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 ensured ±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 80μA
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. (1)
