Eggtronic has launched a new AC/DC demo and development board to speed the design and prototyping of high-efficiency, ultra-compact power converters, power adapters, and device chargers. Built on Eggtronic’s EcoVoltas QuarEgg+ conversion architecture technology, the 35-W AC/DC development board is available with a gallium nitride (GaN) FET or a silicon FET, depending on performance and cost requirements.
The EcoVoltas architecture improves the performance of FET switching devices, whether they are based on legacy silicon or GaN and silicon carbide (SiC) wide bandgap (WBG) materials, said Eggtronic. The EcoVoltas QuarEgg+ micro-sized, ultra-efficient power converters are said to offer up to five times lower losses than traditional silicon converters and up to two times lower losses than previous GaN converters. In addition, it is twice as small as silicon converters and 30% smaller than previous GaN converters.

The AC/DC development board combines the FETs with all of the components needed to deliver a working USB-PD or fixed-output converter, said Eggtronic. Peak efficiency is said to be greater than 94% with a very flat efficiency curve, which ensures maximum efficiency and minimum power losses across the widest possible range of loads. The board also helps minimize “vampire power,” thanks to a no-load power consumption that is below 18 mW, said the company.
Available now, the development board measures 38.3 × 38.3 × 18.6 mm and can accommodate a wide input voltage range of 90 VAC to 264 VAC. Configurable output options are 5 V/3 A, 9 V/3 A, 12 V/2.9 A, 15 V/2.3 A and 20 V/1.75 A. A version is available with easy access to all testing points for simplified design of QuarEgg-based power adapters.
Eggtronic’s E2WATT Hybrid AC Power Solution is an Electronic Products Product of the Year Award winner for the power category.
