Description

The FETKY™ family of Co-Pack HEXFETMOSFETs and Schottky diodes offers the designer an innovative,

board space saving solution for switching regulator and power management applications. Advanced

HEXFETMOSFETs combined with low forward drop Schottky results in an extremely efficient device suitable

for a wide variety of portable electronics applications.

The SO-14 has been modified through a customized leadframe for enhanced thermal characteristics and

multiple die capability making it ideal in a variety of power applications. With these improvements multiple

devices can be used in an application with dramatically reduced board space. Internal connections enable

easier board layout design with reduced stray inductance.
