Part Number: LM5158-Q1 My regulator is working well I was having temperature issues operating at 2Mhz so I decided to switch to 1mhz. Inductor size was doubled and correct frequency set resistor was selected. This improved the overheating a lot. But now…
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…
Part Number: LM5158-Q1 Hello E2E Experts,
Good day.
I am using the LM5158QRTERQ1 in the SEPIC configuration outputting 25V. I've been trying to find a good capacitor to use for my output capacitor that also doesn't take up too much space, but it seems…
Part Number: LM5158-Q1 Other Parts Discussed in Thread: LM5157 I am trying to use this part in the SEPIC topology. In the data sheet it looks like there are two inductors, but when using the quickstart calculator provided in the data sheet I noticed that…
Part Number: LM5158 dear
I want use LM5158 to output +/- 75V/25mA voltage from a input voltage 3.0V~5V. for evaluation the design, I do some simulation and try to evaluate the performance. however, the simulation is always slowly and stop simulation than…
Part Number: LM5158 Other Parts Discussed in Thread: , LM5157 , LM5156 , LM51561 Hi,
I'm looking to design a 15V in, 48V out boost circuit.
I've looked at the following parts:
LM5158LM51581
LM5157
LM51571
LM5156
LM51561
I have a few questions…
Part Number: LM5158 Our customer requires security distance 60V/0.6mm, but our part has ~0.2mm distance from SW to EP as below.
Do we have any possible solution or explanations about this case?
Thank you so much!
Hi David,
I have not seen an update for the last 16 days, so I assume the questions are/or answered and the issue is solved. I close this thread now. If there is still something open reply and the thread will get open again. If you have any other question…
