TPS22970: TPS22970

Part Number: TPS22970

I'd like to use TPS22970 to reduce in-rush current.

Since it is placed on very first input of the power supply, it should be enabled automatically when the power supply is on.

So, ON pin needs to be tied to Vin through a pull-up resistor like below picture.

Please confirm if this is ok. What resistance of the pull up resistor do recommend?

Hey Youngmin,

I do not see a necessity of a pull-up resistor. You can connect the Vin pin directly to the ON pin. However, do you have any other reasons/motivations behind using a pull-up resistor?

Thanks,

Dhanya

The pull up resistor is just for a debugging purpose. Thank you very much.
