General 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 3A load with excellent line and load regulation.
These devices are available in fixed output voltages of 3.3V, 5V, 12V, 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 needed with lower frequency switching regulators. Available in a standard 5-
lead TO-220 package with several different lead bend options, and a 5-lead TO-263 surface mount package.
A standard series of inductors are available from several different manufacturers optimized for use with the
LM2596 series. This feature greatly simplifies the design of switch-mode power supplies.
Other features include a guaranteed ±4% tolerance on output voltage under specified input voltage and
output load conditions, and ±15% on the oscillator frequency. External shutdown is included, featuring
typically 80 A standby current. Self protection features include a two stage frequency reducing current limit
for the output switch and an over temperature shutdown for complete protection under fault conditions.
