Hot-selling and scarce LM2596SX-3.3/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.
