SN6507-Q1: Is it impossible for SN6507-Q1 to work with a Super Tiny Signal Transformer with PoE+

Part Number: SN6507-Q1
Other Parts Discussed in Thread: SN6507

Tool/software:

Requirements:

      1.The fixed input voltage is 24V;   

      2.Output voltage 15-24V, Output Current 50mA.

Is it impossible for SN6507-Q1 to work with this Super Tiny Signal Transformer with PoE+: 74930120 Datasheet WE-STST Super Tiny Signal Transformer with PoE+

Thanks.

  • Hello,

    Can you please clarify "Output voltage 15-24V". Are you planning to design a variable output?

    The push-pull transformer needs to meet required turns-ratio and V-t product.

    SN650x devices are push-pull transformer drivers and the push-pull topology doesn't have a direct dependency on primary inductance of a transformer as a design parameter. The design requires input voltage, output voltage, output current and switching frequency as input parameters and based on these, the SN650x Transformer Parameter Calculator produces the minimum required turns-ratio and V-t product for the transformer. As long as turns-ratio and V-t product requirements are met, the transformer is going to produce the output according to the design inputs.

    The primarily inductance of the transformer can be anything that the transformer vendor requires it to be to achieve the required turns-ratio and V-t product.

    The datasheet Table 9-3 shows recommended transformers for SN6507 that are commercially available. These part numbers or equivalents are optimized for use with SN6507.

    Thanks.
