Hi,
I'm trying to use WEBENCH® LM2621 to design a SEPIC converter for the LM2621 with the following parameters:
Vin=4V - 12V
Vout=5V
Iout=500mA
However the WEBENCH® LM2621 always says "design can not be created"
I tried to change parameters with lower voltages, current etc, whenever I select inputs that should be implemented by SEPIC converter I'm receiving the same negative answer.
Is there are any bug in the WEBENCH® LM2621, because the data sheet shows me exact that it can be designed. Do you have any Application Note describing step by step how to calculate it?
Thank you in advance
