SPN3446
N-Channel Enhancement Mode MOSFET
DESCRIPTION
The SPN3446 is the N-Channel logic enhancement mode
power field effect transistors are produced using high cell
density , DMOS trench technology.
This high density process is especially tailored to
minimize on-state resistance.
These devices are particularly suited for low voltage
application such as cellular phone and notebook
computer power management and other battery powered
circuits, and low in-line power loss are needed in a very
small outline surface mount package.
APPLICATIONS
Power Management in Note book
Portable Equipment
Battery Powered System
DC/DC Converter
Load Switch
DSC
LCD Display inverter
