Power this LM2596 step-down (buck) DC-DC power converter module with any voltage from 4V to 40V. The output is adjustable via the on-board potentiometer from 1.25V to 35V at up to 3A maximum current.
This DC-DC converter is ideal for regulating 12V, 18V or 24V battery voltage down to the 12V, 9V, 5V or 3.3V levels required by many electronic circuits. For example, it could step a 12V car battery down to 5V for USB-powered devices such as cell phones or Arduino microcontrollers.
