Mixed-signal IC solutions leverage on superior isolation and high voltage expertise to enhance power system performance, flexibility and reliability while reducing system size and cost.
The clock is on the low voltage side and does not need to be isolated. The FET gate control signals are isolated from high voltage side using the Si8234 on the POL board. The Si8234 has built in isolation as well as gate drive capability.
