Dual N-Channel 30-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.
