Posted on 245 Keysight Technologies, Inc. (NYSE: KEYS), a leading technology company that helps enterprises, service providers and governments accelerate innovation to connect and secure the world, and Transphorm, Inc. (OTCQB: TGAN), a global supplier of high reliability, high performance gallium nitride (GaN) power conversion products, have announced the availability of a new power supply reference design that enables engineers to identify and correct design errors before building hardware, thereby lowering product costs and speeding time to market. Switched-mode power supplies provide greater efficiency, increased power density and lower overall system costs when using GaN devices. However, GaN, a high switching speed, high performance wide bandgap semiconductor, can produce voltage spikes that result in detrimental radiated electromagnetic interference. As a result, optimized layout design and placement of components before building hardware is critical when using GaN.
