How Overcurrent Protection Works in the 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 multi-core processors. This application note explains the MAX77812 overcurrent protection scheme and provides IPLIM/IVLIM selection guidelines for a given maximum load current.
