The LM2596 DC Constant Voltage and Constant Current Step-Downย Power Module is a versatile, efficient power supply module that provides adjustable output voltage (1.25V to 37V) and current. It uses the LM2596 buck converter for step-down voltage conversion, offering both constant voltage (CV) and constant current (CC) modes. The module includes an integrated LED voltmeter for real-time voltage monitoring, and its adjustable settings make it ideal for powering LEDs, batteries, and various electronics. It’s suitable for applications requiring precise voltage and current control, with input voltage typically ranging from 4V to 40V.
