MAX77812 PCB Layout Guide

Abstract: The MAX77812 is a quad-phase, high-current buck converter for high-end gaming consoles, VR/AR headsets, DSLR cameras, drones, network switches and routers, and FPGA systems that use multicore processors. The multiphase buck architecture reduces the size of the external components while providing the ripple current cancellation and world-class transient response. Differential remote sensing feedback enables tight DC and AC accuracy at the point of load. The MAX77812’s flexible architecture allows five user-selectable phase configurations: 4, (3+1), (2+2), (2+1+1), and (1+1+1+1).
