XL7015 DC-DC Step Down Adjustable Power Supply Buck Module

The XL7015 DC-DC Step Down Adjustable Power Supply Buck Module is a compact and efficient power solution designed to convert higher input voltages to stable, lower outputs with minimal ripple and superior performance. With a fixed frequency of 150 kHz, this buck converter can deliver up to 0.8A output current, making it ideal for electronics enthusiasts and professional applications alike.

Powered by the XL7015 PWM control IC, this module supports a wide input range from 1.25V to 20V and features adjustable output voltage, allowing for flexible use in a variety of DC conversion scenarios. It excels in powering devices such as LED lights, LCD screens, portable instruments, telecom/networking equipment, and industrial electronics, particularly when reducing 12V or 24V input to standard voltages like 5V or 3.3V.

Built-in features like thermal shutdown, current limiting, and short circuit protection make this module a reliable choice for long-term and safe operation.

Applications :

1. Use as a step-down module.

1. Adjust the “voltage potentiometer” so that the output voltage reaches the value you want.

2. Use as a LED constant current driver module

1. Adjust the “voltage potentiometer” so that the output voltage reaches the value you want.
2. Use a multimeter to measure the output short-circuit current, while regulating the “current potentiometer” so that the output current reaches a predetermined LED operating current.
3. Connect LED, work.

(1,2 steps as Output is unloaded, do not connect LED)
