N-Channel Application-Specific MOSFETs
Ideal for CPU Core DC-DC Converters
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
microprocessors.
Both the IRF7809A and IRF7811A have been optimized
and are 100% tested for all parameters that are critical in
synchronous buck converters including R
, gate charge
and Cdv/dt-induced turn-on immunity. The IRF7809A offers
particulary low R
and high Cdv/dt immunity for
synchronous FET applications. The IRF7811A offers an
extremely low combination of Q
sw
& R
DS(on)
for reduced
losses in control FET applications.
The package is designed for vapor phase, infra-red,
convection, or wave soldering techniques. Power
dissipation of greater than 2W is possible in a typical PCB
mount application.
