Description
Top View
The FETKY^TM family of co-packaged HEXFETs and Schottky diodes offer the
designer an innovative board space saving solution for switching regulator
applications. Generation 5 HEXFETs utilize advanced processing techniques to
achieve extremely low on-resistance per silicon area. Combining this technology
with International Rectifier's low forward drop Schottky rectifiers results in an
extremely efficient device suitable for use in a wide variety of portable electronics
applications like cell phone, PDA, etc.
The new Micro8^TM package, with half the footprint area of the standard SO-8,
provides the smallest footprint available in an SOIC outline. This makes the Micro8^TM
an ideal device for applications where printed circuit board space is at a premium.
The low profile (<1.1mm) of the Micro8^TM will allow it to fit easily into extremely thin
application environments such as portable electronics and PCMCIA cards.
