Power Integrations Launches InnoSwitch™3-AQ Flyback Switcher for Advanced Automotive Applications

Power Integrations Unveils Advanced InnoSwitch™3-AQ Flyback Switcher for Automotive Applications

Power Integrations, a frontrunner in high-voltage integrated circuits, presents a new wide-creepage package option for its InnoSwitch™3-AQ flyback switcher IC, tailored specifically for the automotive sector. This innovative package achieves a significant drain-to-source creepage distance of 5.1 mm, aligning with the IEC60664-1 standard required for 800 V vehicles. Notably, this design eliminates the need for conformal coating, thereby streamlining the manufacturing process and bolstering system reliability. As electric vehicles (EVs) continue to evolve, the introduction of this advanced IC represents a critical step forward in accommodating the increasing voltage demands of next-generation automotive applications.

Mike Stroka, product marketing engineer at Power Integrations, emphasizes the advantages that automotive designers gain from the InnoSwitch™3-AQ ICs. These devices not only support higher voltage bus systems but also promote efficiency and reduce the overall component count in vehicle designs. The InSOP™-28G package facilitates a robust performance, allowing for 1000 VDC operation on the primary side while ensuring proper isolation for other pins, even in pollution degree 2 environments. This capability is vital for enhancing the durability and functionality of automotive electronics, which must withstand rigorous operating conditions.

The InnoSwitch™3-AQ ICs harness the potential of silicon carbide (SiC) technology, integrating a primary switch rated for 1700 V that can deliver up to 80 watts of output power. This innovation leads to a reduction in component requirements by as much as 50%, promoting space efficiency and system reliability. Additionally, the ICs are designed with critical safety features, including input under-voltage and output over-voltage protection, ensuring safe operation in various scenarios. With an efficiency of over 90% and a power consumption of less than 15 mW at no-load, these ICs are ideal for applications such as battery management systems and emergency power supplies. The new devices are competitively priced at $6 per unit for orders of 10,000, with samples currently available and full-scale production anticipated by early 2025.

Power Integrations continues to lead the charge in the automotive power electronics sector, responding to the growing demand for higher efficiency and reliability in EV systems. The launch of the InnoSwitch™3-AQ not only reflects the company’s commitment to innovation but also positions it strategically to address the evolving needs of the automotive market. Interested customers can reach out to Power Integrations or its authorized distributors for further information on these advanced ICs.
