Frequently Asked Questions
What is LM2596?
The LM2596 is a commonly used popular step-down switching regulator IC. The adjustable version can take in input voltage from 4.5V to 40V and convert it to variable voltage sourcing upto of 3A of continues current. Because of its high current capability is commonly used in power modules to power/control heavy loads.
What is the difference between LM2576 and LM2596?
LM2596 is an upgraded version of LM2576. The small size of capacitors and inductors can make the size of the switching power supply smaller, but LM2576 also has the advantage of less switching loss and less interference. 2596 has high power consumption because of high frequency.
How to use LM2596?
The LM2596 is not difficult to use because it requires very minimum number of components. The unregulated voltage is given to pin 1 (Vin) across a filter capacitor to reduce input noise. The ON/OFF or enable pin (pin 5) would be connected to ground to enable the IC. If made high the IC will enter shutdown mode and prevent leakage current. This feature will be useful to save input power when operating via battery. The feedback pin is a important pin that sets the output voltage. It senses the output voltage and is based on the value of this output voltage the switching frequency of the internal switch is adjusted to provide the desired output voltage. Finally the output voltage is obtained through pin 2 through an LC filter.
