Part Number: TPS61022
I am designing a circuit that has two power sources that go through regulators with outputs that will be tied together.
Regulator A: Boost (3-5 Vin to 5.2 Vout) using the TPS61022.
Regulator B: Buck (9-15 Vin to 5.2 Vout)
When using Reg B, efficiency is not important. It is critical though when using Reg A. My question involves the behavior of the TPS61022 when turned off. When Reg B is in use, the TPS61022 will have 0V at VIN and EN but 5.2V at Vout. Will the TPS61022 draw reverse current or be damaged in this state? I don't want to include load switch at output due to added losses and cost.
Thanks,
Josh
