DIODES AL17050WT-7

The AL17050 is a universal AC high voltage input step down regulator that provides accurate constant voltage (CV) and outstanding dynamic performance without requiring an opto - coupler over line and Load regulation. Typical applications are offline low power applications including home appliance applications and IoT applications. Working with a single winding inductor and integrating a 500V MOSFET internal can make it use fewer external components and create a low Bill Of Material (BOM) cost solution. The AL17050 achieves excellent regulation and high power efficiency. The characteristics of max peak current and driving frequency vary as the load change can get excellent efficiency performance at light load and improve the overall average efficiency. The AL17050 has rich protection features to enhance the system safety and reliability. It has Over Temperature Protection, VCC Under Voltage Lock function, Output Short Protection, Over Load Protection and Open Loop Protection. The AL17050 is available in the SOT25 package.
