It is LM2596 DC-DC Buck Converter with voltage rating 4.5-40V to 3-35V. This step down power module is adjustable with a potentiometer. RoboticsBD

Features:

  1. Adjustment method: first correct input power (between 4.5-50V) then multimeter to monitor the output voltage and adjust potentiometer (usually clockwise turn boost, buck turn counterclockwise),
  2. Input: IN+ input positive IN- input negative
  3. Output: OUT+ output positive OUT- output negative
  4. Static power consumption is only about 6mA. RoboticsBD
  5. Connection: Welding, plus pin can be directly soldered after the PCB.
  6. Short circuit protection: current limiting, thermal protection, self-recovery.
  7. Non-isolated step-down (BUCK) switching regulator.
  8. Short circuit protection: Current limiting, self-recovery
  9. Potentiometer adjustment direction is as Clockwise (increase) and Anti-clockwise (decrease)
  10. Non-synchronous rectification. RoboticsBD
