Analog Devices Inc. MAX20830 Integrated Step-Down Switching Regulators
Analog Devices Inc. MAX20830 Integrated Step-Down Switching Regulators are fully integrated, highly efficient, step-down DC-DC switching regulators with a PMBus interface. The devices support a -40°C to +125°C junction temperature range and 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 can be configured from 500kHz to 2MHz to provide design optimization capability in terms of size and performance.
MAX20830 utilizes fixed-frequency current-mode control with internal compensation. The ICs feature a selectable advanced modulation scheme (AMS) to improve performance during fast load transients. Operation settings and configurable features can be selected by connecting pin-strap resistors from the PGM_ pins to the ground or using PMBus commands. An internal 1.8V LDO output powers 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.
Protections include positive and negative overcurrent protection, output overvoltage protection, and overtemperature protection to ensure a robust design. The Analog Devices MAX20830 are available in 4.3mm x 6.55mm FC2QFN packages that are footprint compatible with the MAX20840T, MAX20810, and MAX20815.
