High-speed GaN FET driver switches at 40 MHz
Audio systems are challenged to both minimize size and deliver exceptional audio quality to listeners. At the system-design level, better audio performance and sound quality occur when distortion is reduced. MOSFET components have parasitic diodes and gate capacitance that creates jitter and distortion in class-D audio systems, whereas GaN FETs have much smaller gate capacitance […]
Demo kits for eGaN FETs cover wireless charging standards
Efficient Power Conversion Corporation (EPC) announces the availability of two new demonstration kits – the EPC9127, a complete wireless power kit including a 10 W, class 2 amplifier, category 3 receiver device and the EPC9128, consisting of a 16 W, class 3 amplifier and two receiver devices (categories 3 and 4). These systems, coupled with […]
Laptop power adaptor hits 94% efficiency, squeezes into 3.19 in.3 space
A reference design for a tiny, 65-W, 94% efficient ac/dc power adaptor for laptops measures just 3.19 in.3 and has a power density of 20 W/in3. This high efficiency means that the device runs cooler than standard ac/dc adapters. At the core of this adapter is a synchronous rectifier circuit using 150-V, 7-mΩ EPC2033 eGaN […]
