Summary of Contents for AZ-Delivery XL4015
- Page 1 Welcome! Thank you for purchasing our AZ-Delivery Step Down Buck Converter XL4015 Module. On the following pages, we will introduce you to how to use and set-up this handy device. Have fun!
- Page 2 Areas of application The power supply is intended for use in electronic circuits, laboratories, educational institutions and development environ- ments. It is used to safely provide direct current for a variety of low-voltage applications. Required knowledge and skills Using the power supply requires basic knowledge of electrical engineering. Users should be able to safely assemble and ope- rate electrical circuits and take the necessary safety precautions.
- Page 3 Make sure the power supply is adequately ventilated during operation and monitor the temperature regularly. Caution: High temperatures can significantly shorten the lifespan of the power supply and connected devices. Note: Only operate the power supply within the recommended ambient temperatures (0°C to 40°C). Caution: Overheated components can cause fires. Note: Avoid use in direct sunlight or near heat sources.
- Page 4 A buck converter or the step down converter is a DC to DC power converter which steps down voltage from its input to its output while stepping up the current. It is a type of switched-mode power supply typically containing at least two semiconductors (a diode and a transistor), and at least one energy storage element, a capacitor or a inductor, or the two in combination.

Page 5: Specifications
» Internal Optimized Power MOSFET » Excellent line and load regulation The heart of this converter is the XL4015 integrated circuit, made by XLSEMI ("Shanghai Xinlong Semiconductor Technology Co.") The XL4015 integrated circuit is a 180kHz fixed frequency PWM* buck, or a step-down, DC to DC converter, capable of driving a 5A load with high efficiency, low ripple and excellent line and load regulation. - Page 6 Pinout of the converter There is one indicator LED onboard this converter that turns on when the converter is powered. As you can see on the images, there is a big coil onboard. Coils are big producers of the electromagnetic noise. Take this into consideration when you are designing the circuits that use radio signals, because this electromagnetic noise is a big source of reading errors.
- Page 7 Connecting the converter with other devices To connect the buck converter with any other device, first you have to set-up the output voltage of the converter to fit the needs of the other device. If you do not do that, you could easily destroy a device that you are connecting the converter to.
