Large current 5A constant current LED driver lithium-ion battery

product description
The module combines the efficient XMLSEMI XL4005 DC-DC step-down converter IC with the TI LM358 op amp for stable current regulation. This module provides higher efficiency than modules based on the LM2596 and XL4015, which means your device has less heat and more power available.
Maintains a stable output voltage and limits the output current in the input voltage range. Ideal for general voltage conversion, battery charging, powering of raw LEDs, automotive electronics, battery switching, microcontrollers and electronics.
Input Voltage: 5-32V DC, Output Voltage: 0.8-30V DC, Maximum Load: 75W / 5A Peak, 50W / 3.5A Duration (whichever is lower, amps or watts)
Conversion efficiency: up to 95%, (our test results: 24V-> 12V1A: 92.7%)
The input must be at least 1V above the output voltage. Applying reverse polarity voltage to input or output may damage the module.
Size: 51x26.3x14mm, XL4005 IC, 300KHz switching frequency
