POWER INTEGRATIONS INN3276CH203TL Flyback Controller IC
The InnoSwitch™ 3-CP family of integrated circuit (IC) controllers simplifies the design and manufacturing of flyback power converters, especially those requiring high efficiency and compact size. These ICs combine primary and secondary controllers with safety-rated feedback into a single device, offering protections such as line overvoltage and undervoltage, output overvoltage, overcurrent limiting, and overtemperature shutdown. Equipped with a quasi-resonant (QR) / continuous conduction mode (CCM) flyback controller, a high-voltage switch, secondary-side sensing, and a synchronous rectification driver, these devices support continuous adjustment of output current and voltage for constant power profiles. They are suitable for applications including high-efficiency flyback power supplies up to 100W and various charger protocols such as USB Power Delivery (PD), Quick Charge (QC), and proprietary methods. Features include energy-efficient operation with up to 94% efficiency, integrated safety and protection features, accurate voltage and current regulation, reinforced isolation greater than 4000VAC, and low no-load power consumption below 30mW. Available in different configurations supporting latching and auto-restart behaviors for various applications, these modules are UL1577 and TUV safety approved.
