MOSFET failure protection for a single output polyPhase converter

MOSFET failure protection for a single output polyPhase converter

Technology News |
The low output voltage rails in many of today's leading edge communication, networking, computer and industrial systems must be designed to meet the competing demands of higher load current, higher efficiency and diminishing amounts of board real estate. For cases where the load current is high, the most effective approach is to tie two or more phases together.

This poses a design challenge for high-end systems which require 100% uptime or which use high cost processors: how to protect the load and to ensure the output continues to regulate if a DrMOS or MOSFET failure occurs. In this video, we will show how the LTC3774 controller can be used in conjunction with Hot SwapT circuits and ideal diode circuits to meet this challenge.
