IRF7811W

HEXFET^®Power MOSFET for DC-DC Converters

• N-Channel Application-Specific MOSFETs

• Ideal for CPU Core DC-DC Converters

• Low Conduction Losses

• Low Switching Losses

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.

DEVICE CHARACTERISTICSꢀ

The IRF7811W has been optimized for all parameters

that are critical in synchronous buck converters including

R_DS(on), gate charge and Cdv/dt-induced turn-on immunity.

The IRF7811W offers particulary low R_DS(on)and high Cdv/

dt immunity for synchronous FET applications.
