TPS61103PW

Overview

The TPS61103PW is a switching voltage regulator manufactured by Texas Instruments, housed in a 20-pin TSSOP package. It functions as a high-efficiency boost converter with an integrated 3.3V LDO output. The device operates within an input voltage range of 0.8 V to 3.3 V, with a nominal input of 1.8 V. Utilizing current-mode control and pulse width modulation, it regulates DC-DC conversion. The component complies with RoHS standards and carries an EAR99 classification.

Feature Summary

• Integrates a high-efficiency boost converter topology with a dedicated 3.3V low-dropout regulator output.

Applications

Procurement Notes

Verify the specific suffix 'G4' against official documentation to confirm environmental compliance status and exact pin configuration. Ensure the TSSOP-20 package dimensions match the design requirements. Cross-reference the manufacturer's latest datasheet for any updates on lead times or availability constraints before finalizing procurement plans.

Selection Notes

Select this component when a combined boost and LDO solution is required from a single IC. The wide input voltage range supports various battery types. Consider the thermal performance of the TSSOP package for the intended power dissipation levels. Verify that the 120mA LDO current capability meets the load requirements.
