SIMPLE SWITCHER 0.5A Step-Down Voltage Regulator  
General Description  
Features  
n 3.3V, 5V, 12V, 15V, and adjustable output versions  
The LM2574 series of regulators are monolithic 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.  
n Adjustable version output voltage range, 1.23V to 37V  
(57V for HV version) 4% max over line and load  
conditions  
n Guaranteed 0.5A output current  
n Wide input voltage range, 40V, up to 60V for HV version  
n Requires only 4 external components  
n 52 kHz fixed frequency internal oscillator  
n TTL shutdown capability, low power standby mode  
n High efficiency  
±
Requiring a minimum number of external components, these  
regulators are simple to use and include internal frequency  
compensation and a fixed-frequency oscillator.  
The LM2574 series offers a high-efficiency 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.  
n Uses readily available standard inductors  
n 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  
n Simple high-efficiency step-down (buck) regulator  
n Efficient pre-regulator for linear regulators  
n On-card switching regulators  
±
Other features include a guaranteed 4% tolerance on out-  
n Positive to negative converter (Buck-Boost)  
put voltage within specified input voltages and output load  
±
conditions, and 10% on the oscillator frequency. External  
shutdown is included, featuring 50 µA (typical) standby cur-  
rent. The output switch includes cycle-by-cycle current limit-  
ing, as well as thermal shutdown for full protection under  
fault conditions.  
Typical Application (Fixed Output Voltage Versions)
