SYNCHRONOUS BUCK CONVERTER
IR’s Dual FETKY, IRF7901D1, integrates all power components for a synchronous buck converter into a single SO-8 package
A common application for FETKY devices is in a synchronous buck converter in which the Schottky diode carries current during conduction dead time. A FETKY device minimizes stray package and PCB trace inductance between the synchronous FET and the Schottky that parallels it, simplifying board layout and increasing efficiency.
IR’s IRF7901D1 dual FETKY integrates all power components for a synchronous buck converter in a single SO-8 package. It offers 200% increased power density than a discrete solution and offers 94% efficiency in a 5A, sub 1V buck converter.
