TPS43060: TPS43060 Vcc Resistor

Hi Tateo,

R19 can be removed.

Thanks

Thank you for your reply.
If R19 is removed, is there any conserns? I think R19 and C6 create R-C filter. Why does it be needed?

Best Regards,

Hi Tateo,

One possible reason is R19 is used to slow down the turn-on of low-side FET to reduce the voltage spike on switching node, because during low-side FET turn-on, the gate current is drawn from Vcc bypass cap (C6).

To play safe, I think you can keep the placeholder for R19 and set its value to 0ohm in your design.

Thanks
