The LM3151/2/3 SIMPLE SWITCHER® Controller is an easyto use and simplified step down power controller capable ofproviding up to 12A of output current in a typical applicaTIon.OperaTIng with an input voltage range from 6V-42V, theLM3151/2/3 features a fixed output voltage of 3.3V, and featuresswitching frequencies of 250 kHz, 500 kHz, and 750kHz. The synchronous architecture provides for highly efficientdesigns. The LM3151/2/3 controller employs a ConstantOn-TIme (COT) architecture with a proprietary Emulated RippleMode (ERM) control that allows for the use of low ESRoutput capacitors, which reduces overall soluTIon size andoutput voltage ripple. The Constant On-Time (COT) regulationarchitecture allows for fast transient response and requiresno loop compensation, which reduces external componentcount and reduces design complexity.
