LM3151
Description
The LM3151/2/3 SIMPLE 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 k Hz, 500 k Hz, and 750 k Hz. 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 transient response and requires no loop pensation, which reduces external ponent count and reduces design plexity. Fault protection features such as thermal shutdown, undervoltage lockout, over-voltage protection, short-circuit protection, current limit, and output...
