LM2596S-ADJ Adjustable DC-DC step down buck converter Regulator SMD TO-263 3A IC 


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. 


3A Step Down Voltage Regulator IC
Available as 3.3V regulator, 5V Regulator, 12V Regulator and Variable regulator 
Input Supply Voltage: 4.5V to 40V
Minimum Output Voltage: 3.16V
Continuous Output Current: 3A
Peak Output Current: 6.9A
Switching Frequency: 150KHz
Available in To-220 and To-263 Package


The LM2596 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 3-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5 V, 12 V, and an adjustable output version. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation, and a fixed-frequency oscillator. 
The LM2596 series operates at a switching frequency of 150 kHz, thus allowing smaller sized filter components than what would be required with lower frequency switching regulators. Available in a standard 5-pin TO-220 package with several different lead bend options, and a 5-pin TO-263 surface mount package.
