LM2594  
0.5 A, Step-Down Switching  
Regulator  
The LM2594 regulator is monolithic integrated circuit ideally suited  
for easy and convenient design of a step−down switching regulator  
(buck converter). It is capable of driving a 0.5 A load with excellent  
line and load regulation. This device is available in adjustable output  
version. It is internally compensated to minimize the number of  
external components to simplify the power supply design.  
Since LM2594 converter is a switch−mode power supply, its  
efficiency is significantly higher in comparison with popular  
three−terminal linear regulators, especially with higher input voltages.  
The LM2594 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  
8−Lead PDIP and 8−Lead Surface Mount packages.

The other features include a guaranteed $4% tolerance on output  
voltage within specified input voltages and output load conditions, and  
$15% on the oscillator frequency. External shutdown is included,  
featuring 50 mA (typical) standby current. Self protection features  
include switch cycle−by−cycle current limit for the output switch, as  
well as thermal shutdown for complete protection under fault  
conditions.
