Description
This new device employs advanced HEXFET Power
MOSFET technology to achieve an unprecedented
balance of on-resistance and gate charge. The reduced
conduction and switching losses make it ideal for high
efficiency DC-DC converters that power the latest
generation of microprocessors.

The IRF7822 has been optimized for all parameters that
are critical in synchronous buck converters including
RDS(on), gate charge and Cdv/dt-induced turn-on immunity.
The IRF7822 offers particulary low RDS(on) and high Cdv/
dt immunity for synchronous FET applications.
The package is designed for vapor phase, infra-red,
convection, or wave soldering techniques. Power
dissipation of greater than 3W is possible in a typical
PCB mount application.
