LT8315. 2 isolated outputs ?


I am using the LT8315 with the transformer 750316022 as the datasheet sugest.

I want to know if I can split the output to get 2 isolated outputs.

Vin = 120V

The circuit is very noisy and I want to identify why.

    Please contact the transformer vendor for clarification. In the transformer datasheet, the note “Application of the transformer allows for the leadwires between terminals 1&2 and 4&5 to solder bridge”  implies the winding wires may be connected via solder bridge during manufacturing processes. In that case, you cannot use it for dual outputs.

    C16 is too large. Please remove it, or use a different value. A starting point is C=47pF, R6=510 Ohm, but use the datasheet (Page 18) info to optimize the values.

    Please contact your local sales team for more technical support. Thanks!
