My customer wants to drop-in replace IFX's isolated gate driver with UCC5350.
There is a problem that for recent design, the VCC1 capacitor is 1uF, while VCC2 capacitors are 1uF+1uF+0.1uF. But in our datasheet, we recommend 10uF+0.22uF for Vcc2.
We want to know that whether there is any risk to maintain the present design, as for their board, the bias power supply output is located near the Vcc2 pin. Or is there any other test results you can provide with lower capacitance than recommended? Thanks.
