Part Number: LM5157EVM-SEPIC Other Parts Discussed in Thread: LM5158 Tool/software: I am using the LM5157EVM SEPIC converter. I am using LM5158 IC in the EVAL board. I am using a 24 V output and around 120 mA load. I have changed the feedback resistor…
Part Number: LM5157EVM-SEPIC Other Parts Discussed in Thread: LM5158 , LM5155 Hello,
I was hoping to get some assistance for the LM5157EVM-SEPIC. Currently, I have it set such that it operates within a 10-20V threshold by manipulating the threshold resistor…
Part Number: LM5157EVM-SEPIC Other Parts Discussed in Thread: LM5158 , LM51581 I have a modified LM5157EVM SEPIC with an LM51581 where the Bias if fed by the input and output through diodes (J6 1-2, J7 1-2). I would like a turn on at 6V, and a turn on at…
Part Number: LM5157EVM-SEPIC Other Parts Discussed in Thread: LM5158 I was trying to use the LM5157EVM-SEPIC board to test the LM5158QRTERQ1 part. I am trying to test with an input range of 17V-60V and output 25V, so I made some modifications to the board…
Part Number: LM5157EVM-SEPIC Other Parts Discussed in Thread: LM5157 I am evaluating the LM5157 SEPIC. I would like to run the circuit below the 4V, so I am trying to move the bias pin from the input to the load. I am doing this by removing the J7 pin…
Part Number: LM5157EVM-SEPIC Hi, I have a question for input voltage range of LM5157EVM-SEPIC.
It looks that the spec of input voltage range in electrical performance table requires 6V to 32V of input voltage for 1A load and 4V to 6V for 0.5A to 1A load…
Hi Rayees,
Thanks for splitting the requests into separate threads. This will maintain a much better overview on each topic!
Unfortunately, the average simulation model is designed for a Boost topology only. There is no average testbench available for…
Part Number: LM5158-Q1 Other Parts Discussed in Thread: LM5157EVM-SEPIC , LM5158 , LM5157 Hello, we are trying to use the LM5158-Q1 in the SEPIC topology to output 25V with a max of 1A. We built a prototype and tested with a half amp load and saw a very…
