FEATURES  
DESCRIPTION  
The LM2599 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.

Adjustable Version Output Voltage Range,  
1.2V to 37V ±4% Max Over Line and Load  
Conditions  
•
•
Ensured 3A Output Current  
Available in 7-Pin TO-220 and TO-263 (Surface  
Mount) Package  
This series of switching regulators is similar to the  
LM2596 series, with additional supervisory and  
performance features added.

Input Voltage Range Up to 40V  
150 kHz Fixed Frequency Internal Oscillator  
Shutdown/Soft-start  
Requiring  
a
minimum number of external  
components, these regulators are simple to use and  
include internal frequency compensation†, improved  
line and load specifications, fixed-frequency oscillator,  
Shutdown/Soft-start, error flag delay and error flag  
output.

Low Power Standby Mode, IQ Typically 80 μA  
High Efficiency  
The LM2599 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 7-lead TO-220 package with several  
different lead bend options, and a 7-lead TO-263  
Surface mount package.  
APPLICATIONS  
•
Simple High-Efficiency Step-down (Buck)  
Regulator  
A standard series of inductors (both through hole and  
surface mount types) are available from several  
different manufacturers optimized for use with the  
LM2599 series. This feature greatly simplifies the  
design of switch-mode power supplies.  
•
•
•
Efficient Pre-Regulator for Linear Regulators  
On-Card Switching Regulators  
Positive to Negative Converter  
Other features include an ensured ±4% tolerance on  
output voltage under all conditions of input voltage  
and output load conditions, and ±15% on the  
oscillator frequency. External shutdown is included,  
featuring typically 80 μA standby current. Self  
protection features include a two stage current limit  
for the output switch and an over temperature  
shutdown for complete protection under fault
