5V 3A LM2596 DC-DC Step-Down with USB

This DC-DC buck converter with the LM2596S-5.0 converts a DC voltage of 6 to 36 V into 5 V, available at two USB type A sockets. This allows USB devices to be run from a 12 V battery or a Raspberry Pi with OctoPrint to be powered directly from the power supply of a 3D printer.

Recommended alternative with an additional DC socket: 5V 3A LM2596 Dual DC-DC Step-Down with USB

Recommended Accessories:

• DC Socket Female Barrel Jack 5.5mm / 2.1mm with Screw Terminals
• 12V DC 4000mA Power Supply AC/DC Adapter 5.5mm/2.1mm Plug

Features:

• Fixed 5 V output voltage, chip LM2596S-5.0 according to the marking
• Two stacked USB type A sockets
• Power supply via screw terminal
• At high output current the switching regulator gets hot, provide air circulation for continuous load in an enclosure
