This LM2596 Adjustable DC-DC Buck Step-Down Buck Power Supply (with Display) module uses the step-down switching regulator LM2596S to provide a stable power supply for powering your circuit. This can handle and adjust voltages from around 3-40V at 3Amps. The output voltage is adjustable and can ensure 3A output load current. It works at 150 kHz and has high efficiency >90%.
Features / Specification
