Aditya Kulkarni, senior product marketing engineer at Power Integrations said: “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 dramatically 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. InnoSwitch3-PD ICs 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.”

Featuring no-load power consumption as low as 14 mW, power supply designs using InnoSwitch3-PD ICs meet all global energy-efficiency regulations. The high efficiency of these devices ensures low heat dissipation, eliminating the need for bulky heatsinks. Power Integrations’ FluxLink high-speed communications feedback link ensures fast, accurate secondary-side regulation. InnoSwitch3-PD ICs are also fully protected, with input voltage monitoring, accurate brown-in/brown-out and overvoltage protection, and output over- and under-voltage fault detection with independently configurable fault responses.
