Analog Power
AM7640N
Dual N-Channel 40-V (D-S) MOSFET
These miniature surface mount MOSFETs utilize a
high cell density trench process to provide low
rDS(on) and to ensure minimal power loss and heat
dissipation. Typical applications are DC-DC
converters and power management in portable and
battery-powered products such as computers,
printers, PCMCIA cards, cellular and cordless
telephones.

•
Low rDS(on) provides higher efficiency and S2
extends battery life
G2
• Low thermal impedance copper leadframe
DFN3x3-8PP saves board space
• Fast switching speed
• High performance trench technology
