AP3917BS7-13 Universal AC Voltage Step Down Power Switcher – SO-7 Package
The AP3917B is a universal AC voltage input step-down power switcher, which is specially designed for home appliances and IoT applications, with a non-isolated buck solution or offline flyback solution. The device integrates a 650V high-performance Power MOSFET. Coordinating with a single-winding inductor, it uses fewer external components and provides a low Bill Of Material (BOM) cost solution. The AP3917B 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 AP3917B has multiple protection features to enhance system safety and reliability. It has over-temperature protection, an Undervoltage lock function, output short protection, overload protection, and open-loop protection.
