Power Integrations, Inc. AC DC Converters, Offline Switches INN4074C-H185-TL

The INN4074C-H185-TL is an integrated offline CV/CC ZVS flyback switcher IC designed for high efficiency and compact power supply applications. It features a robust 750 V PowiGaN primary switch and operates with a steady-state switching frequency of up to 155 kHz, which helps minimize transformer size. The device supports both continuous conduction mode (CCM) and discontinuous conduction mode (DCM) with zero voltage switching (ZVS), enhancing efficiency up to 95% and reducing no-load consumption to less than 30 mW. This IC incorporates advanced protection features, including output overvoltage and undervoltage protection, over-current protection, and over-temperature protection. It also includes a synchronous rectification driver and secondary-side sensing for improved performance. The INN4074C-H185-TL is suitable for applications requiring high power density, such as USB PD adapters and high-efficiency power supplies, and complies with safety standards including UL1577 and TUV (EN62368-1). The device is packaged in an InSOP-24D format, ensuring ease of integration into various designs.
