Alpha & Omega Semiconductor offers its advanced MOSFETs in the DFN3x3EP package and is said to be the first to offer a monolithically integrated Schottky diode (SRFET) in this type of package. This product family is suited for space-constrained applications requiring DC/DC conversion such as notebook PCs, blade servers, networking equipment, graphics cards and DC/DC power supply modules. The new DFN3x3EP package allows DC/DC designers to achieve high current and power density as a result of the package’s exposed copper lead-frame, which permits efficient heat transfer into the printed circuit board. The 3 mm × 3 mm package uses one-third the board area of an SO-8,according to the company, while maintaining 60°C/W thermal performance. The AON740x family consists of fast-switching high-side MOSFETs. They can be combined in synchronous buck converters with the low-side AON770x SRFET family. The SRFET™ device’s Schottky body diode features a low-forward voltage drop of 0.4V that reduces power losses and a soft-recovery characteristic that reduces ringing and associated EMI, according to the company.
