Part Number: TIDA-070002 Tool/software: Hi
What's the idea/purpuse of
a) The schottky diode D7. (I know that R8/C43 and Q2 forming a Soft start... but D7?)
b) R14 (Just to have a TP?)
C) the not populated capacitor C47
Best Regards

Hello Daniel,
Hope you are well.
Given that the max output load current from the TIDA-070002 could be 10A, why did you choose a coupled inductor
with a secondary winding…

What is the maximal peak current at the OUT pin? Specified is 200[mA] RMS but Figure 1. goes up to 500 [mA].
I saw several designs (e.g. TIDA-070002…
Hey Paul,
I would look at this for reference: https://www.ti.com/tool/TIDA-070002
You can just bias the voltage on the secondary side to help.
Thanks, Daniel
