All hardware in data centers, base stations, and various communications infrastructure utilize power bricks, or custom power supplies. System designers face a number of challenges meeting power supply design requirements including the need to meet the demand for high-power efficiency in the smallest form factor in order to achieve the highest power density at a low cost. One of the key challenges is that Power MOSFETs are becoming a limiting factor to increase power and system density. eGaN FETs have many performance advantages over standard silicon power MOSFETs; including lower switching figure of merit, zero reverse recovery, and an ultra small footprint, and as such greater efficiencies can be achieved with reduced thermal dissipation. This improvement can be used to increase the output power of a size constraint converter, such as a brick, and thus lower cost/watt. Alternatively, it can be used to push the frequency while decreasing size and component count in cost or size sensitive applications – such as buck converters.
