AP3917C UNIVERSAL AC VOLTAGE STEP DOWN POWER SWITCHER Description Pin Assignments
The AP3917C is a universal AC voltage step-down power switcher,
(Top View)
which is specially designed for home appliance and IoT applications with non-isolated buck solution or offline flyback solution. NC 1 7 Drain The device integrates a 650V high performance Power MOSFET. Coordinating with a single-winding inductor, it uses fewer external NC 2 components and provides a low Bill Of Material (BOM) cost solution.
