TPS2553D: Use power switch to charge super capacitor

Part Number: TPS2553D
Other Parts Discussed in Thread: TPS2553

Hi Team,

My customer now would like to use TPS2553D to charge super capacitor. 

when the charge current is lower than 400mA, TPS2553 is on, then current could flow into capacitor to charge it.

when the charge current is higher than 400mA, TPS2553 is off, then current stop flowing  into capacitor.

It means that TPS2553D need to on and off many times, and whether it will have risk if on and off because of current limit for many time?

Whether power switch could use in super capacitor charger?

    Hi Amelie,

    I am not sure whether it can be used in super cap charger.

    But, for on and off many times due to current limit, that's fine.

    For TI's policy, I will first click resolved button.

    If you have any other concern, contact me any time.

    If you think resolved, please help click 'Issue is solved button'.

    Thanks.
