LM5575/LM5575Q  
SIMPLE SWITCHER® 75V, 1.5A Step-Down Switching  
Regulator  
General Description  
Features  
The LM5575 is an easy to use SIMPLE SWITCHER® buck  
regulator which allows design engineers to design and opti-  
mize a robust power supply using a minimum set of compo-  
nents. Operating with an input voltage range of 6 - 75V, the  
LM5575 delivers 1.5A of continuous output current with an  
integrated 330mΩ N-Channel MOSFET. The regulator uti-  
lizes 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 LM5575 guarantees robustness with cy-  
cle-by-cycle current limit, short-circuit protection, thermal  
shut-down, and remote shut-down. The device is available in  
a power enhanced TSSOP-16 package featuring an exposed  
die attach pad for thermal dissipation. The LM5575 is sup-  
ported by the full suite of WEBENCH® On-Line design tools.  
LM5575Q is an Automotive Grade product that is AEC-

Q100 grade 1 qualified (−40°C to + 125°C operating
