General Description

The LM2596 seriesof regulators are monolithic integrated
circuits that provideallthe active functionsfora step-down
(buck) switching regulator, capableof drivinga3A load with
excellent line and load regulation. These devices are avail-
ablein fixed output voltagesof 3.3V,5V, 12V, andan adjust-
able output version.
Requiringa minimum numberof external components, these
regulators are simpleto use and include internal frequency
compensation†, anda fixed-frequency oscillator.
The LM2596 series operatesata switching frequencyof
150 kHz thus allowing smaller sized filter components than
what wouldbe needed with lower frequency switching regu-
lators. Availableina standard 5-lead TO-220 package with
several different lead bend options, anda 5-lead TO-263
surface mount package. standard seriesof inductors are available from several
different manufacturers optimizedfor use with the LM2596
series. This feature greatly simplifies the design of
switch-mode power supplies.
Other features includea guaranteed ±4% toleranceon out-
put voltage under specified input voltage and output load
conditions, and ±15%on the oscillator frequency. External
shutdownis included, featuring typically80μA standby cur-
rent. Self protection features includea two stage frequency
reducing current limit for the output switch andan over
temperature shutdownfor complete protection under fault
conditions.
Features
3.3V, 5V, 12V, and adjustable output versions Adjustable version output voltage range, 1.2Vto 37V
±4% max over line and load conditions Availablein TO-220 and TO-263 packages Guaranteed3A output load current Input voltage rangeupto 40V Requires only4 external components Excellent line and load regulation specifications 150 kHz fixed frequency internal oscillator TTL shutdown capability Low power standby mode,IQ typically80μA High efficiency Uses readily available standard inductors Thermal shutdown and current limit protection
Applications
Simple high-efficiency step-down (buck) regulator On-card switching regulators Positiveto negative converter
