Eggtronic has announced an AC/DC demo and development board to speed the design, prototyping and implementation of high-efficiency, high-performance, ultra-compact power converters, power adapters and device chargers. The new 35W AC/DC development board uses its EcoVoltas QuarEgg+ technology. Ideal for USB-PD and fixed power output applications, the board is available with a GaN FET (for maximum performance) or a silicon FET (for cost-effective, high-performance solutions).
It developed the EcoVoltas proprietary, patented power conversion architecture to help engineers fulfil long-term goals on cost, size, weight and sustainability. The architecture boosts the performance of FET switching devices, whether they are based on legacy silicon or GaN and SiC WBG materials. EcoVoltas QuarEgg+ micro-sized, ultra-efficient power converters provide up to five times lower losses and are twice as small as traditional silicon converters and have up to two times lower losses and are 30% smaller than previous GaN converters.
The new AC/DC development board combines the FETs with all components required to produce a working USB-PD or fixed-output converter. Peak efficiency is more than 94%, while a very flat efficiency curve ensures maximum efficiency and minimum power losses across the widest possible spectrum of loads. Using the development board, designers can also reduce so-called ‘vampire power’ thanks to no-load power consumption below 18mW.
Measuring only 38.3mm x 38.3mm x 18.6mm, the new board can accommodate a wide input voltage range of 90VAC to 264VAC. Configurable output options are 5V/3A, 9V/3A, 12V/2.9A, 15V/2.3A and 20V/1.75A. A version of the development board with easy access to every testing point is also provided for the simplified design of QuarEgg based power adapters.
“By taking a fundamentally different approach to manipulating and converting power, EcoVoltas QuarEgg+ supports the creation of the smallest, most efficient and environmentally friendly power converters,” says Igor Spinella, Eggtronic’s CEO and founder. “The 35W AC/DC development board allows engineers to very quickly realise the size, weight, cost, efficiency and design flexibility that QuarEgg+ offers in their latest USB-PD and fixed output power adapter designs.”
