16A High-Performance Quad-Phase Buck Regulator

for Multicore CPU and GPU Processors

MAX77874

General Description

Applications

● Smartphones, Tablets, Ultrabooks

● DSLR, Mirrorless, Action Cameras

● Gaming, Drones, Robots, Virtual Reality

The MAX77874 is a quad-phase, high-current, step-down

buck regulator for CPU and GPU multicore proces-

sors. Proprietary IP provides industry-leading transient

response, output voltage accuracy, high efficiency, and

miniature PCB footprint.

● AI, Machine Vision, Embedded Microprocessors

Beneﬁts and Features

● Operating Range

The output voltage is I C 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

• V : 2.7V to 4.8V

• V

: 0.25V to 1.30V in 5mV Steps

OUT

• I

: Up to 16A

OUT

● Fast Load-Transient Response

• 25mV Droop in FPWM and Turbo-Skip Modes

• 40mV Droop in Skip Mode

rates are I C programmable and controlled through dedi-

cated logic inputs.

• Conditions: 3.7V , 0.9V

, 200mA to 9.2A

OUT

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.

● Tight V

Accuracy

OUT

• 0.28% (max) Initial Accuracy at 0.9V

• 1.5% (max) Over Line/Temperature

OUT

• 3mV

(typ) Ripple at All Loads
