AP3917B Datasheet Universal AC Voltage Step Down Power Switcher

Manufacturer: Diodes Incorporated

Overview: AP3917B UNIVERSAL AC VOLTAGE STEP DOWN POWER SWITCHER.

General Description

Pin Assignments The AP3917B is a universal AC voltage input 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) The device integrates a 650V high performance Power MOSFET.

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