Need non isolated 17W at 24V. Which chip?

Posted by: treez on 05/07/2023

Hi,

We wonder whether its Tapped buck or non isol flyback etc etc?

We thought of tapped buck with LNK3209 but its fsw is only 66khz.

So we think of innoswitch...but it seems odd..because we dont need the isolation.

Just wondering abotu a non isolated topswitch flyback design too?

Hi Treez,

What is the input voltage?

LinkSwitch-CV can supply your required output power if the input is 230VAC (see datasheet: linkswitch-cv-data-sheet.pdf (power.com) )

Both ICs are using PSR.

Thank you.

Thanks, vac input is 100-265vac
