Part Number: LM3481-Q1 Hello,
We have a SEPIC design including the LM3481-Q1 controller.
According to the datasheet, Cin should be above 100uF.
However, the Powerbench suggests Cin to be tantalum 4.7uF.
The questions are:
1) Who should I follow…
Part Number: LM3481-Q1 Tool/software: Hi,
We made WEBENCH with the specifications that customers want.
