LM3150  
SIMPLE SWITCHER® CONTROLLER, 42V Synchronous  
Step-Down  
General Description  
Features  
The LM3150 SIMPLE SWITCHER® Controller is an easy to  
use and simplified step down power controller capable of pro-  
viding 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 syn-  
chronous 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 compensa-  
tion, which reduces external component count and reduces  
design complexity.

6V to 42V Wide input voltage range  
Adjustable output voltage down to 0.6V  
Programmable switching frequency up to 1 MHz  
No loop compensation required  
Fully WEBENCH® enabled  
Low external component count  
Constant On-Time control  
Ultra-fast transient response  
Stable with low ESR capacitors  
Output voltage pre-bias startup  
Valley current limit  
Programmable soft-start

Fault protection features such as thermal shutdown, under-  
voltage lockout, over-voltage protection, short-circuit protec-  
tion, 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 ex-  
ternal components and National’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, electri-  
cal simulation, thermal simulation, and Build-It boards for  
prototyping.
