Sunnyvale, Calif.In an effort to help designers shrink DC/DC converter designs, Alpha & Omega Semiconductor Inc. (AOS) is offering its AON740x advanced MOSFET family in the compact DFN3x3EP package.
According to Alpha & Omega Semiconductor, it is the first to offer a monolithically integrated Schottky diode (SRFET) in this type of package.
The product family is aimed at space-constrained applications that require high efficiency DC-DC conversion such as notebook PCs, blade servers, networking equipment, graphics cards and DC-DC power supply modules.
The DFN3x3EP package allows DC/DC designers to achieve higher 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 3mm x 3mm package saves space by using only one-third the board area of an SO-8. At the same time, this smaller-sized DFN3x3EP package maintains same the same 60 degrees C/W thermal performance as SO-8-packaged devices.
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 for optimal efficiency and performance. 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.
Pricing: In 1,000-piece quantities ranges from 31 cents to 60 cents each.
Availability: These devices are available immediately in production quantities.
Datasheets: AON7400, AON7700, AON7406, AON7702, AON7408, AON7704.
