UCC28070APWR SCH_RD-Markup.pdf

Hi Kygo, please see the mark-up file of the schematic you provided.

In the future, please have the customer fill out the calculator tool and include that with the schematic (www.ti.com/.../sluc114). This prevents a lot of guesswork on our side and also saves a lot of time. It also ensures that the intentions of the customer design are clear since it's impossible to verify certain component values unless the customer enters their intended design parameters. This makes for a more robust review. Please also note that the boost inductor values were not included in the schematic so I had to make assumptions about them and the associated parameters like peak currents.

Hi Kygo,

Sorry for the inconvenience, but I wanted to update the schematic review markup. I removed two comments, so nothing major from the earlier markup.
