MAX15109 datasheet



The MAX15109 high-efficiency, current-mode, synchronous step-down switching regulator with integrated power switches deliver up to 8A of output current. This regulator operates from 2.7V to 5.5V and provides four output voltages using two VID control inputs.
This IC utilizes a current-mode control architecture with a high gain transconductance error amplifier. The current-mode control architecture facilitates easy compensation design and ensures cycle-by-cycle current limit with fast response to line and load transients.
