TPS62130 minimum pulse width

Other Parts Discussed in Thread: TPS62130, TPS62140

Our customer was setting the output voltage of TPS62130 as 1.2V.
In this case, SW frequency is about 800KHz.
Is this correct?
How much is the minimum pulse width of TPS62130?

Regards,

This is listed on page 15 of the D/S.

Here is an app note that explains DCS-Control: http://www.ti.com/lit/an/slyt531/slyt531.pdf

Especially, at lower Vouts, a lower frequency is expected. This increases efficiency.

Yes. You should find the same sentence in that D/S as well.

Is this an issue for you? It is not an issue for the device.
