Notes
Why it is interesting: the classic SiC totem-pole PFC reference, with three interleaved phases and phase shedding. The design guide covers zero-crossing current spikes well. It uses four TIDA-01605 gate-driver boards (cross-linked).
Watch out: TI now points to PMP23338 for current totem-pole hardware and firmware (recorded as successor).
vin is only the stated test point (240 Vac).
