A Synchronous DC-DC Buck Regulator is a power management solution designed to efficiently step down a higher input voltage to a lower, stable output voltage. Unlike traditional buck regulators, the synchronous variant replaces the freewheeling diode with a low-resistance MOSFET, significantly improving conversion efficiency by reducing power losses during operation. https://tenxerlabs.com/livebench/labs/synchronous-dc-dc-buck-regulator/
