Description
T op V ie w
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
TM
the smallest footprint available in an SOIC outline. This makes the Micro8 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.
