FEATURES  
DESCRIPTION  
The LM2594/LM2594HV series of regulators are  
monolithic integrated circuits that provide all the  
active functions for a step-down (buck) switching  
2345  
3.3V, 5V, 12V, and Adjustable Output Versions  
Adjustable Version Output Voltage Range,  
1.2V to 37V (57V for the HV Version)±4% Max  
Over Line and Load Conditions  
regulator, capable of driving  
a 0.5A 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, and are packaged  
in a 8-lead PDIP and a 8-lead surface mount SOIC  
package.  
Available in 8-pin Surface Mount SOIC and  
PDIP-8 Package  
Ensured 0.5A Output Current  
Input Voltage Range up to 60V  
Requiring

components, these regulators are simple to use and  
feature internal frequency compensation†, a fixed-  
frequency oscillator, and improved line and load  
regulation specifications.  
Low Power Standby Mode, IQ typically 85 μA  
High Efficiency  
The LM2594/LM2594HV 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. Because of  
its high efficiency, the copper traces on the printed  
circuit board are normally the only heat sinking  
needed.  
Uses Readily Available Standard Inductors  
Thermal Shutdown and Current Limit  
Protection  
APPLICATIONS  
A standard series of inductors (both through hole and  
surface mount types) are available from several  
different manufacturers optimized for use with the  
LM2594/LM2594HV series. This feature greatly  
simplifies the design of switch-mode power supplies.  
Simple High-efficiency Step-down (Buck)  
Regulator  
Efficient Pre-regulator for Linear Regulators  
On-card Switching Regulators  
Positive to Negative Convertor  
Other features include an ensured ±4% tolerance on  
output voltage under all conditions of input voltage  
and output load conditions, and ±15% on the  
oscillator frequency. External shutdown is included,  
featuring typically 85 μA standby current. 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.  
The LM2594HV is for applications requiring an input  
voltage up to 60V.
