The XL7015 DC-DC Step Down Adjustable Power Supply Buck Module is a 150 kHz fixed frequency PWM buck (step-down) DC/DC module, capable of driving a 0.8A load with high efficiency, low ripple, and excellent line and load regulation.

This product is a 150 kHz fixed frequency PWM buck (step-down) DC/DC module, capable of driving a 0.8A load with high efficiency,  low ripple, and excellent line and load regulation. 

The DC/DC buck module has applications where the input voltage is higher than the output voltage, such as battery, power transformer, DIY adjustable regulated power supply, LCD Monitor and LCD TV portable instrument power supply telecom/networking equipment, 24V vehicle notebook power supply, industrial equipment buck.

This module has an adjustable output Voltage. Ex. 12V buck to 3.3V, 12V buck to 5V, 24V buck to 5V,24V buck to 12V, etc.

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)

Features :

1. High efficiency up to 85%
2. The built-in thermal shutdown function
3. Built-in current limit function
4. In-Built output short protection function
5. Excellent Line and Load Regulation

Package Includes :

1 x XL7015 DC-DC Step Down Adjustable Power Supply Buck Module
