FEATURES  
DESCRIPTION  
The LM2574 series of regulators are monolithic  
23  
•
3.3V, 5V, 12V, 15V, and Adjustable Output  
Versions  
integrated circuits that provide all the active functions  
for a step-down (buck) switching 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, 15V, and an adjustable  
output version.  
•
Adjustable Version Output Voltage Range,  
1.23V to 37V (57V for HV version) ±4% Max  
Over Line and Load Conditions  
•
•
Specified 0.5A Output Current  
Wide Input Voltage Range, 40V, up to 60V for  
HV Version  
Requiring  
a
minimum number of external  
components, these regulators are simple to use and  
include internal frequency compensation and a fixed-  
frequency oscillator.  
•
•
•
Requires Only 4 External Components  
52 kHz Fixed Frequency Internal Oscillator  
The LM2574 series offers  
a
high-efficiency  
TTL Shutdown Capability, Low Power Standby  
Mode  
replacement for popular three-terminal linear  
regulators. Because of its high efficiency, the copper  
traces on the printed circuit board are normally the  
only heat sinking needed.  
•
•
•
High Efficiency  
Uses Readily Available Standard Inductors  
Thermal Shutdown and Current Limit  
Protection  
A standard series of inductors optimized for use with  
the LM2574 are available from several different  
manufacturers. This feature greatly simplifies the  
design of switch-mode power supplies.  
APPLICATIONS  
Other features include a specified ±4% tolerance on  
output voltage within specified input voltages and  
output load conditions, and ±10% on the oscillator  
frequency. External shutdown is included, featuring  
50 μA (typical) standby current. The output switch  
includes cycle-by-cycle current limiting, as well as  
thermal shutdown for full protection under fault  
conditions.  
•
Simple High-Efficiency Step-Down (Buck)  
Regulator

•
Efficient Pre-Regulator for Linear Regulators  
On-Card Switching Regulators  
Positive to Negative Converter (Buck-Boost)  
Typical Application (Fixed Output Voltage Versions)
