LM5155: How to Design a Boost Converter Using LM5155

Part Number: LM5155

Hi,

I think there is a mistake in the Application Report "How to Design a Boost Converter Using LM5155".

Would you please check it?

1.I think the answer should be Cout_min = 34.091uF, not 14.206uF.

2.I think the answer should be Vsupply(off) = 5.5V, not 5.4V.

Best Regards,

Nishie

Hi Yuta,

Thanks for reaching out with your questions and for considering the LM5155 in your design.

It looks like the values calculated values are off but the equations are correct. These will be fixed in the next revision of the application note.

Thanks,

Garrett

Hi Garrett,

Are Cout_min = 34.091uF and Vsupply(off) = 5.5V correct?

Thanks,
