AP3917B UNIVERSAL AC VOLTAGE STEP DOWN POWER SWITCHER Description Pin Assignments
The AP3917B is a universal AC voltage input step-down power
(Top View)
switcher, 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. S 3 6 FB The AP3917B can achieve excellent regulation and high power efficiency. The peak current and switching frequency continuously S 4 5 BP reduce as the load decreases, so it can get excellent efficiency performance at light load and improve the overall system efficiency. The AP3917B has multiple protection features to enhance the system
SO-7
safety and reliability. It has over temperature protection, under- voltage lock function, output short protection, overload protection, and
Applications
open-loop protection. Non-Isolated Home Appliances: AC Fans, Rice Cookers, Shavers; Milk Machines The AP3917B is available in the SO-7 package. IoT Applications Industrial Controls
Features
Standby and Auxiliary Universal 85V AC to 265VAC Input Range Internal MOSFET of 650V Maximal Peak Current: 280mA Typical Improved Constant Voltage: ±5% Maximum 170mA Rated Output Current No Load Power Consumption: < 30mW with External Bias Frequency Modulation to Suppress EMI Various Protections: OTP (Over Temperature Protection), OLP (Overload 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.
