Part Number: LM5157EVM-FLY Other Parts Discussed in Thread: LM5155 Hello E2E,
I'd like to modify the LM5157EV-FLY from string voltage FB to coupler FB. I checked the User's guide, that the FB circuit with coupler has not connect to Vout. To change…

Hi team,
Could you please tell me how to determined the output current? for EVM, could I change the output current? if I can, how to set. the output current only can support to 75mA. I am curious why the EVM set this current…
Part Number: LM5157EVM-FLY Hi Experts,
Regarding to the LM5157EVM-FLY, the three isolated outputs are in different current.
1. May I know how to set these output current?
2. From my perspective, three phases mean the three output will be the same.
Am…
Part Number: LM5157-Q1 Other Parts Discussed in Thread: LM5157EVM-FLY I am trying to design a flyback converter using LM5157-Q1
Is there an EMI performance report of this IC used as a flyback?
My specs are:
Input: 8 to 18V
Output:+15,-8,+15,-8,+15,-8V…
Hello,
The customer can use the LM5157 in flyback configuration, there is a flyback EVM with 4 outputs available on the product folder ( https://www.ti.com/tool/LM5157EVM-FLY ), the schematic is at page 13 of the user's guide ( https://www.ti.com/lit…
Hi Arvind,
based on your schematic your output voltages are isolated from the input voltage.
So the polarity on the input is more or less a don't care - you just swap the supply input the the converter sees again a positive input and the same on the output…
