Specifications at a glance Model: LM2596HV voltage regulator module Maximum output voltage: 50V Input voltage range (working): DC 550V Maximum output power: 15W Indicators: Indicative LED driver and constant current charging indicator Applications and use scenarios Scenario 1: Powering microcontroller and sensor projects from a vehicle or highervoltage battery. Input from 12V24V DC sources can be stepped down to 5V or other stable voltages for logic circuits and peripherals. Scenario 2: Supplying midrange loads in hobbyist electronics, such as RC receivers, small displays, or microcontroller boards, from a single 9V–36V supply, with adjustable output to match device requirements. Scenario 3: Battery charging and constantcurrent applications. Use the module in charging circuits where a constantcurrent indicator is helpful for monitoring charging progress and adjusting charging current within the module's capabilities. Notes Ensure the input voltage remains within 550V DC and the output load does not exceed the 15W maximum to avoid overheating or damage. Adjust the output voltage with the appropriate control (potentiometer) while monitoring with a suitable voltmeter to achieve the desired target voltage. Use appropriate safety precautions when working with higher voltages and power sources.
