N-Channel 40-V (D-S) MOSFET
These miniature surface mount MOSFETs utilize
High Cell Density process. Low rDS(on) assures
minimal power loss and conserves energy, making
this device ideal for use in power management
circuitry. Typical applications are PWMDC-DC
converters, power management in portable and
battery-powered products such as computers,
printers, battery charger, telecommunication power
system, and telephones power system.
• Low rDS(on) Provides Higher Efficiency and
Extends Battery Life
• Miniature SO-8 Surface Mount Package
Saves Board Space
• High power and current handling capability
• Low side high current DC-DC Converter
