Can you please describe the behavior of the TPS61030 under the following two conditions.
Condition 1: TPS61030 Vout =3.8V, VBAT input = 2.7V, output is ENABLED (EN =VBAT)
What would occur if the TPS61030 output is driven by another low impedance source to 4.0V? Would the control loop open the high side FET AND the body diode block Vout from passing to Vin? Would a higher voltage on Vout damage the TPS61030 when it is enabled?
Condition 2: TPS61030 input = 2.7V, output is DISABLED (EN = GND)
What would the TPS61030 do if the output is driven by another low impedance source to 4.0V? Since high side FET is off and body diode disconnected according to datasheet, I believe this should not result in any component damage. I am not sure if there are any other paths through the FB or LBO?
Thank you!
