Industry’s First Automotive-Qualified HV Switcher ICs with 1700 V SiC MOSFET

Power Integrations announced the addition of two new AEC-Q100 qualified, 1700-volt rated ICs to its InnoSwitch™3-AQ family. The new devices are the industry’s first automotive-qualified switching power supply ICs to incorporate a silicon carbide (SiC) primary switching MOSFET. Delivering up to 70 watts of output power, the new ICs are targeted for use in 600- and 800-volt battery and fuel-cell electric passenger vehicles, as well as electric buses, trucks and a wide range of industrial power applications.

Highly integrated InnoSwitch ICs reduce the number of components required to implement a power supply by as much as 50 percent, saving significant circuit-board space, enhancing system reliability and mitigating component sourcing challenges. Devices from the award-winning InnoSwitch family are now available with a choice of cost-effective silicon, high-efficiency gallium nitride (GaN) and high-voltage SiC transistors, permitting designers to optimize their power solution across a broad range of consumer, computer, communications, industrial and automotive applications.

Offered in a compact InSOP™-24D package, the new ICs use a FluxLink™ feedback link, providing reinforced isolation up to 5000 Vrms for secondary-side control (more info, graphic: Business Wire).
