Description

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.

The XL4016E1 Step Down Power Supply Module is a high-efficiency DC-DC buck converter capable of delivering up to 200W output power with an adjustable voltage range. Designed using the XL4016E1 chip, this module supports wide input voltages (typically 8V–36V) and can output a stable voltage from 1.25V to 36V, making it ideal for powering Arduino boards, LED strips, battery chargers, solar systems, and more.

With high conversion efficiency (up to 96%), built-in thermal protection, and overcurrent safeguards, the module is robust enough for DIY electronics, embedded systems, and industrial automation use. The onboard potentiometer allows easy fine-tuning of the output voltage.

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


Applications

• DIY power supply units
• Battery charging circuits
• LED strip dimming and regulation
• Robotics and embedded electronics
• Solar power regulation and conversion
• Automotive 12V/24V to lower-voltage device power

Features:

  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
