SkyWater Technology and Applied Novel Devices, Inc. announced a major industry breakthrough with new transistor technology that offers significant benefits for fast switching power conversion applications. The power MOSFETs offer 2x lower output charge, near-zero reverse-recovery, and ultra-low Qoss enabled by AND’s proprietary channel engineering technology. In addition, these power MOSFETs offer superior specific on-resistance (< 5 mOhm-mm2 @ 30V BVDSS) at gate drive as low as 2.5V as well as low leakage currents and near-ideal sub-threshold slope made possible by AND’s device architecture. These characteristics can substantially reduce parasitic losses incurred in power management systems. This will improve power management and conversion efficiency in numerous applications including data centers, automotive, electric motor drives, microinverters for renewable energy systems, and many others in industrial and consumer markets.
In applications such as DC-DC power conversion, AND’s technology offers unique advantages enabled by its novel device architecture. Near-zero reverse recovery and low output capacitances eliminate the need for integrated or standalone Schottky clamp diodes. These efficiency-enhancing characteristics make the technology attractive for higher frequency voltage conversion applications not typically supported by conventional Si MOSFETs. The high frequencies enabled by these power MOSFETs, in turn, drive the reduction of passive component sizes to achieve small form factor power modules that support further system-level efficiency gains.
AND will offer wafer-scale and standard package products ranging from 15-80V for industrial and consumer applications. AND plans to expand the offering to span the 200-1000V range with a family of products produced at SkyWater for electric vehicles, renewable energy, and various industrial applications. Additionally, through a technology licensing agreement, SkyWater will offer this power MOSFET technology process flow to foundry customers.
AND is currently sampling the new power MOSFETs and in the process of ramping production at SkyWater. The devices in wafer-scale packages will be tailored to specific form factors for existing boards and systems. The products are available from AND and the technology is available immediately as a foundry offering directly from SkyWater.
