N-Channel Application-Specific MOSFETs
• Ideal for CPU Core DC-DC Converters
• New
CopperStrapTM Interconnect for Lower
Electrical and Thermal Resistance
• Low Conduction Losses
• Low Switching Losses
• Minimizes Parallel MOSFETs for high
current applications
Description
These new devices employ advanced HEXFET® Power
MOSFET technology to achieve an unprecedented
balance of on-resistance and gate charge. The reduced
conduction and switching losses make them ideal for
high efficiency DC-DC converters that power the latest
generation of mobile microprocessors.
The IRF7809/IRF7811 employs a new
CopperStrapTM
interconnect technology pioneered by International
Rectifier to dramatically improve the electrial & thermal
resistance contribution of the package. The new
CopperStrap SO-8 power MOSFETs are capable of
current ratings over 17A and power dissipation of 3.5W
@ 25
°C ambient conditions, thereby reducing the need
for paralleled devices, improving efficiency and
reliability and reducing board space.
