FEATURES  
DESCRIPTION  
The LM3150 SIMPLE SWITCHER® Controller is an  
easy to use and simplified step down power controller  
capable of providing up to 12A of output current in a  
typical application. Operating with an input voltage  
range of 6V-42V, the LM3150 features an adjustable  
output voltage down to 0.6V. The switching frequency  
is adjustable up to 1 MHz and the synchronous  
architecture provides for highly efficient designs. The  
LM3150 controller employs a Constant On-Time  
(COT) architecture with a proprietary Emulated Ripple  
Mode (ERM) control that allows for the use of low  
ESR output capacitors, which reduces overall solution  
size and output voltage ripple. The Constant On-Time  
(COT) regulation architecture allows for fast transient  
response and requires no loop compensation, which  
reduces external component count and reduces  
design complexity.

Fault protection features such as thermal shutdown,  
under-voltage lockout, over-voltage protection, short-  
circuit protection, current limit, and output voltage pre-  
bias startup allow for a reliable and robust solution.  
The LM3150 SIMPLE SWITCHER® concept provides  
for an easy to use complete design using a minimum  
number of external components and TI’s WEBENCH®  
online design tool. WEBENCH® provides design  
support for every step of the design process and  
includes features such as external component  
calculation with a new MOSFET selector, electrical  
simulation, thermal simulation, and Build-It boards for  
prototyping.
