Part Number: TPS63900

Hi,

Good Day.

I am using this part TPS63900DSKR boost converter.

In my circuit I have I am using 3V0 LDO and this boost converter.

First, I will power up LDO, once Powered by LDO 3V after the 100uf boost converter needs to enable.

Here I will plan to use some RC circuits for 100us delay to enable a boost converter.

Can you please share enable signal Vih and Vil?

In this test condition, Ven applied 3V.

But EN VIH mentioned a 1.2V maximum which is correct.

What is EN signal VIh (Min) voltage?

Best Regards,

Ray Vincent

Hi Ray,

thank you for using the E2E forum.

Not sure if I understood the question right, as in my opinion the answer is just in the line below in the screenshot of the datasheet you have sent:

VIL min = 0.4V

Best regards,

Stefan

Hi Stefan,

Good Day. On the datasheet, there is no minimum voltage for VIH and that's why the customer is asking for it. Thanks.

Best Regards,

Hi Ray,

as this is a digital IO only the upper limit when going high and the lower limit when going low are specified.

Best regards,

Stefan
