LM 2596 Module Adjustable Output

The LM2596 Adjustable Buck Converter Module is a high-efficiency step-down (DC-DC) power supply module designed to convert a higher DC voltage to a stable, lower adjustable output voltage. Built around the reliable LM2596 switching regulator IC, this module can deliver up to 3A output current with excellent efficiency and thermal performance.

It features an onboard multi-turn potentiometer for precise voltage adjustment, making it ideal for power supply projects, embedded systems, battery-powered devices, and DIY electronics.
