0.080-Ohm 12A / 650V GaN Switches

VisIC Technologies, Ltd. is announcing the launch of a new product, offered in a smaller package with bottom side cooling, an on resistance RDS(on) rating of 0.080Ω, and a reduced external components requirement using a simplified driving scheme.

This new 650V GaN Power Switch is a member of the ALL-Switch family designed for bridge converters in motor drives, power supplies, chargers, UPS, Inverters and other circuits requiring high efficiency and currents up to 12A.

VisIC Technology's designs operate with lower gate charge and capacitance than competitive products while providing the benefits of low RDS(on). Offered in low inductance packaging, the ALL-Switch family is able to deliver high efficiency. For comparison, ALL-Switch's switching losses are 3-5 times lower than comparable SIC MOSFET transistors operating at the same frequency.

ALL-Switch is a System In Package (SIP) switch. A Normally-Off safe function is integrated within the package, designed according to SmartGaN topology, an innovation by VisIC Technologies. ALL-Switch V22N65A combines a patented, high-density, lateral-layout GaN power transistor and control block circuitry into a product with extremely low RDS(ON), exceptionally fast switching performance and a conveniently small footprint. It is very effective in applications requiring high efficiency, high power density and low cost.

The V80N65B answers the need expressed by many of VisIC's customers for a bottom-side cooled package in their designs after they have experienced ALL-Switch's low switching losses. The V80N65B Bottom-side cooled power switch supplements VisIC's, existing ALL Switch top-side cooled product line of 650V GaN devices: The V22N65A, V22S65A, and V18G65A.
