XL4015 Adjustable DC To DC Buck Converter





The XL4015 5A is the DC-DC Step-Down Buck Converter Module. XL4015  works as a 180KHz fixed frequency PWM buck (step-down) DC/DC module. XL4015 is capable of driving a 5A load with high efficiency, low ripple, and excellent line and load regulation. This 5A XL4015 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. It also works as a dedicated charger for Lithium Batteries (Li-Ion, LiPo) as it is capable of controlling voltage as well as current. Ex. 12V buck to 3.3V, 12V buck to 5V, 24V buck to 5V,24V buck to 12V, 36V buck to 24V, etc.
