GaN power transistors are developed for sub-1kW applications
GaN power semiconductor specialist, GaN Systems has introduced the GS-065 low current (3.5 to 11A) transistor family, developed for sub-1kW power applications. It targets consumer level power supply products such as AC adapters for gaming and workstation laptops, TV power, LED lighting, wireless power systems, and appliance motor drives.
The transistors are based on GaN Systems’ technology in 650V enhancement mode GaN HEMTs. The devices are packaged in thermally efficient, low cost PDFN packages with a small (5.0 x 6.0mm) footprint. The specific device ratings are 3.5, 8.0 and 11A and have an RDS(on) range from 500 to 150mOhm.
GaN Systems offers a range of discrete devices to maximise design freedom, accommodate varied power levels, and allow power system engineers to maintain design control and change parameters to meet specific requirements such as EMI emissions.
The EZDrive circuit evaluation kit has also been introduced. It demonstrates a circuit design that eliminates the need for a discrete driver, resulting in a reduced number of components. It is adaptable to many power levels, switching frequencies, and LLC/PFC controllers.
GaN power transistors enable lightweight electronic devices and faster charging systems. For example, in AC adapters they result in products that are five times smaller and wireless charging solutions that have 50 times more wireless transfer
GaN Systems is displaying these GaN solutions at the Applied Power Electronics Conference (APEC) in Anaheim, California, USA (17 to 21 March 2019, booth 553).
