LM2599  
SIMPLE SWITCHER® Power Converter 150 kHz 3A  
Step-Down Voltage Regulator, with Features  
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 conditions.  
General 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 avail-  
able in fixed output voltages of 3.3V, 5V, 12V, and an adjust-  
able output version.  
Features  
n 3.3V, 5V, 12V, and adjustable output versions  
n Adjustable version output voltage range, 1.2V to 37V

max over line and load conditions  
This series of switching regulators is similar to the LM2596  
series, with additional supervisory and performance features  
added.  
n Guaranteed 3A output current  
n Available in 7-pin TO-220 and TO-263 (surface mount)  
Package  
n Input voltage range up to 40V  
n 150 kHz fixed frequency internal oscillator  
n 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 de-  
lay and error flag output.  
n Out of regulation error flag  
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.  
n Error output delay  
n Low power standby mode, IQ typically 80 µA  
n High Efficiency  
n Uses readily available standard inductors  
n Thermal shutdown and current limit protection  
A standard series of inductors (both through hole and sur-  
face mount types) are available from several different manu-  
facturers optimized for use with the LM2599 series. This fea-  
ture greatly simplifies the design of switch-mode power  
supplies.  
Applications  
n Simple high-efficiency step-down (buck) regulator  
n Efficient pre-regulator for linear regulators  
n On-card switching regulators  
n Positive to Negative converter  
±
Other features include a guaranteed 4% tolerance on out-  
put voltage under all conditions of input voltage and output
