Power Integrations Launches New InnoSwitch3-AQ IC Package for Automotive Power Efficiency

Power Integrations Unveils Innovative IC Package for Automotive Applications

Power Integrations, a recognized leader in high-voltage integrated circuits geared toward energy-efficient power conversion, announces the launch of a new wide-creepage package option for its InnoSwitch™3-AQ flyback switcher integrated circuit (IC). This development is particularly focused on automotive applications, addressing the growing demand for reliable and efficient power solutions in electric vehicles (EVs). The new package boasts a drain-to-source creepage distance of 5.1 mm, meeting the stringent IEC60664-1 standard for 800 V vehicles without the need for conformal coating. This advancement not only simplifies the manufacturing process but also enhances overall system reliability, a crucial factor in automotive design.

According to Mike Stroka, a product marketing engineer at Power Integrations, the InnoSwitch3-AQ ICs present automotive designers with significant advantages, including improved efficiency and a reduced component count. These features are particularly beneficial for the next generation of EV bus voltages, as the device’s InSOP™-28G package supports 1000 VDC on the primary side while ensuring isolation for other pins in pollution degree 2 environments. This capability is vital for maintaining safety and performance standards in automotive applications, where reliability is paramount. Moreover, the ICs leverage cutting-edge silicon carbide (SiC) technology, allowing them to deliver up to 80 watts of output power and cut component requirements by as much as 50%. This reduction plays a crucial role in optimizing space and enhancing the reliability of electric vehicle systems.

The InnoSwitch3-AQ ICs are designed to operate efficiently, starting with as little as 30 volts on the drain and featuring essential safety mechanisms such as input under-voltage and output over-voltage protection. With over 90% efficiency and a no-load consumption of less than 15 mW, these ICs are well-suited for various applications, including battery management systems and emergency power supplies. Power Integrations offers these innovative ICs at a price point starting at $6 per unit for larger orders, with samples currently available and full production anticipated by early 2025. This strategic move positions Power Integrations at the forefront of the automotive power solutions market, catering to the evolving needs of electric vehicle manufacturers.

In addition to the introduction of the new IC package, Power Integrations continues to strengthen its commitment to innovation and sustainability within the automotive sector. The company actively collaborates with automotive designers and manufacturers to ensure its products meet the highest standards of efficiency and reliability. As the demand for electric vehicles surges, Power Integrations is poised to play a critical role in shaping the future of automotive power solutions.
