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
Rolf
Part Number: UC1845A-SP Other Parts Discussed in Thread: TIDA-070002 Tool/software: Dear Support
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) where…
Part Number: TIDA-070002 Other Parts Discussed in Thread: UC1901 , , UC1843A Hi,
I'm interested in UC1901, I saw TIDA-070002. Thank for this design note!
Q1) For the primary side of magnetic feedback, there is offset network with R20 and R29. What is…

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 rated…
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

Hello,
I have some questions about the TIDA-070002 reference design:
1. why isolate the feedback loop, what advantage does this give?
2. would…
Hey Karthik,
You are able to do feedback without optocoupler with UC1901-SP.
There is an example here:

My immediate need is to come up with an architecture for a HARD Isolated House-Keeping power supply (~50W).
Similar to TIDA-070002

Part Number: UC1843A-SP Other Parts Discussed in Thread: UC1843-SP , TIDA-070002 , UC1843 , UC1901-SP Hi,
I have a customer interested in the UC1843-SP.
Please help answer the following question.
I saw the sample circuit in the datasheet and the TIDA-070002…
Hey Vikrant,
The IC you choose should work for the topology.
I do notice in the schematic that you use LM431 which has a reference voltage of 2.5, thus you would be unable to make a 2 V output.
I mostly deal with custom transformers for designs and if…
