XL4015 5A Adjustable DC-DC Buck Converter Module

The XL4015 5A Adjustable DC-DC Buck Converter Module is a high-current step-down power module for converting a higher DC input voltage into an adjustable lower output voltage. The common XL4015 module supports adjustable constant-voltage (CV) and constant-current (CC) operation, making it useful for powering electronics, driving LEDs and suitable battery-charging applications when configured correctly. Typical module specifications are around 4–38V input, 1.25–36V adjustable output and up to 5A output, with thermal conditions determining practical continuous power.
