Overview
The TPS610986DSER is a synchronous boost DC-DC converter manufactured by Texas Instruments, designed for low input voltage applications. It features a dual-output configuration providing a fixed 3.3V output with a maximum current of 500 mA. The device operates within an input voltage range of 0.7V to 4.5V and maintains a typical quiescent current of 300 nA. It supports an adjustable switching frequency and functions reliably across an operating temperature range from -40°C to +85°C. The component is housed in a compact 6-WSON package.
Feature Summary
- Dual-output topology combining a synchronous boost converter with a linear regulator
- Ultra-low quiescent current consumption for extended battery life
- Adjustable switching frequency for optimized efficiency and noise management
Applications
- Low input voltage step-up power supplies
- Portable electronic devices requiring efficient power conversion
- Battery-powered systems with strict standby current requirements
Procurement Notes
Verify the specific suffix 'DSE' against the official datasheet to confirm pinout and thermal characteristics. Ensure the WSON-6 package dimensions match your PCB footprint constraints. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a single IC solution is needed for both boosted and regulated outputs from a low-voltage source. Consider the 300 nA quiescent current as a key differentiator for energy-sensitive designs. Evaluate the adjustable frequency feature against EMI requirements. Compare the 6-WSON package size against available board space relative to other PMIC options.
Part Context
This part belongs to the TPS61098 series of power management integrated circuits. The series focuses on integrating multiple regulation stages into a small form factor. It targets applications where space is limited and high efficiency at light loads is critical. The dual-output design simplifies bill of materials by replacing separate boost and LDO components.
Replacement Considerations
Check for direct substitutes within the TPS61098 family, such as TPS61098DSET or TPS610985DSET, verifying output voltage and current ratings. Ensure any replacement matches the 6-WSON package and electrical specifications.
