I would like to use the TLV2186 to modify the feedback of a DC-DC converter, and I want to power the TLV2186 from the output of the DC-DC converter. During normal operation the output of the DC-DC converter ranges from 6 V to 10.5 V, which is well within the recommended supply voltage range for the TLV2186. What I would like to know, however, is the state of the op amp output during start-up, when the output of the DC-DC converter ramps up from 0 V to 4.5 V. Does the op amp output stay low? Does it stay high? Is it completely undefined? Does the TLV2186 include any kind of internal UVLO function (I'm thinking that it might, to ensure correct start up of the chopping circuitry).
Thanks,
Nigel
