LMR16020: dv/dt limitation when power up

Rebecca Li

Part Number: LMR16020

Hi Team,

Are there limitations of max or min dv/dt when LMR16020 is powered up?

Thanks.

HI Rebecca

I would say there is no limit for normal usage. What dv/dt value would customer apply?

Best regards.

Hi Gui,

Customer is afraid of the fault conduction of the internal MOSFET due to large dv/dt. The max value from system will be 1~2V/us.

Are there any comments on the influences or suggestions?

Thanks.

HI Rebecca

Fault conduction will not happen under such Vin application, thanks.

Thanks.
