Description 4 5
This new device employs advanced HEXFET Power G LIE 313 C)
MOSFET technology to achieve an unprecedented
balance of on-resistance and gate charge. The reduced SO-8 Top View
conduction and switching losses make it ideal for high
efficiency DC-DC converters that power the latest
generation of microprocessors. DEVICE CHARACTERlSTlCSS
The IRF7811W has been optimized for all parameters IRF7811W
that are critical in synchronous buck converters including
RDSM, gate charge and Cdv/dt-induced turn-on immunity. Roam, 9.0mQ
The IRF7811W offers particulary low Roman) and high Cdv/ Q 22nC
dt immunity for synchronous FET applications. G
st 10.1 nC
The package is designed for vapor phase, infra-red, Q 12nC
convection, or wave soldering techniques. Power oss
dissipation of greater than 3W is possible in a typical
PCB mount application.
