Hi Vitalij,

Thanks for reaching out.

For such power levels, maybe a digital solution is the way to go.

Thank you. But maybe you have a two-phase step-up dc-dc CCM like ucc28070???

Hi Vitalij,

An asynchronous solution could be using TPS40210 in a 2phase setup. This would require a NE555 in addition.

But ucc28070 seems also like a good fit.

Best regards
