FEATURES  
DESCRIPTION  
The LM5576 is an easy to use SIMPLE SWITCHER®  
buck regulator which allows design engineers to  
design and optimize a robust power supply using a  
minimum set of components. Operating with an input  
voltage range of 6 - 75V, the LM5576 delivers 3A of  
continuous output current with an integrated 170mΩ  
N-Channel MOSFET. The regulator utilizes an  
Emulated Current Mode architecture which provides  
inherent line regulation, tight load transient response,  
and ease of loop compensation without the usual  
limitation of low-duty cycles associated with current  
mode regulators. The operating frequency is  
adjustable from 50kHz to 500kHz to allow  
optimization of size and efficiency. To reduce EMI, a  
frequency synchronization pin allows multiple IC’s  
from the LM(2)557x family to self-synchronize or to  
synchronize to an external clock. The LM5576  
ensures robustness with cycle-by-cycle current limit,  
short-circuit protection, thermal shut-down, and  
remote shut-down. The device is available in a power  
enhanced HTSSOP-20 package featuring an  
exposed die attach pad for thermal dissipation. The  
LM5576 is supported by the full suite of WEBENCH®  
On-Line design tools.
