Circuit Analysis




The X470 Taichi Ultimate shows us the goods with the heat sinks removed!





We see the VRM here is in a 12+4 phase mode and uses the IR35201 in 6+2 phase mode. The digital PWM from International Rectifier is used to its maximum, and each power stage consists of a 60A inductor as well as a Texas Instruments CSD87350 NexFET rated for 25A each. These NexFETs are some of the finest dual N-channel MOSFETs, and while we typically see dual N-channels from Fairchild, Sinopower, or even ON Semi it's nice to see the Texas Instruments variant here.




Those 6+2 phases from the PWM controller are doubled to 12+4 by eight IR3598 phase doubler plus integrated driver chips meant for this very purpose. The memory PWM is the UPI uP1674P, and the dual phases utilize the Texas Instruments 25A NexFETs.
