EASY SWITCHER  
3.0 A STEP–DOWN  
VOLTAGE REGULATOR  
The LM2576 series of regulators are monolithic integrated circuits ideally  
suited for easy and convenient design of a step–down switching regulator  
(buck converter). All circuits of this series are capable of driving a 3.0 A load  
with excellent line and load regulation. These devices are available in fixed  
output voltages of 3.3 V, 5.0 V, 12 V, 15 V, and an adjustable output version.  
These regulators were designed to minimize the number of external  
components to simplify the power supply design. Standard series of  
inductors optimized for use with the LM2576 are offered by several different  
inductor manufacturers.  
Since the LM2576 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. In many cases, the power  
dissipated is so low that no heatsink is required or its size could be reduced  
dramatically.

A standard series of inductors optimized for use with the LM2576 are  
available from several different manufacturers. This feature greatly simplifies  
the design of switch–mode power supplies.  
The LM2576 features include a guaranteed ±4% tolerance on output  
voltage within specified input voltages and output load conditions, and ±10%  
on the oscillator frequency (±2% over 0°C to 125°C). External shutdown is  
included, featuring 80 µA (typical) standby current. The output switch  
includes cycle–by–cycle current limiting, as well as thermal shutdown for full  
protection under fault conditions.
