The MIC28515 is an adjustable frequency, synchronous buck regulator that features a unique adaptive on-time control architecture. The MIC28515 operates over an input supply range of 4.5V to 75V, and provides a regulated output of up to 5A of output current. The output voltage is adjustable down to 0.6V with an accuracy of ±1%. The MIC28515 off ers a "Mode" select pin allowing the user to choose between Hyper Light load and Hyper Speed control operations.
