From the project

I have completed the schematic and PCB layout for a high-current buck converter using the Texas Instruments TPS56A37RPAR, designed to deliver 6.0V at 6.0A from an input range of 11.0V to 22.0V.

🚀 Complete 6A Synchronous Buck Converter — Now Available on GitHub!

I’m pleased to share my fully completed power delivery design: a high-efficiency, robust buck converter based on the Texas Instruments TPS56A37RPAR, engineered to deliver 6.0 V at 6.0 A from an input voltage range of 11.0 V to 22.0 V.

This project represents a complete end-to-end hardware development cycle—from initial simulation in TI WEBENCH® to final PCB layout in Altium Designer—and is designed for reliable performance and straightforward manufacturability.
