TPS610985DSER

Overview

The TPS610985DSER is a dual-output power management integrated circuit from Texas Instruments, combining a synchronous boost converter and a low-dropout linear regulator. It operates with an input voltage range of 0.7V to 4.5V. The boost output provides 3V at 350mA, while the LDO output delivers 3V at 200mA. Packaged in a compact 6-WSON (1.5x1.5mm) footprint, it supports surface-mount installation. The device functions within a temperature range of -40°C to +85°C and features ultra-low quiescent current for extended battery life in portable applications.

Feature Summary

• Integrates a synchronous boost converter and a linear regulator in a single package
• Enables operation from very low input voltages starting at 0.7V
• Provides independent regulated outputs for simultaneous power rail requirements
• Features ultra-low static current consumption to maximize battery efficiency

Applications

• Portable consumer electronics requiring multiple voltage rails
• Battery-powered devices with space-constrained PCB layouts
• Wearable technology utilizing coin cell or small lithium batteries
• IoT sensors and modules needing efficient step-up regulation

Procurement Notes

Verify the specific suffix 'DSET' versus 'DSER' against the manufacturer's official datasheet to confirm packaging type and tape-and-reel specifications. Ensure the component matches the required 6-WSON package dimensions and thermal characteristics for your design. Cross-reference the exact part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a system requires both a boosted voltage and a stable LDO output from a single low-voltage source. It is suitable for designs prioritizing minimal board space due to its small WSON package. Consider the 350mA boost current limit and 200mA LDO current limit to ensure they meet load requirements. Evaluate the 0.7V minimum input voltage capability against your battery discharge curve.

Part Context

This part belongs to the TPS61098x series of dual-output PMICs designed for low-power applications. It shares architectural similarities with other members like the TPS61098DSET but differs in specific output configurations and current ratings. The series targets markets demanding high integration and energy efficiency in compact form factors.

Replacement Considerations

The TPS610985DSET is a documented alternative within the same family offering similar functionality. Verify pin compatibility and electrical parameters before substitution. Other series members may require schematic adjustments due to differing output currents or voltage settings.
