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 appliance 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. Coordinating with a single-winding inductor, it uses fewer external NC 2 components and provides a low Bill Of Material (BOM) cost solution.

performance at light load and improve the overall system efficiency.
R P
The AP3917D has multiple protection features to enhance the system
SO-7 W
safety and reliability. It has over temperature protection, under-

voltage lock function, output short protection, overload protection, and
N Applications
open-loop protection. Non-Isolated Home Appliances: AC Fans, Rice Cookers, Shavers; Milk Machines The AP3917D is available in the SO-7 package. IoT Applications Industrial Controls
Features
Standby and Auxiliary Universal 85VAC to 265VAC Input Range Internal MOSFET of 700V Maximal Peak Current: 500mA Typical Improved Constant Voltage: ±5% Maximum 300mA Rated Output Current No Load Power Consumption: < 30mW with External Bias Frequency Modulation to Suppress EMI Various Protections: OTP (Over Temperature Protection), OLP (Over Load Protection), SCP (Short Circuit Protection) Fewer Components Low Audible Noise Solution SO-7 Package
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3)
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.
