides a fixed 3 V at up to 350 mA via the boost topology. The second output delivers a fixed 3 V at up to 200 mA using the LDO topology. The device is housed in a compact 6-WSON package measuring 1.5 x 1.5 mm. It supports surface-mount installation and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates a synchronous boost converter and a linear regulator for dual independent outputs
• Enables operation from ultra-low input voltages starting at 0.7 V
• Provides fixed 3 V outputs with distinct current capabilities for each channel
• Utilizes a small footprint 6-WSON package suitable for space-constrained designs

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Battery-powered systems utilizing single-cell lithium-ion or lithium-polymer sources
• Wearable technology with strict size and power efficiency constraints
• IoT sensors and modules needing stable 3 V logic and analog supplies

Procurement Notes

Verify the specific suffix DSET corresponds to the required tape-and-reel packaging configuration when ordering. Confirm that the 6-WSON thermal pad requirements align with your PCB layout guidelines. Ensure the selected variant meets the necessary RoHS compliance standards for your region. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability. Check for any specific handling instructions related to moisture sensitivity levels during storage and reflow soldering processes.

Selection Notes

Choose this component when a design requires both boosted and regulated voltages from a single low-voltage source. It is suitable for applications where space is limited due to its small package size. Consider the combined current limits of both outputs to ensure they meet the total system load requirements. Evaluate the input voltage range against the minimum battery discharge voltage of the target application. Verify that the fixed 3 V outputs match the supply needs of the downstream components without requiring external adjustment resistors.

Part Context

This device belongs to the TPS61098x series of power management ICs designed for portable electronics. It complements other single-output boost converters by offering integrated dual-rail functionality. The series targets markets demanding high integration and minimal external component counts. It shares architectural similarities with other Texas Instruments PMICs focused on low-power mobile applications.

Replacement Considerations

Direct substitutes include other TPS61098x variants such as TPS61098DSET, which offers different output configurations. Verify pin compatibility and electrical specifications before swapping parts. Consult the official datasheet for detailed cross-reference information and alternative part numbers.
