MAX77874 Datasheet | Maxim Integrated

EVALUATION KIT AVAILABLE 16A High-Performance Quad-Phase Buck Regulator for Multicore CPU and GPU Processors General Description 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 5m V 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 bines 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.
