Diodes Incorporated introduces the AP3927D, a universal AC-DC offline regulator with low standby power, which is specially designed for IoT applications and home appliances with a non-isolated buck solution or buck-boost solution.
The device integrates the controller and a 700V high-performance power MOSFET into one monolithic device. Coordinating with a single-winding inductor, it uses minimum external components and provides a low Bill Of Material (BOM) cost solution. The AP3927D supports fixed frequency CCM mode with heavy load, and PFM (Pulse-Frequency Modulation) operation at light load. Since the peak current is very low for light-load operation, it ensures an excellent audible noise-free performance.
The AP3927D has multiple protection features to enhance the system's safety and reliability, which include overtemperature protection, undervoltage lockout function, output short protection, and overload protection. It is available in SO-7 (Type B) package.
