Circuit description
Doc ID 15209 Rev 3
15/28
tRCRISE = 600 COFF
capacity. It has to be said that t
ON is always bigger than t
ON(MIN) because the device imposes
this condition, but it can be smaller than tRCRISE - tDT. In this last case the device continues
to work but the off time tOFF is not more constant.
So, small COFF value gives more flexibility for the applications (allows smaller on time and,
therefore, higher switching frequency), but, the smaller is the value for COFF, the more
influential will be the noises on the circuit performance.
