The AP3917D is a universal AC voltage step-down power switcher, which is specially designed for home appliances and IoT 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 components and provides a low Bill of.
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.
