Part Number: LM5017

Hello Mr. Xiang Fang and Wei Liu,

Kindly confirm the LM5017 VCC bypass voltage. Conflict arises from LM5017 datasheet & your application note on LM5017

The "section 7.3.2 VCC Regulator" in LM5017-datasheet viz. TI document SNVS783J; suggests VCC bypass voltage as 8.55-13V

Whereas "Step 1 - Determine the primary-side output" in your app-note, quoted below, suggests VCC bypass voltage as 7.8V
