Power Integrations Launches InnoSwitch3-PD Series Flyback Switch IC with Built in USB PD Controller

     Power Integrations, a well-known company deeply engaged in the field of high voltage integrated circuit energy efficient power conversion, announced the introduction of InnoSwitch 3-PD series IC, which is the industry's most integrated solution for USB Type-C, USB Power Transfer (PD) and USB Digital Control Power Supply (PPS) adapter applications. The new IC is packaged with ultra-thin InSOP-24D, with USB-C and PD controllers, high-voltage PowiGaN switch, multi-mode quasi resonant flyback controller, secondary side detection circuit, FluxLink isolated digital feedback circuit and synchronous rectifier driver integrated inside.

     Aditya Kulkarni, Senior Product Marketing Engineer, Power Integrations, said: "For designers seeking the ultimate power density of chargers, InnoSwitch3-PD IC is the best choice. High power density requires a solution with high integration and efficiency to reduce self heating. As the latest member of our InnoSwitch3 product family, InnoSwitch3-PD IC can greatly simplify the compact, high-energy USB PD power required by smartphones, tablets, laptops and other devices that benefit from rapid charging Source development and manufacturing. InnoSwitch3-PD IC can reduce the number of BOM components to half of the traditional design, thus reducing the design time. For original and non original charger manufacturers, the mass production of ultra-thin and ultra compact chargers can be greatly simplified. "

     The power supply design using InnoSwitch3-PD IC has no load power consumption as low as 14mW, which complies with all global energy efficiency regulations. The high efficiency of these devices can significantly reduce heat dissipation without large heat sinks. The FluxLink high-speed communication feedback link of Power Integrations ensures fast and accurate secondary side adjustment. InnoSwitch3-PD IC also has comprehensive protection functions, including input voltage monitoring, accurate voltage ramp up/down and overvoltage protection, as well as output overvoltage and undervoltage fault detection that can be set separately for fault response.
