TPS61103PWR

Overview

The TPS61103PWR is a switching voltage regulator manufactured by Texas Instruments, featuring a high-efficiency boost converter with an integrated 120mA LDO. It operates within an input voltage range of 0.8 V to 3.3 V and utilizes current-mode control with pulse width modulation. The device is housed in a 24-pin HVQCCN package (LCC24) measuring 4 mm in length. It complies with RoHS standards and carries an EAR99 classification.

Feature Summary

• Integrates a high-efficiency boost converter with a dedicated 120mA low-dropout linear regulator
• Employs current-mode control architecture for stable regulation
• Operates on a wide input voltage range starting from 0.8 V

Applications

• Portable battery-powered devices requiring efficient voltage step-up
• Systems utilizing single-cell lithium-ion or lithium-polymer batteries
• Embedded applications needing combined regulated and unregulated power rails

Procurement Notes

Verify the specific package suffix 'PWR' against official datasheets to confirm pinout and thermal characteristics. Ensure compatibility with the required 24-pin HVQCCN footprint during PCB layout. Confirm RoHS compliance status for your region's regulatory requirements before finalizing procurement.

Selection Notes

Select this component when a compact solution is needed for boosting low input voltages up to higher levels while providing a separate clean analog supply via the internal LDO. Consider the 24-pin QFN package constraints for thermal management and trace routing. Evaluate if the 120mA LDO current limit meets the load requirements for auxiliary circuits.

Part Context

This part belongs to the TPS6110x series of DC-DC converters designed for space-constrained portable electronics. It combines switching regulation with linear regulation to simplify power tree design. The Texas Instruments portfolio focuses on high integration and efficiency for mobile and wearable applications.

Replacement Considerations

Consult official substitution guides for direct replacements. Verify pin-to-pin compatibility and electrical parameter equivalence before swapping components in existing designs.
