The DC-DC Buck Converter Step Down Module LM2596 Power Supply is a versatile step-down (buck) switching regulator renowned for its ability to drive a 3-A load while maintaining excellent line and load regulation. Available in fixed output voltages of 3.3 V, 5 V, 12 V, and an adjustable version, it offers flexibility to suit various applications.

Operating at a switching frequency of 150kHz, the LM2596 series allows for smaller sized filter components compared to regulators with lower switching frequencies. This feature contributes to compact designs without compromising performance.

Equipped with a high-precision potentiometer, this LM2596 DC-DC buck converter module efficiently drives loads up to 3A with precision. Compatible with Freeduino UNO, other mainboards, and basic modules, it offers broad compatibility for diverse projects. For loads exceeding 2.5A or 10W, the addition of a heat sink is recommended to ensure optimal performance.

Internally compensated, this device minimizes the need for external components, simplifying power supply design and implementation. Its switch-mode operation delivers significantly higher efficiency compared to conventional three-terminal linear regulators, particularly with higher input voltages.

In summary, the LM2596 Buck Converter stands out for its efficiency, compactness, and versatility, making it a preferred choice for a wide range of electronic applications.
