Aditya Kulkarni, senior product marketing engineer at Power Integrations, states, “The InnoSwitch3-PD ICs target designers seeking the ultimate in charger power density. This requires the highest level of integration and maximum efficiency to limit self-heating. Our latest addition to the InnoSwitch3 family greatly simplifies the development and manufacturing of compact, energy-efficient USB PD power supplies for smartphones, tablets, laptops, and other devices that benefit from fast charging.” The InnoSwitch3-PD integrated circuits reduce the bill of materials by half compared to conventional designs, thereby reducing design time and simplifying the high-volume manufacturing of ultra-compact chargers for OEMs and the aftermarket.”.
With a no-load power consumption of only 14 mW, power supply designs using InnoSwitch3-PD ICs meet all global energy efficiency standards. The high efficiency of these devices ensures low heat dissipation, eliminating the need for bulky heatsinks. Power Integrations' high-speed FluxLink communication feedback link guarantees fast and precise secondary-side regulation. InnoSwitch3-PD ICs are also fully protected, with input voltage monitoring, overvoltage and input/output protection, and output overvoltage and undervoltage fault detection with independently configurable fault responses.
