Incorporating a robust PowiGaN gallium-nitride primary switch and steady-state switching frequency of up to 140 kHz, the highly integrated devices reduce the component count and PCB area required for ultra-compact adapters for cellphone, notebook, tablet and multi-port accessories.\nThis press release features multimedia.

Efficiency exceeds 95 percent, which enables designers to eliminate the heat sinks, spreaders and potting materials typically required for thermal management.\"\n\nFurther size reduction of the adapter can be achieved by the use of a MinE-CAP™ device in combination with InnoSwitch4-Pro and ClampZero ICs. Based also on PowiGaN technology, MinE-CAP ICs enable input capacitance size reduction of approximately 40 percent.\n\nCapable of delivering up to 220 W, InnoSwitch4-Pro ICs combine a 750 V PowiGaN primary switch, controller, FluxLink™ reinforced isolation feedback link for secondary-side control, I2C interface, active clamp drive and synchronous rectification in a compact InSOP™-28 package. The high level of integration greatly simplifies the development and manufacturing of fully programmable, highly efficient power supplies. These programmable flyback ICs in combination ...
