12W Flyback needed

Josef Alt

Hi,

My customer is looking for a 12W flyback supply. Vin is 90-270V. Vout is 13V, -13V, 6.5V and Aux 14-16V (depending on transformator). Q100 would be nice. PFC is important, ideally without Optocoupler and low EMI.

Any suggestions?

Thanks

Hi Josef,

Having a 12W output with PFC is not a usual requirement, specifically not with Q100 devices.

Never the less, we have some PFC Flyback designs that might fit here.

Please see the design below as an idea of what it will look like.
