LM2596 DC-DC Buck Converter Step-Down Power Supply Module

The LM2596 DC-DC Buck Converter Module is a high-efficiency step-down switching regulator designed to deliver stable output voltage with excellent line and load regulation. It is capable of driving loads up to 3A, making it suitable for a wide range of power supply applications.

The module operates at a switching frequency of 150kHz, allowing the use of smaller filter components compared to lower-frequency regulators. It is available in both fixed voltage versions (3.3V, 5V, 12V) and an adjustable output version for flexible voltage requirements.

This non-isolated constant voltage module uses non-synchronous rectification and includes built-in current limiting protection for short-circuit conditions. The output voltage can be adjusted using the onboard potentiometer.

The rated output current is 2A, with a maximum of 3A when an additional heatsink is used for proper thermal management.
