The XL4005 Adjustable Step-Down Power Supply Module is a high-performance DC-DC buck converter designed to deliver up to 5A output current. It has higher current capacity, improved efficiency, and enhanced power handling, making it ideal for DIY electronics, LED drivers, battery charging, and various power supply applications. Wide Input Voltage Range: Supports a broad DC input range, suitable for many power sources such as adapters, batteries, and solar panels. Adjustable Output Voltage: Onboard multi-turn potentiometer allows precise adjustment of output voltage to meet different project requirements. Specifications include a peak output current of 5A (Enhanced heat dissipation is required for operation above 3.5A), conversion efficiency of up to 90%, and a switching frequency of 300kHz. Module Type: Non-isolated step-down. Rectification Method: Asynchronous rectification. Input Voltage: DC 5V-32V. Output Voltage: DC 0.8V-24V. Output Ripple: 30mV (no-load). Load Regulation: ±0.5%. Voltage Regulation: ±2.5%. Due to different batches, there may be differences in product appearance and printed text, which will not affect use.
