How to Program Startup and Shutdown Sequence with MAX77812

Abstract: The MAX77812 is a quad-phase, high-current, step-down (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 MAX77812 has factory-programmable OTP (one-time programmable) options for customizing the startup sequence and separate register sets for the shutdown sequence. This document explains how to program those registers and provides an example.
