The MAX20830/MAX20830T are fully integrated, highly efficient, step-down DC-DC switching regulators with a PMBus interface. The devices operate from 2.7V to 16V input supplies, and the output can be adjusted from 0.4V to 5.8V, delivering up to 30A of load current.
The switching frequency of these devices can be configured from 500kHz to 2MHz to provide the capability of optimizing the design in terms of size and performance.
The MAX20830/MAX20830T utilize fixed frequency, current-mode control with internal compensation. The ICs feature a selectable advanced modulation scheme (AMS) to provide improved performance during fast load transients. Operation settings and configurable features can be selected by connecting pin-strap resistors from the PGM_ pins to ground or using PMBus commands.
The MAX20830/MAX20830T have an internal 1.8V LDO output to power the gate drives (VCC) and internal circuitry (AVDD). The devices also have an optional LDO input pin (LDOIN), allowing connection from a 2.5V to 5.5V bias input supply for optimized efficiency
The IC has multiple protections including positive and negative overcurrent protection, output overvoltage protection, and overtemperature protection to ensure robust design.
The devices are available in a 4.3mm x 6.55mm FC2QFN package that supports -40°C to +125°C junction temperature operation. The MAX20830/MAX20830T’s package footprint is compatible with the MAX20840T, MAX20815, and MAX20810.
