Image of Diodes' AL17050 High-Voltage Buck Converter Diodes' AL17050 is a high-voltage input step-down regulator that provides accurate constant voltage (CV) and outstanding dynamic performance without requiring an optocoupler over line and load regulation. It works with a single winding inductor, and the integrated 500 V MOSFET 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 through variable switching frequency as load changes. The device has rich protection features such as OTP, OSP, OLP, and OLD. The AL17050 is available in the TSOT25 package.

Features
Integrated 500 V/30Ω MOSFET to support high-voltage input Requires few external components to provide a constant voltage power supply for MCU or other ZigBee/BLE devices Input voltage range from 90 V_ACto 264 V_AC A wide range of input voltages are supported to meet requirements from a broad spectrum of applications		Better power efficiency and lower standby power The max peak current and switching frequency will decrease if the load decreases, thus reaching low standby power Built-in protections against anomalies for a reliable system Over-temperature protection, output short protection, over-load protection, and open loop detection enhance the system safely
Applications
Connected lighting IoT devices		Home appliances
