Datasheets for MP2690 and MP2632 does not show the state of Vsys during removal of USB In or Adapter to Vin.
Some other IC’s we tried from other companies had 10-40ms power loss at Vsys during removal of Vin. This interferes with the operation of our product. How soon can boost take over after Vin is lost?
Can you please clarify what happens during this event?
