Description

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.
