This DC-DC switching buck converter is capable of driving a 5A load with excellent line and load regulation. The main switching component is XL4015, an adjustable output version switching regulator. It is an efficient switching regulator and the output efficiency is significantly higher in comparison with the popular step down regulators. At higher input voltages, the regulator operates at a switching frequency of 180kHz, thus allowing the overall board size to be smaller and space-saving. It is a high-power switching module with a toroidal ring inductor.
Input Voltage: 4 ~ 38V
Output Voltage: 1.25 ~ 32V (adjustable)
Output Current: 5A (Max.)
Note: The higher the voltage, the load current increases. Try to use it within 4.5A.
Output Current: 0-5A (it is recommended to use within 4.5A)
Output Power: 75W
Working Temperature: -40 ~ +85°C
Working Frequency: 180KHz
Conversion Efficiency: up to 96% (efficiency is related to input, output voltage, current, and pressure difference)
Load Regulation Rate: S ( I ) ≤ 0.8%
Voltage Adjustment Rate: S ( u ) ≤ 0.8%
Protection: Short circuit Protection, Over-temperature protection
