AP3927D HIGH-PERFORMANCE AC-DC OFFLINE REGULATOR Description The AP3927D is a universal AC/DC offline regulator with low standby power, which is specially designed for IoT applications and home appliances with non-isolated buck solution or buck-boost solution. Pin Assignments (Top View) The device integrates the controller and a 700V high-performance power MOSFET into one monolithic device. Coordinating with a singlewinding inductor, it uses minimum external components and provides a low Bill Of Material (BOM) cost solution. BP 1 FB 2 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.
