Alternate 12V supply for RDR239 and DER394

Posted by: rffx on Wed, 06/02/2021

 Hi

I am trying to reduce the component cost of the 12V supply that is used for a PFC 24V AC-DC converter.

Currently my design uses the LinkSwitch circuit similar to RDR-506 (TN2 LNK3204D/P/G) as an auxilary 12V supply for the PFC.

What less expensive alternatives do you suggest?

Thank you

Hi rffx,

Good day!

If you wouldn't mind, may I ask for the application and the standby power of your design?

Thanks.
