Dears,
Please tell us how to calculate LMR36503-Q1 bootstrap resistor Rboot power disspation and its formula.
we need to know it to select Rboot size and power rating.
Thanks.

Hi Maguire,
Please refer to this thread for power dissipation:
To summarize, usually the power dissipation for Rboot is quite small, so an 0402 can be used. Usually, we do not recommend going above 10Ohms. The current standard is to start with 0Ohm and slowly increase, while examining on the bench. Usually for the LMR36503-Q1, a boot resistor is not necessary.
Thanks,
Richard
