Suiting high-current dc/dc converters in notebooks, high-end desktops and servers, and advanced telecom and datacom systems, the DirectFET MOSFET chip set includes the IRF6712S control FET and IRF6716M synchronous FET.  The IRF6716M provides a 1.2-mΩ typical on-resistance at 10V gate-to-source voltage and 2-mΩ on-resistance at 2V gate-to-source voltage. The IRF6712S achieves a 12-nC gate charge and a 4.4-nC gate-to-drain charge, as well as a 3.8-mΩ typical on-resistance at 10V gate-to-source voltage and a 6.7-mΩ on-resistance at 4.5V gate-to-source voltage. Available in an MX-pad outline with a 0.7-mm profile, the IRF6712S and IRF6716M cost 59 cents (10,000) and $1.27 (10,000), respectively.
