Power Integrations High Voltage Switcher 6.5 A, 24V, 75W, Flyback Topology, Surface Mount InSOP-24D INN4073C-H186-TL

Power Integrations INN4073C-H186-TL is a high voltage switcher IC designed for efficient flyback power converters delivering up to 75 W output power with maximum output current of 6.5 A and output voltage up to 24 V. Packaged in a surface mount InSOP-24D form factor, it integrates primary and secondary controllers alongside safety-rated feedback to enable compact and reliable power supply designs.

The IC supports zero voltage switching with switching frequencies reaching up to 140 kHz, effectively minimizing transformer size and improving power density. It includes a synchronous rectification driver and allows for precise output current sensing via an external resistor, enhancing output regulation and efficiency.

Designed for industrial, electronic component manufacturing, and power management applications, the INN4073C-H186-TL includes multiple protective features such as output overvoltage and overcurrent limiting, as well as thermal shutdown to ensure safe operation under various conditions. It operates over a broad temperature range from -40°C to 150°C, making it suitable for harsh operating environments.

This device forms part of the InnoSwitch4-CZ series, pairing with Clamp Zero active clamp ICs to further enhance efficiency and reduce electromagnetic interference in flyback converters. Its compact dimensions (length 9.4mm, width 1.6mm, height 10.8mm) facilitate integration into space-constrained designs.
