AL17050 Universal HV Step Down Converter Diodes Incorporated AL17050 Universal High Voltage (HV) Step Down Converter provides accurate Constant Voltage (CV) and performs without an optocoupler over the line and load regulation. This AL17050 step-down converter features 100µA low operation current, Under Voltage Lock Out (UVLO), open loop protection, output short protection, and Over Temperature Protection (OTP). The AL17050 step-down converter works with a single winding inductor, integrates a 500V internal MOSFET, and uses fewer external components. Typical applications include the Internet of Things (IoT), industrial controls, standby power, and home appliance applications.
