XL4015 5A DC-DC Voltage Step Down Buck Converter Price in Pakistan | AmpFlick

Description

Technical Specifications of XL4015 5A DC-DC Voltage Step Down Buck Converter

• Regulator Type: XL4015 switching buck regulator with internal power MOSFET.

• Input Voltage: Supports a wide range from 4V to 38V DC.

• Output Voltage: Continuously adjustable from 1.25V to 36V DC.

• Current Capacity: Maximum 5A output current with proper heat dissipation.

• Switching Frequency: High-frequency 180kHz operation for low output ripple.

• Conversion Efficiency: Delivers up to 96% energy transfer under optimal loads.

• Inductor: High-power toroidal ring inductor for stable magnetic flux.

Usage and Voltage Calibration

• First, connect the unregulated power source to the IN+ and IN- terminals.

• Next, use a multimeter to measure the voltage across the OUT terminals.

• Then, rotate the on-board multi-turn potentiometer to set your target voltage.

• Afterward, verify that the input voltage is always higher than the desired output.

• Consequently, this ensures the switching regulator maintains a steady, regulated current flow.

• Finally, connect your load only after confirming the precise output voltage settings.

Advantages and Disadvantages

• Pros: The XL4015 5A DC-DC Voltage Step Down Buck Converter offers massive 75W output power.

• Furthermore, it maintains significantly cooler operating temperatures than linear regulators like the LM7805.

• Cons: The module cannot increase voltage; it only steps down the input.

• Additionally, drawing more than 4.5A for long periods requires an external aluminum heatsink.

Precautions and What to Avoid

• Warning: Never reverse the positive and negative input polarities to prevent chip failure.

• Avoid short-circuiting the output terminals while operating at high input voltages.

• Do not exceed the 38V input limit to protect the onboard electrolytic capacitors.

What is Included in the Package

• 1x XL4015 5A DC-DC Voltage Step Down Buck Converter Module.

• 1x Self-adhesive mini aluminum heatsink for the XL4015 IC.

• Anti-static protective packaging for safe component transport.
