THE AP3917D IS NOT RECOMMENDED FOR NEW DESIGNS. PLEASE USE THE AP3927D. AP3917D UNIVERSAL AC VOLTAGE STEP DOWN POWER SWITCHER Description Pin Assignments
The AP3917D is a universal AC voltage step-down power switcher,
(Top View)
which is specially designed for home appliances and IoT applications, with non-isolated buck solution or offline flyback solution. NC 1 7 Drain The device integrates a 700V high-performance Power MOSFET. NC 2 Coordinating with a single-winding inductor, it uses fewer external components and provides a low Bill of Material (BOM) cost solution. S 3 6 FB The AP3917D can achieve excellent regulation and high power efficiency. The peak current and switching frequency continuously S 4 5 BP reduce as the load decreases, thus receiving excellent efficiency performance at light load and improving the overall system efficiency.
SO-7
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.

Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
•
Halogen- and Antimony-Free. “Green” Device (Note 3)
•
For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100/101/200, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative. https://www.diodes.com/quality/product-definitions/
Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant. 2. See https://www.diodes.com/quality/lead-free/ for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free. 3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds.
