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 LM5017The "section 7.3.2 VCC Regulator" in LM5017-datasheet viz. TI document SNVS783J; suggests VCC bypass voltage as 8.55-13VWhereas "Step 1 - Determine the primary-side output" in your app-note, quoted below, suggests VCC bypass voltage as 7.8Vwww.edn.com/.../Product-How-to--Fly-Buck-adds-well-regulated-isolated-outputs-to-a-buck-without-optocouplers-
The electrical characteristics table of the datasheet gives the true value - 6.25V min, 7.6V typ, 8.55V max.
Section 7.3.2 refers to driving a voltage on VCC externally.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
