Tool/software:

Dear Sir,

I am currently designing a DC-DC converter using the PSFB configuration, with an input voltage range of 16.8V to 90V and an output of 48V at 30A. I require both constant current (CC) and constant voltage (CV) monitoring, utilizing the UCC28951-Q1 IC.

I understand that I need to short the EA- (pin 3) and COMP (pin 4) pins, and connect a comparator to the EA+ (pin 2) pin. However, I would appreciate your guidance on the calculation of the resistor divider for this setup.
