AP3917D Datasheet | Diodes Incorporated

UNIVERSAL AC VOLTAGE STEP DOWN POWER SWITCHER Description The AP3917D is a universal AC voltage step-down power switcher, which is specially designed for home appliances and Io T applications, with non-isolated buck solution or offline flyback solution. The device integrates a 700V high-performance Power MOSFET. Coordinating with a single-winding inductor, it uses fewer external ponents and provides a low Bill of Material (BOM) cost solution. The AP3917D can achieve excellent regulation and high power efficiency. The peak current and switching frequency continuously reduce as the load decreases, thus receiving excellent efficiency performance at light load and improving the overall system efficiency. The AP3917D has multiple protection Features to enhance the system safety and reliability. It has over-temperature protection, under-voltage lock function, output short protection, overload protection, and open-loop protection. The AP3917D is available in the SO-7 package.
