LM2596S & LM2577S DC-DC Adjustable Step-Up and step-down Power Supply Module
This is a buck-boost converter with an output voltage greater or less than the input voltage. Compared to linear regulators, DC/DC converters are primarily focused on efficiency and can achieve efficiencies of over 95% when boosted, thus reducing power consumption.
With this DC-DC Adjustable boost and buck voltage converter, you can change any other 3.5-28V power supply. The output voltage is adjusted from 1.25-26V. For example, your input voltage is 5V, you can adjust the output voltage from 1.25V to 26V any value. The max input and output rated current are 1A. This module integrates LM2596 and LM2577. It is very useful and easy to use. It would be a good assistant in your debugging. LM2596S + LM2577S dual chip. Step-up operation mode: Independent of the output voltage and input voltage (input for arbitrary values of 3.5V-28V output 1.25V-26V arbitrary value).

1. What is the function of LM2596S?
The LM2596S is an integrated circuit for step-down (buck) switching regulators that performs all the necessary active functions. It can efficiently power a 3-A load while maintaining outstanding line and load regulation. The adjustable version has an input voltage range of 4.5V to 40V. DC-DC power supply step-down modules frequently employ the LM2596S. The output capacitor of this IC serves two primary purposes: filtering the output and ensuring regulator loop stability.
2. What is the current of LM2596S?
The LM2596 is a step-down switching regulator with the capability to manage a maximum output load current of 3A.
