PD - 95024 IRF7822PbF
HEXFET® Power MOSFET for DC-DC Converters
• N-Channel Application-Specific MOSFETs • Ideal for CPU Core DC-DC Converters • Low Conduction Losses A 1 • Low Switching Losses 8 S D • Lead-Free 2 7 S D 3 6 S D
Description
4 5 G D This new device employs advanced HEXFET Power MOSFET technology to achieve an unprecedented balance of on-resistance and gate charge. The reduced SO-8 T op V iew conduction and switching losses make it ideal for high efficiency DC-DC converters that power the latest generation of microprocessors. DEVICE CHARACTERISTICS 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. R 5.0mΩ DS(on) DS(on) The IRF7822 offers particulary low R and high Cdv/ DS(on) Q 44nC G dt immunity for synchronous FET applications. Q 12nC sw The package is designed for vapor phase, infra-red, Q 27nC oss convection, or wave soldering techniques. Power dissipation of greater than 3W is possible in a typical PCB mount application.
