AO4812/MC4812  
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.
