POWER INTEGRATIONS InnoSwitch 3-PD compact InSOP-24D-packaged IC includes a USB-C and PD controller, a high-voltage PowiGaN switch, a multi-mode quasi-resonant flyback controller, secondary-side sensing, FluxLink isolated digital feedback and a synchronous-rectification driver. Devices target designers seeking the ultimate in charger power density, requiring a high level of integration and maximum efficiency to limit self-heating. Device simplifies the development and manufacturing of compact, energy-efficient USB PD power supplies for smartphones, tablets, notebooks, and other devices that benefit from fast charging. Devices reduce the BOM count to half that of conventional designs, reducing design time and simplifying high-volume manufacture for slim, ultra-compact OEM and aftermarket chargers.
