Hi,
i'm designing a boost-boost in order to obtain a negative 24 voltage from 12Volt input.
i'd like to avoid that with a bad mos pilot of the first stage boost or with a fault that put the first mos always opened, the second stage could generate a -12V negative voltage from a 12V out of the first stage.
Is it possible? What kind of measures could i take to put my converter in safe state in case of fault?
Thanks.
p.s in safe state i mean a 0 voltage out of the second stage.
