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 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 transientresponse 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, shortcircuit 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’sWEBENCH 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.
