Part Number: UCC14140-Q1
Other Parts Discussed in Thread: UCC14141EVM-068, UCC34141
I am looking to use the UCC14140-Q1 chip to supply approximately +12/-4V to a gate driver driving SiCFETs. The FETs form a high-voltage isolation circuit that feeds a noise-sensitive amplifier that requires high-voltage protection. I have been looking at the UCC14141EVM-068 and the output voltage rails seem to be quite noisy. Would you have any suggestions for a "smoother" output that can be used by the gate driver? My initial thought was to use LDOs to further regulate the output. The current rating doesn't need to be above 100mA for either rail.
