Part Number: UCC28810EVM-002
Hi all,
I need some clarifications on the schematic of the UCC28810EVM-002.
My customer is using the board as a reference but wants to use 2x UCC28810 (1x for PFC, 1x for _Buck).
the customer has asked some questions regarding the schematic of the EVM that I cannot answer:
-
Why the bias circuitry of the PFC showed in the calculator (based on BJT) is different from the one showed in the schematic (user guide)?
-
Benefit of boost follower configuration if any.
-
The VOSENS_BK net label does not refer to anything in the schematic (buck stage)
-
Why is VINS monitoring the VDD_BK ?
-
Is there a way to configure (through any formula) the value of Current sense and feedforward resistors in the buck stage ?
regards,
Domenyco
