TPS61089: Question about the soft start application

Part Number: TPS61089

Hi team,

     My customer use TPS61089 device to convert 3.6V input to 11V output as below. And then disable the device, the body diode would be reverse blocking because output voltage is higher than input voltage. And after about a few hundred milliseconds, the output voltage would only drop to 10V because of the large capacitor and the device would be enabled again at this time. Is it ok for this application? This will happen periodically, is there any notice or error? Thanks a lot!
