Transphorm aims TOLL GaN FETs at power hungry AI
Transphorm has developed a leadless package for three of its normally-off D-Mode SuperGaN devices for power hungry AI applications.
The SuperGaN FETs in TO-leadless (TOLL) packages have on-resistances of 35, 50, and 72 milliohms and are in an industry standard package configuration as a drop-in replacements for any e-mode TOLL device.
The robust 650 V SuperGaN TOLL devices are JEDEC qualified. Because the normally-off d-mode platform pairs the GaN HEMT with a low voltage silicon MOSFET, the SuperGaN FETs are easy to drive with commonly used off-the-shelf gate drivers. They can be used in various hard- and soft-switching AC-to-DC, DC-to-DC, and DC-to-AC topologies to increase power density while reducing system size, weight, and overall cost.
- GaN hits Short Circuit robustness requirement for motor control
- Transphorm takes on SiC with simulation model
- Microchip teams for 3 kW GaN inverter .
The devices also offer Transphorm’s high voltage dynamic switching on-resistance reliability for higher power applications operating within an average range of 1 to 3 kilowatts. These power systems are typically found in high performance segments such as computing (AI, server, telecom, data centre), energy and industrial (PV inverters, servo motors) and other industrial markets.
Transphorm’s high power GaN devices are already used in datacentre power supplies, high power gaming PSUs, UPSes, and microinverters. These applications can also be supported by the TOLL devices as can electric-vehicle-based DC-to-DC converters and onboard chargers, with the underlying SuperGaN die already automotive (AEC-Q101) qualified.
The SuperGaN TOLL FETs represent the sixth package type offered by Transphorm and harness the inherent performance and reliability advantages made possible by the normally-off d-mode SuperGaN platform.
The SuperGaN TOLL devices are currently available to sample.
