Hot-selling and scarce LM2596SX-ADJ/NOPB Power Converter 150-kHz 3-A Step-Down Voltage Regulator TO-263 spot stock

    Product Descriptions

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 fixedfrequency oscillator.

The LM2596 series operates at a switching frequency  of 150 kHz, thus allowing smaller sized filter  components than what can 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.
