MIC28515T-E/PHA

DC-DC开关降压稳压器, 可调, 800 kHz, 4.5V-75V输入, 600 mV-32V/5 A输出, VQFN-32

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.
