Hello team,
In the formula, we can see three terms being used. Can you please confirm on below"
I_IAC@Vin_min – This is the current flowing in the IAC pin at Vin_min peak which can be calculated as Vin_min(rms) * sqrt(2) /R_IAC where, Vin_min(rms) = 85Vrms or 170Vrms (in our case), R_IAC = resistance connected to the IAC pin
V_VAOUT(min) – Apparently minimum Voltage amplifier output. Is this the voltage amplifier output for Vdc_link(min) which can be calculated as Vdc_link(min) = Vdc_link(nominal) – Vdc_ripple/2 or something else?
V_VFF(min) – The current at IAC pin during Vin(min) peak instant is mirrored with 2:1 ratio into the VFF pin. So, this parameter should be equal to I_VFF*R_VFF = (2*I_IAC)*R_VFF. Is this correct?
Thank you!
Best Regards,
