TPS610982DSER

Overview

The TPS610982DSER 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 of 3.3 V. The device supports a maximum output current of 350 mA with a typical quiescent current of 300 nA. It features an adjustable switching frequency and includes shutdown functionality. The component is housed in a WSON-6 package and is rated for operation between -40°C and +85°C.

Feature Summary

• Synchronous boost topology for high efficiency
• Ultra-low quiescent current for battery preservation
• Adjustable switching frequency for optimization
• Integrated shutdown mode for power management

Applications

• Portable electronic devices requiring efficient power conversion
• Battery-powered systems with low input voltage sources
• Applications necessitating extended battery life through low standby current
• Space-constrained designs utilizing compact surface-mount packaging

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when sourcing. Confirm that the TPS610982 variant matches the required 3.3 V fixed output specification for your design. Ensure compatibility with the WSON-6 footprint during PCB layout. Cross-reference the manufacturer datasheet for thermal performance requirements under load conditions.

Selection Notes

Select this component when a fixed 3.3 V output is required from a single-cell lithium-ion or similar low-voltage source. Consider the 350 mA current limit against peak load demands. Evaluate the adjustable frequency feature against electromagnetic interference constraints. Compare the 300 nA quiescent current against other regulators if ultra-low standby power is critical.

Part Context

This part belongs to the TPS61098 family of synchronous boost converters from Texas Instruments. These devices are engineered for portable applications where space and power efficiency are paramount. The family offers various output configurations and current ratings to suit different system requirements while maintaining a consistent small form factor.

Replacement Considerations

TPS610982DSET serves as a tape-and-reel alternative to the standard cut-tape version. Verify pinout compatibility before substitution. Check if the TPS610985 variant meets requirements, noting its dual-output capability differs from the single-output TPS610982.
