TPS23730: Non-Isolated DC-DC Converter to 18V from PoE (i.e. is flyback the only way?)

TPS23730: POE Class 3 24V flyback

Part Number: TPS23730

Hello,

I am looking for a 24V @ approx 2A POE flyback buck solution for the 23730. I found a 50W TI  5V@10A, 12V@5A and love to see a 24V@2.5A design.

Are there any 24V POE class 3 reference designs in your quiver?

    Hello Bruce, 

    Unfortunately we do not have any designs at this output voltage and power level. My suggestion would be to use one of our reference designs that are 24V output and then modify it for 2A (instead of 3). This would involve changing the transformer, but since the turns ratios should be close, the work of changing it would be minimal versus designing your own DCDC.

    We have an ACF and a flyback 24V/3A design. Also i understand it is not with the TPS23730, but the TPS23730 could be used in place of the PD and PWM controller.
