TPS63070: The start up current limit issue of TPS63070

Antony Fu

Part Number: TPS63070

Hello team,

TPS63070 has one start up current limit threshold form the datasheet's test data, but I can not get detailed information about it, so would you like to share more materail about this? and why we need add this limit during start up?

Thanks,

Antony

The converter has been designed with a reduced current limit during start-up to protect the system from any high current consumption during startup . It ensures that the power source does not get empty unwanted or destabilize the other rails connected to the same system

what is the customer's main concern regarding this feature?

HI Sabrina,

Customer is not sure the actual start up current o load, so they are checking with current spec now, many thanks.

Antony
