TPS60301 - About behavior when VOUT becomes higher than VIN and EN pin is LOW

I tested this configuration and it seems ok.

With EN = GND and no Vin connected, there was no leakage and no reverse voltage.

With 1Vin, there was about 20uA of reverse current which pulled up Vout1 to about 200 mV.

Vout2 was applied above the setpoint.

Hi Chris-san,

 

Thank you for your kind support and detail information.

I understood your evaluation contents as follows.

Is my understanding correct?

 

And, I have one more question.

The following contents are listed in a datasheet.

So, may I apply VOUT2=3.0V when EN=GND?

Yes, you can apply 3V to the output.

The 20 uA flowed into OUT2. Some of it likely went into the voltage divider on OUT2 as well as other internal circuits.

Hi Chris-san,

Thank you for your prompt reply.

I understand. Thank you very much.

Hi Chris-san,

 

I have one more question.

Does this reverse current(20uA) flow into VIN pin?
