FiDUS Power establishes a unique size in the external power supply market, with the launch of the new model GDA200. The use of Gallium Nitride (GaN) rather than silicon switches matches a confident industry move towards the former, as it’s believed to provide increased efficiency, reduced heat losses and operate at higher frequencies, allowing the size of magnetics and other components to be reduced. The result is a 200W external desktop power supply with a power density rating at 12.5W/In³.

The FiDUS GDA200 will be advantageous to designers of portable equipment and instrumentation in markets including; high end audio, test and measurement, bench top and audio broadcast equipment. The ultra-compact size is also advantageous to customers incorporating external power supplies into their designs to speed up the approvals process. The very small size – 150 x 54 x 33mm (5.9 x 2.12 x 1.3 inches) – may also reduce total system package size resulting in higher shipping and storage densities, especially when the closest competitive product is some 2 ½ times larger. 

Mark Gibbons, engineering manager at FiDUS Power, comments: “The ultra-high power density and small size of our new GDA200 external power supply gives designers of portable products a great deal more value for money and design flexibility. This is the first of a new family of ultra-compact external desk top products to be announced by FiDUS Power with the 300, 160 or 150 and finally GDA 120W series to follow early next year.”
