LM2575 & LM2576  
1A & 3A Miniconverter  
Switching Regulators  
POWER MANAGEMENT  
Description  
Features  
The LM2575/6 series switching regulators are monolithic  
integrated circuits designed for use in “buck” or “buck/  
boost” regulator applications requiring accurate output  
voltages over combined variations of line, load and  
temperature. This unique series greatly simplifies  
switching power supply design. The LM2575 has a  
maximum output current of 1A and the LM2576 is rated  
for 3A.  
u Pin for pin replacement for National’s LM2575/6  
series  
u DC-to-DC buck or buck/boost converter requiring  
only 4 support components  
u Fixed or adjustable voltages  
u Preset output voltages of 3.3V, 5V and 12V  
u Wide output voltage range, 1.23V to 35V  
u 82% typical efficiency @ 5V out  
u Wide input voltage range, 4V to 40V  
u Inhibit/enable control pin  
The LM2575/6 series miniconverters include a  
switching regulator and compensation network all within  
the same package. Just add a choke, catch diode and  
two capacitors to obtain an efficient DC-to-DC converter.  
The current limit and thermal shutdown features of the  
LM2575/6 series fully protect the device against  
overstress conditions.  
u Industrial temperature range  
u TO-220 and TO-263 packages  
Applications  
u Micro controller power supplies  
u Medical equipment  
u Industrial power supplies  
u Instrumentation power supplies  
The LM2575/6 series offers an alternative to popular 3  
terminal linear regulators by providing higher efficiency  
with reduced heatsink size. In many applications a heat  
sink will not be required.
