Part Number: UC2842 Hi,
I have read datasheet of UC2842A and application circuit ( calculation ).
Questions :
1. Snubber Circuit ( RCD snubber selection ) Calculation not specified ? Please give the calculation details.
2. Is there any Simulation Model…
Part Number: UC2842 Just to note to who can be interested, in case no one was aware of it, of a question on a circuit in the datasheet modified in April 2020. The problem is illustrated by Dr Sam Ben-Yaakow in his you tube post: https://www.youtube.com…
Part Number: UC2842 Hi,
I am reading the datesheet of UC2842A. I understood that it is PWM controller. I understood the working of Flyback controller ( attached block diagram http://www.ti.com/lit/an/slva059b/slva059b.pdf or image attached in this thr…
Part Number: UC2842 Hi I have attached two images for more reference.
1.What is the voltage range? ( marked as yellow colour )
2. Explain the Auxiliary Transformer working ? Why it is needed ? ( Marked in red colour )
3. Explain the optoisolator how its…
Part Number: UC2842A Other Parts Discussed in Thread: UC2842 Hello, I've designed a flyback converter with UC2842 IC. Design is based on TI's tool and reference schematics and there is a problem, The AC Board's fuse keeps burning up. When I disable the…
Part Number: UC2842 Other Parts Discussed in Thread: TINA-TI , , UCC28C42 Tool/software: TINA-TI or Spice Models I could not find the flyback transformer type that is used in the current mode switching supply that I wanted to simulate in TINA. All transformers…
Part Number: UC2842 Hi Team,
My customer is evaluating UC2842AN w/ a transformer. All calculated is based on WEBENCH.
Based on WEBENCH result, we create a PCBA to test. However, it doesn't work. Please see attached - PCBA schematic and transformer report…
