This XL4016E1 200W Step Down Power Supply Module with voltage rating 4-40VDC to 1.25-36VDC.This module is rated for a maximum power of 200W. The output current for the module can be increased to 8A with the addition of an external fan onto the heatsinks to cool the IC.

Note: This Product is available in two different variants (XL4016E1 and HW-674) with the same working, we will ship it randomly.


  1. Adjustment method: first correct input power (between 4-40V) 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.
  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
