General Description
The MAX20828T is a dual-output, fully integrated, highly efficient, step-down DC-DC switching regulator. The regulator is 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 8A of load current per output. The two outputs can be connected in parallel as a single-output, dual-phase regulator that supports up to 16A 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 MAX20828T utilizes fixed-frequency, current-mode control with internal compensation. The dual-switching regulators operate 180° out-of-phase. The MAX20828T 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 the ground.
The MAX20828T 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 MAX20828T integrates multiple protections including positive and negative overcurrent protection, output overvoltage protection, and overtemperature protection to ensure a robust design.
The MAX20828T is available in a compact 3.5mm x 4.6mm FC2QFN package that supports -40°C to +125°C junction temperature operation. MAX20828T is footprint compatible with MAX20808/MAX20808T and MAX20812/MAX20812T.
