Part Number : MAX15108
Function : High-Efficiency, 8A, Current-Mode Synchronous Step-Down Switching Regulator
Manufacturers : Maxim Integrated
The MAX15108 high-efficiency, current-mode, synchronous step-down switching regulator with integrated power switches delivers up to 8A of output current. The regulator operates from 2.7V to 5.5V and provides an output voltage from 0.6V up to 95% of the input voltage,making the device ideal for distributed power systems,portable devices, and preregulation applications.
The IC utilizes a current-mode control architecture with a high gain transconductance error amplifier.
The current-mode control architecture facilitates easycompensation design and ensures cycle-by-cycle current limit with fast response to line and load transients.
