DIODES Incorporated Integrated Circuits (ICs) - Power Management (PMIC) - AC DC Converters, Offline Switches AP3917BS7-13

The AP3917BS7-13 is a universal AC voltage input step-down power switcher designed for home appliances and IoT applications. It features a non-isolated buck or offline flyback solution and integrates a high-performance 650V Power MOSFET, which allows for a reduced number of external components and a lower Bill of Materials (BOM) cost. The device operates efficiently across a wide input range of 85VAC to 300VAC, with a maximum output current of 170mA and a typical peak current of 280mA. This converter is engineered for high power efficiency, with performance improvements at light loads due to its peak current and switching frequency reduction. It includes multiple protection features such as over-temperature protection, under-voltage lockout, output short protection, overload protection, and open-loop protection, enhancing system safety and reliability. The AP3917BS7-13 is packaged in an SO-7 format and is compliant with RoHS standards, making it suitable for environmentally conscious designs.
