**Part Number:**UCC21542

**Tool/software:**

Hi, I need an isolated gate driver that drives the gate of this IGBT - STGP10H60DF at 60Hz switching frequency. How big should the bootstrap capacitor of UCC21542DWKR be for this case? I think it is very large (>50uF), so is there a workaround for this problem, since I would like to minimize the capacitance of both Cboot and the VDDB decoupling capacitor? Please advise. Thanks!
