TPS563219: TPS563219 power on inrush current response time

Part Number: TPS563219


Dear Sirs:

what's the TPS563219 power on inrush current protection response time and blanking time. I search no from the datasheet.

The TPS563219 output capacitor load ability is very low. We find the output capacitor higher to 100uF, the part couldn't power on sometimes.

we add the softstart time the infush can get down but the softstart time is too long also.

Does TI has the TPS56XX series capacitor load test data and design details for the power on sequence comparator and time delay function?

By the way, the part power limit parameter "Not production tested."  does it one design parameter only?

 

  • Hi,

    When output is overload and undervoltage, IC will enter hiccup mode. you can find the hiccup power on time is 1ms and off time 7ms.

    The output capacitor is not recommended higher than 68uF. Long softstart time is necessary with large Cout.

    "Not production tested." does not one design parameter only, we did plenty of designs and tests.
