Hi,
Do you know what is the headroom of the internal linear regulator for Vref? If I use it on the 4.5V at the input of VDD, what would the Vref voltage be? I went through the UCC27611 datasheet, the test condition is the datasheet is 12V input. The part can operate between 4-18V. In my application, the input VDD voltage is 5V, but it can also go down to 4.5V.
Thanks,
HSG
