SYNCHRONOUS BUCK CONVERTER
Dual FETKY, IRF7901D1, integrates all power components for a synchronous buck converter into a single SO-8 package
|Achieve 94% Peak Efficiency with IR’s Dual FETKY®|
|Patented FETKY® devices are co-packaged HEXFET® Power MOSFETs and Schottky diodes. Co-packaging reduces packaging and assembly costs and increases power density in power subsystems. A FETKY device offers a substantial 60% space savings over the discrete solution which is essential to achieve high power densities in a small form factor required by portable applications.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.
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.
