LM2595  
SIMPLE SWITCHER® Power Converter 150 kHz  
1A Step-Down Voltage Regulator  
General Description  
Features  
n 3.3V, 5V, 12V, and adjustable output versions  
The LM2595 series of regulators are monolithic integrated  
circuits that provide all the active functions for a step-down  
(buck) switching regulator, capable of driving a 1A 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.  
n Adjustable version output voltage range, 1.2V to 37V  
±
4% max over line and load conditions  
n Available in TO-220 and TO-263 (surface mount)  
packages  
n Guaranteed 1A output load current  
n Input voltage range up to 40V  
n Requires only 4 external components  
n Excellent line and load regulation specifications  
n 150 kHz fixed frequency internal oscillator  
n TTL shutdown capability  
n Low power standby mode, IQ typically 85 µA  
n High efficiency  
Requiring a minimum number of external components, these  
regulators are simple to use and include internal frequency  
compensation , and a fixed-frequency oscillator.  
The LM2595 series operates at a switching frequency of  
150 kHz thus allowing smaller sized filter components than  
what would be needed with lower frequency switching regu-  
lators. Available in a standard 5-lead TO-220 package with  
several different lead bend options, and a 5-lead TO-263  
surface mount package. Typically, for output voltages less  
than 12V, and ambient temperatures less than 50˚C, no heat  
sink is required.  
n Uses readily available standard inductors  
n Thermal shutdown and current limit protection  
Applications  
A standard series of inductors are available from several dif-  
ferent manufacturers optimized for use with the LM2595 se-  
ries. This feature greatly simplifies the design of  
switch-mode power supplies.  
n Simple high-efficiency step-down (buck) regulator  
n Efficient pre-regulator for linear regulators  
n On-card switching regulators  
±
Other features include a guaranteed 4% tolerance on out-  
n Positive to negative converter  
put voltage under specified input voltage and output load  
Note: Patent Number 5,382,918.  
±
conditions, and 15% on the oscillator frequency. External  
shutdown is included, featuring typically 85 µA stand-by cur-  
rent. Self protection features include a two stage frequency  
reducing current limit for the output switch and an over tem-  
perature shutdown for complete protection under fault condi-  
tions.
