AP3917C
UNIVERSAL AC VOLTAGE STEP DOWN POWER SWITCHER Description Pin Assignments The AP3917C is a universal AC voltage step-down power switcher,
which is specially designed for home appliance and IoT applications
with non-isolated buck solution or offline flyback solution. (Top View) NEW PRODUCT 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 AP3917C can achieve excellent regulation and high power
efficiency. The peak current and switching frequency continuously
reduce as the load decreases, so it can get excellent efficiency
performance at light load and improve the overall system efficiency.
The AP3917C has multiple protection features to enhance the system
safety and reliability. It has over temperature protection, undervoltage lock function, output short protection, overload protection, and
open-loop protection.
The AP3917C is available in the SO-7 package.  Universal 85VAC to 265VAC Input Range 
