LM5022: Boost converter: Vin = 60-75 VDC, Vout = 110 VDC, Iout = 6 A max.

Jeet Parsana

Part Number: LM5022

I want to design a DC-DC boost converter with the following specifications.

Vin = 60-75 VDC, Vout = 110 VDC, Iout = 6 A (max)

So far, I am not able to find any boost ic which meets above specifications. So, I was thinking of using two LM5022 boost controller with 30-36 VDC input (i might be able to do that, as i am using two solar panels in series) and 55-60 VDC output and connecting the output in series.

My question is, will this work?

Hi Jeet
Are two solar panels' output isolated or not? If the solar panel's output is not isolated, you can't to connect LM5022 output in series.
thanks

Hello Jing,

Thank you for the quick response. If I isolate solar panel's output, is it then possible to connect two LM5022 output in series?

If you isolate the panel and each has one LM5022 boost stage, then you can stack up the outputs in series.
