DESCRIPTION  
ORDERING INFORMATION  
The LM2596 series of regulators are monolithic integrated  
circuits ideally suited for easy and convenient design of a  
step-down switching regulator(buck converter).  
All circuits of this series are capable of driving a 3.0A load  
with excellent line and load regulation. These devices are  
available in fixed output voltages of 3.3V, 5.0V,12V,  
and an adjustable output version.

These regulators were designed to minimize the number of external components to simplify the  
power supply design. Standard series of inductors optimized for use with the LM2596 are offered  
by several different inductor manufacturers.  
Since the LM2596 converter is a switch-mode power supply, its efficiency is significantly higher in  
comparison with popular three-terminal limear regulators, especially with higher input voltages.  
In many cases, the power dissipated is so low that no heatsink is required or its size could  
be reduced dramatically. A standard series of inductors optimized for use with the TJ2596 are  
available from several different manufacturers. This feature greatly simplifies the design of  
switch-mode power supplies. The LM2596 features include a guaranteed +/- 4% tolerance  
on output voltage within specified input voltages and output load conditions, and +/-15% on the  
oscillator frequency (+/- 2% over 0℃ to 125℃).  
External shutdown is included, featuring 80㎂ (typical) standby current. Self protection features include  
a two stage frequency reducing current limit for output switch and an over temperature shutdown for complete  
protection under fault conditions.
