DESCRIPTION
This new generation of Trench MOSFETs from Zetex utilizes a unique
structure that combines the benefits of low on-resistance with fast switching
speed. This makes them ideal for high efficiency, low voltage, power
management applications.
FEATURES
Low on-resistance
Fast switching speed
Low threshold
Low gate drive
Low profile SOIC package
APPLICATIONS
DC - DC converters
Power management functions
Disconnect switches
Motor control
