Part Number: LM5157-Q1 Other Parts Discussed in Thread: LM5157 Tool/software: Hi,
I am doing the AC Sweep simulation for LM5157 Sepic converter by using the Average model suggested by TI.
I have connected the AC source in series with the FB line and…

Hi,
Iam Doing the Sepic Converter Simulation using the LM5157 IC Model, Transient analysis is taking normally 20 to 30 minutes for 3mS duration simulation. But, when i am…
Hi Niklas,
Thank you for your support for resolving the coupled inductor modeling issue.
Previously i did the DC Sweep with LM5157 and observed it taking too much time to simulate, almost 2 days i waited for completing the DC Sweep simulation, finally…
Part Number: LM5157-Q1 Other Parts Discussed in Thread: LM5157 Tool/software: Hi,
I am doing simulation in TI PSpice tool, created a SEPIC converter simulation using LM5157 model, i have used the Diode from TI modeling application, Simulation was working…

Hey Everyone
I am currently facing an issue with high power LED-driver circuit:
The Output is connected to a Led string with a total forward voltage of around 26V and the current in this case is 1.5 A Looking at th…
Part Number: LM5157 Tool/software: Hi,
On a non-flyback topo, what is the VOUT value if chip is disabled (UVLO = LOW)? Assuming no Vdiode loss. Some boost converters completely ignore Vin and just pass through it to Vout, but some open the gate on SW…
Part Number: LM5157 Other Parts Discussed in Thread: LM5158 , I am making a universal design that ideally can use LM5157 or LM5158
Assuming that the requirements do not exceed the capabilities of the LM5158, could I connect PIN 12 which is supposed NC on…
Part Number: LM5157 Hello,I've recently designed a two-layer demo board of the LM5157QRTERQ1. I have attached a potentiometer to its feedback network in order to change the output voltage. At a 15W output (I am currently testing with 20V output and 26…
Part Number: LM5157 Hi Team,
My requirement is that the input voltage is 16V and needs to be converted into an output voltage of 30V/6A. Have any suggestions?
