Hello, all

Now we are considering to use TPS62510.

Then would like to ask you regarding the detail of EN pin on this device.

We could not find the information from this datasheet whether the output is high impedance when EN pin is low.

Please let us clarify on this matter.

We thank you in advance for your information.

Best regards,

Per the D/S, the device is disabled when the EN pin is low. So, it is off. Both switching FETs are open.

You might also look at the newer TPS62080, TPS62060, or TPS62090.

Hello, thank you for your reply.

I suppose that the SW pin will be Hi-Z when the device is disabled.

Please let me clarify once again whether my understanding is correct.

Thank you in advance for your information.

Yes, the SW pin is high-Z.
