The AP3928 is a universal AC voltage step-down power switcher, specially designed for home appliances and IoT applications with non-isolated buck solution.
The device integrates a 700V high-performance power MOSFET. Coordinating with a single-winding inductor, it uses fewer external components and provides a low bill of materials (BOM) cost solution.
The AP3928 can achieve high output current, excellent constant voltage regulation, and high conversion efficiency. The peak current and switching frequency continuously reduces as the load decreases, so the device can achieve excellent efficiency performance at light load and improve overall system efficiency.
The AP3928 has multiple protection features to enhance the system safety and reliability. The device has overtemperature protection, undervoltage lock function, output short protection, overload protection, and open-loop protection.
The AP3928 is available in the SO-8 (Standard) package.
