The MAX20812/MAX20812T is a dual-output, fully integrated, highly efficient, step-down DC-DC switching regulator. These regulators are able to operate from 2.7V to 16V input supplies, and each output can be regulated from 0.5V to 5.8V, delivering up to 6A of load current per output. With the MAX20812, the two outputs can be connected in parallel as a single-output, dual-phase regulator that supports up to 12A 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 MAX20812/MAX20812T utilizes fixed-frequency, current-mode control with internal compensation. The dual-switching regulators operate 180° out-of-phase. The MAX20812 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 MAX20812/MAX20812T has an internal 1.8V LDO output to power the gate drives (VCC) and internal circuitry (AVDD). The device also has an optional LDO input pin (LDOIN), allowing connection from a 2.5V to 5.5V bias input supply for optimized efficiency.

The MAX20812/MAX20812T integrates multiple protections including positive and negative overcurrent protection, output overvoltage protection, and overtemperature protection to ensure a robust design.

The MAX20812/MAX20812T is available in a compact 3.5mm x 4.6mm FC2QFN package that supports -40°C to +125°C junction temperature operation. The MAX20812 package has an open top, and the MAX20812T package has a closed top.
