AO4900 / MC4900
Dual N-Channel 30-V (D-S) MOSFET
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.
•
Low r_DS(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
