FEATURES  
DESCRIPTION  
The LM3151/2/3 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 from 6V-42V, the LM3151/2/3 features a fixed  
output voltage of 3.3V, and features switching  
frequencies of 250 kHz, 500 kHz, and 750 kHz. The  
synchronous architecture provides for highly efficient

designs. The LM3151/2/3 controller employs  
Constant On-Time (COT) architecture with  
a
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.  
Programmable Soft-start  
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 LM3151/2/3 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.
