General Description
These miniature surface mount MOSFETs utilize High
Cell Density process. Low r
DS(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.
