Hi,
We are considering using the TLV62568/TLV62568A in a design where the input is 3.1 - 3.5V and the output is 3.3V. It is acceptable to pass-through the input when it is below 3.3V+ dropout.
When I try to do webench design using 3.5V as input (both min and max = 3.5V) and 3.3V as output, it does produce a design for the TLV62568A, but not for the TLV62568, for which I get the message that a design could not be created.
As far as I can see from the datasheets the TLV62568 and TLV62568A are identical, except the latter is forced PWM whereas the former has a power save mode for low load, so it seems it should be possible to use either.
Is there a reason why the Webench does not provide a design from the TLV62568? Are there are other issues to consider?
Thanks,
Best regards,
Anand.
