We have questions about VCC2 capacitor of UCC5390.
In dataseet p.37 11.2.3.2 "Selecting a VCC2 Capacitor",
A 50-V, 10-μF MLCC and a 50-V, 0.22-μF MLCC are selected for the CVCC2 capacitor.
Must we keep the value of voltage and capacitance(50-V, 10-μF MLCC and a 50-V, 0.22-μF MLCC)?
Is this value an example?
Can we change the voltage and capacitance value when we select the VCC2 capacitor?
Our customer have a trouble obtaining ceramic capacitor of 50V-10µF and 50V-0.22µF.
So, our customer thinks that they want to change the value of VCC2 capacitor(voltage and capacitance) according to the secondary condition and spec of MOSFET or IGBT.
Are capacitance and voltage mandatory?
Can we increase or decrease value?
Best regares,
