LM2574, NCV2574  
0.5 A, Adjustable Output  
Voltage, Step−Down  
Switching Regulator  
The LM2574 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 0.5 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 LM2574 are offered by several  
different inductor manufacturers.

Since the LM2574 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 most cases, the power dissipated by the LM2574 regulator is so low,  
that the copper traces on the printed circuit board are normally the only  
heatsink needed and no additional heatsinking is required.

The LM2574 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 60 mA (typical) standby current. The  
output switch includes cycle−by−cycle current limiting, as well as  
thermal shutdown for full protection under fault conditions.
