CONTROL SYSTEM FOR TRANSITIONING A DC-DC VOLTAGE CONVERTER FROM A BUCK OPERATIONAL MODE TO A SAFE OPERATIONAL MODE

摘要

A control system for a DC-DC voltage converter includes a microcontroller having first and second applications. The first application commands the microcontroller to generate a first signal to transition a first plurality of FET switches in the high side integrated circuit to an open operational state and to transition a second plurality of FET switches in the low side integrated circuit to the open operational state. The second application commands the microcontroller to generate a second signal to transition the first plurality of FET switches in the high side integrated circuit to the open operational state and to transition the second plurality of FET switches in the low side integrated circuit to the open operational state.
