MOSFET and Schottky Diode
General Description
This device is designed specifically as a single package solution
for a boost topology in cellular handset and other ultra-portable
applications. It features a MOSFET with low on-state resistance,
and an independently connected schottky diode with low forward
voltage.
The MicroFET 2x2 package offers exceptional thermal
performance for its physical size and is well suited to switching
and linear mode applications.
