TPS40210 boost question

Other Parts Discussed in Thread: TPS40210

Hi,

I am looking for 5Vin to 60Vout at 100mA boost. Per webench I am looking at TPD40210 but I don't believe this part will do 60V since the DC is 92% which according to Webench I should be able to do. Do you have a tapped inductor boost or flyback design for my application. Also please look into why Webench is recommending this as a possible solution? I would like to get an eval board with the final design.

Thanks for your time. I can be reached at 858-357-4741.

Hi, the SPEC table on datasheet shows the minimum off time of TPS40210 is 200ns.
To get 92% duty circle, the Fsw has to been lower than 400kHz with some margin.

Thanks
Qian

Thanks. SO you recommend this part as long as fsw is less than 400KHz in my application? Where can I get your evaluation board from?
