HEXFET® Power MOSFET for DC-DC Converters
• N-Channel Application-Specific MOSFETs • Ideal for CPU Core DC-DC Converters • Low Conduction Losses A 1 8 • Low Switching Losses S D 2 7 S D
Description
3 6 S D This new device employs advanced HEXFET Power 4 5 MOSFET technology to achieve an unprecedented G D balance of on-resistance and gate charge. The reduced conduction and switching losses make it ideal for high SO-8 T o p V ie w efficiency DC-DC converters that power the latest generation of microprocessors. DEVICE CHARACTERISTICSU The IRF7822 has been optimized for all parameters that are critical in synchronous buck converters including

R , gate charge and Cdv/dt-induced turn-on immunity. DS(on) The IRF7822 offers particulary low R and high Cdv/ R 5.0m DS(on) Ω DS(on) dt immunity for synchronous FET applications. Q 44nC G The package is designed for vapor phase, infra-red, Q 12nC sw convection, or wave soldering techniques. Power Q 27nC dissipation of greater than 3W is possible in a typical oss PCB mount application.
