6A, 3MHz, 2.7V to 16V, Step-Down Switching Regulator

The MAX20806 is a fully integrated, highly efficient, step-down DC-DC switching regulator. It is able to operate from 2.7V to 16V input supplies, and the output can be regulated from 0.5V to 5.8V, delivering up to 6A of load current.

The switching frequency of this device can be configured from 500kHz to 3.0MHz and provides the capability of optimizing the design in terms of solution size and performance.

The MAX20806 utilizes fixed-frequency, current-mode control with internal compensation. The MAX20806 features a selectable advanced modulation scheme (AMS) to provide improved dynamic load transient performance. The device also features selectable discontinuous current mode (DCM) operation to improve light load efficiency. Operation settings and configurable features can be selected by connecting pin-strap resistors from the PGM pins to ground.

The MAX20806 has an internal 1.8V LDO output to power the gate drives and internal circuitry (VCC).

The MAX20806 integrates multiple protections including positive and negative overcurrent protection, output overvoltage protection, and overtemperature protection to ensure a robust design.

The MAX20806 is available in a compact 3.0mm x 2.5mm FC2QFN package that supports -40°C to +150°C junction temperature operation.
