XL4015 (2) 5A Lithium Charger DC-DC Buck Converter Step-Down Power Module

The XL4015 is a high-efficiency DC-DC buck converter that is designed for stepping down higher DC voltages to a stable, lower output voltage. With a maximum output current of 5A, it is ideal for powering lithium battery chargers, or for use in other applications where a reliable, adjustable output voltage is needed. This module can convert input voltages ranging from 4V to 40V DC down to a stable, adjustable output from 1.25V to 36V. Its powerful 5A output capability makes it perfect for demanding applications, including battery-powered devices, solar power systems, and other high-current projects.

The XL4015 buck converter also comes with a lithium battery charging circuit, making it useful for charging Li-ion or LiPo batteries efficiently and safely. It includes features like overcurrent protection, short-circuit protection, and thermal shutdown to ensure safe operation in various environments.

Applications:

Use as a step-down modules with overcurrent protection capabilities.
Usage:

Adjust the “voltage potentiometer” so that the output voltage reaches the value you want.
Use a multimeter to measure the output short-circuit current with 10A stalls, while regulating the “current potentiometer” so that the output current reaches a predetermined overcurrent protection value. (For example, the meter displays the current value of 4A, then you can use the module to a maximum current of 4A)
Connected to the load.
Use as a battery charger.

Usage:

Make sure you need to charge the battery float voltage and charging current; (if lithium parameters 3.7V/2200mAh, then the float voltage is 4.2V, the maximum charging current 1C, ie 2200mA)
Under no-load conditions, adjust the “Voltage potentiometer” so that the output voltage reaches the float voltage; (if to 3.7V rechargeable lithium battery, the output voltage can be adjusted to 4.2V)
Use a multimeter to measure the output short-circuit current with 10A stalls, while regulating the “current potentiometer” so that the output current reaches a predetermined Charging current value.
Charge turn lamp current factory default is 0.1 times the charging current; (Battery during charging current is gradually reduced, if the charge current setting is 1A, then when the charge current is less than 0.1A, blue lights turned off, the green light is on, which means that the battery is fully charged)
Connected to the battery charge.
(1,2,3,4 steps as: Output is unloaded, do not connect the battery)
Use as a LED constant current driver module.
Usage:
Adjust the “voltage potentiometer” so that the output voltage reaches the value you want.
Use a multimeter to measure the output short-circuit current with 10A stalls, while regulating the “current potentiometer” so that the output current reaches a predetermined LED operating current.
Connect LED, work.
(1,2 steps as: Output is unloaded, do not connect LED)
