Product Details

The MAX77874 is a quad-phase, high-current, step-down buck regulator for CPU and GPU multicore processors. Proprietary IP provides industry-leading transient response, output voltage accuracy, high efficiency, and miniature PCB footprint.

The output voltage is I²C programmable from 0.25V to 1.30V in 5mV steps. Output current capability is 16A. Rotational phase spreading ensures high efficiency and low ripple at light loads with seamless operation across all varying loads. Turbo skip mode combines the same transient response of forced-PWM mode with light load efficiency similar to Skip mode. Soft-start and DVS ramp rates are I²C programmable and controlled through dedicated logic inputs.

The MAX77874 is offered in a 48-bump, 0.35mm pitch WLP array and is specified over the -40°C to +85°C temperature range.
