This reference design consists
of four main sections that intercommunicate:
- A power board comprising the power
stage SiC MOSFETs, a high frequency transformer, current sensing electronics,
and the system power tree
- A TMDSCNCD280049C control card to
support digital control
- Four gate driver cards, each having
a UCC21530 to drive the four legs of the DC/DC converter
- Two isolated high-voltage (ISOHV) sensing cards, each having an AMC1311 device
to sense the input/output bus voltage
Note: The isolated high-voltage (ISOHV) sensing card is
a reuse of the design from TIDA-01606 Rev. E4 ISOHV card.
