Part Number: TPSI3050

Tool/software:

We are planning to use TPSI305x-Q1 (Driver) and SIR5802DP-T1-RE3 (MOSFET) for our design and Also,we are going with two wire mode design and below attached schematic snap.kindly check this selected capacitor  value on this schematic.

MOSFET Qg = 60nC

    Hello Prema Preumal,

    Thanks for reaching out to our team on E2E. All of the capacitor values have been chosen correctly in your design. Currently VDRV will drop by 0.73V when switching with the current values. This can be mitigated by increasing the CDIVx capacitors to 470nF. 

    I would also like to inform you that the current configuration has a maximum switching frequency of 630Hz.

    Regards,
