The MAX15053, Maxim’s new current-mode, synchronous step-down switching regulator with integrated power switches, delivers up to 2 A of output current. The device operates from 2,7 V to 5,5 V and provides an output voltage from 0,6 V up to 94% of the input voltage, making the device suitable for distributed power systems, portable devices and pre-regulation applications.
The MAX15053 utilises 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. The device offers selectable skip-mode functionality to reduce current consumption and achieve higher efficiency at light output load. Its low RDS(ON) integrated switches ensure high efficiency at heavy loads while minimising critical inductances, making the layout design a much simpler task with respect to discrete solutions.
