The ADIY LM2596 Buck Converter module is a versatile and easy-to-use step-down DC-DC converter with an adjustable output voltage. It boasts a wide input voltage range of up to 40V, making it suitable for various applications. The output voltage can be precisely adjusted using the onboard potentiometer. This module is capable of delivering up to 3A of DC load current with excellent line and load regulation. For currents exceeding 2A, the use of a heat sink is recommended to ensure optimal performance and thermal management.
