The MAX16731 is a fully integrated, highly efficient, step-down DC-DC switching regulator. The regulator is able to operate from 2.7V to 16V input supplies, and the output can be adjusted from 0.5V to 5.8V, delivering up to 30A of load current.

The switching frequency of the device can be configured from 500kHz to 1.5MHz and can optimize the design in terms of size and performance.

The MAX16731 utilizes fixed frequency, current-mode control with internal compensation. The IC features advanced modulation scheme (AMS) and selectable discontinuous current mode (DCM) operation to provide improved performance. Operation settings and configurable features can be selected by three programming pins PGM0, PGM1, and PGM2.

The MAX16731 has an internal 1.8V linear regulator (LDO) output to power the gate drives (VCC) and internal circuitry (AVDD).

The IC has multiple protections, including positive and negative overcurrent protection, output overvoltage protection, and overtemperature protection to ensure robust design.

The device is available in a compact 2.52mm x 4.89mm WLP package. It supports -40°C to +125°C junction temperature operation.
