Power Integrations AC/DC Converter 24V 5 V 24-Pin Surface Mount InSOP-24D TN Series AEC-Q100 INN3947CQ-TL

Power Integrations INN3947CQ-TL is a high-performance AC/DC Converter IC specifically engineered for isolated flyback topologies in automotive and industrial power management applications. Operating with a wide input voltage range from 40 VDC to over 1000 VDC, it delivers a regulated 24 V output and supports a minimum output voltage of 5 V. Its integrated primary and secondary controllers combined with safety-rated feedback enable precise voltage regulation even under wide input voltage variations.

The device features a compact surface mount package (InSOP-24D) with 24 pins, simplifying the PCB layout and assembly process. It exhibits high efficiency reaching up to 90% across the full load range, ensuring minimal power loss and improved energy savings. The converter consumes less than 15 mW at no load, making it energy efficient and eco-friendly.

Robust protection mechanisms are built-in including line over and under voltage protection, output overvoltage and over-current limiting, and over-temperature shutdown, providing reliability and safety in demanding applications. Qualification to the automotive standard AEC-Q100 further underscores its suitability for vehicle power systems.

The switching frequency is 95 kHz, optimized for efficient energy conversion with minimal electromagnetic interference. It meets major international safety and quality standards such as TUV (EN62368), CQC (GB4943.1), EN61000-4 suite, DIN EN IEC 60747-17 (VDE 0884-17), and UL1577.
