Part Number: LM3481 Other Parts Discussed in Thread: LM5158 , LM5157 Hello, Page 22 of the datasheet, states that the power of the converter can be used in parallel as it will share the current automatically. How can we achieve this performance using EVM…
Part Number: LM3481-FLYBACKEVM Other Parts Discussed in Thread: LM3481 Hello team,
My customer is using LM3481 by referring LM3481-FLYBACKEVM( https://www.ti.com/lit/ug/snvu528/snvu528.pdf ).
Can you please let me know how C16(0.22uF) was determined?

Part Number: LM3478 Other Parts Discussed in Thread: LM3481-FLYBACKEVM , LM3481 , LM5155 , LM5156 Hello, My customer wants to evaluate LM3478 for flyback topology. But we don't have any flyback EVM with LM3478. Then they think using LM3481-FLYBACKEVM would…
Hi Vanja,
Thanks for sharing the simulation. So the ISEN signal is fine and does not trigger OCP. I am more concerned about the COMP pin signals, which seems to stay low and causes the small duty cycle. This may be related to the optocoupler model used…
Part Number: LM3481-FLYBACKEVM Hi Elisabetta,
Thanks for your comments in previous forum: https://e2e.ti.com/support/power-management/f/power-management-forum/980649/lm3481-flybackevm-question-on-feedback-net/3623182#3623182
One more question may need…
Part Number: LM3481-FLYBACKEVM Other Parts Discussed in Thread: LM3481 Hi Team,
Could you help to comments why we add D4 D5 on feedback net of LM3481?
Thanks.
Regards, Sunny
Part Number: LM3481-FLYBACKEVM Other Parts Discussed in Thread: LM3481 Hi Team,
Could you let me know if we use Flyback topology of LM3481.Do we have OVP function?
If we have, what is the operation principle? I see the sec7.3.1 but it look like OVP will…
Part Number: LM3481-FLYBACKEVM Other Parts Discussed in Thread: LM3481 , TL431 Hi Team,
LM3481 have output OVP function.
Could you let me know how to measure the feature for OVP using flybackEVM?
I attempt to short the LTV-817S pin1/2, output voltage clamp…
Part Number: LM3481-FLYBACKEVM Other Parts Discussed in Thread: LM3481 Hi Team,
I have a LM3481-FLYBACKEVM at hand. I would like to change the output voltage from 12V to 5V. Could I modify the FB resistor directly to achieve my purpose>?
Regards, …
Part Number: LM3481-FLYBACKEVM Hi Team,
We use the EVM to do measurement and we find that temp is too high on MOSFET and diode.
Could we use parallel MOSFET and diode for current sharing? (D1 and Q1 in schematic) http://www.ti.com/lit/ug/snvu528/snvu528…
