UMW LM2596/LM2596HV  
3A Step-Down Voltage Regulator  
General Description  
Features  
The LM2596 /LM2596HV 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.  
n 3.3V, 5V, 12V, and adjustable output versions  
n Adjustable version output voltage range, 1.2V to 37V  
(57V for HV version)  
±
4% max over line and load conditions  
n Available in TO-220 and TO-263,TO-220B packages  
n Guaranteed 3A 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 80 µA  
n High efficiency  
n Uses readily available standard inductors  
n Thermal shutdown and current limit protection  
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 /LM2596HV series operates at a switching  
frequency of150 kHz thus allowing smaller sized filter com-  
pontents 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-lesd TO-262 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.  
Applications  
n Simple high-efficiency step-down (buck) regulator  
n On-card switching regulators  
n Positive to negative converter

Other features include a guaranteed 4% tolerance on out-  
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 80 µA standby cur-  
rent. 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.
