TPS54140: Use consultation

Anna

Part Number: TPS54140

Hi Dear,

Can the TPS54140 limit output current through COMP and how to set it

Hello

It is not a good idea to use the COMP pin to limit the output current of the device.

The voltage on the COMP pin is only loosely related to the maximum output current.

Thanks

Hi Frank,

Is there any other way to limit the output current

Hello

You would need to devise an external current sense using an opamp that connects to the FB input.

Thanks
