Other Parts Discussed in Thread: TPS40210, UCC28711EVM-160

Hi Team

My customer now has a fly-back selection requirement, the function is described as below:

1. Input: 24V（-15%/+20%）.

2. Output: multiple groups of output (two groups of 20V, one group of 16V/1.8A), with a total output power of 30W.

3. Output requirements meet isolated output.

Thanks

Best Regards,

Hello,

The TPS40210 is design for low input flyback converters similar to your design.

There is a reference design available that you might be interested in.

If you need support on this device please add the TPS40210 part number to the title so the appropriate TI applications team can support the technical questions.

Hi Mike

Thanks for your recommendation.

But I don't understand why you push UCC28711EVM-160 as the reference design for this case. This design doesn't quite meet the design requirement in this case.Could you explain why you push this ?

Thanks

Best Regards,

Hello Wesly,

The link was supposed to be to a 24V in 5V 6A output fly back design using the TPS40210 in a low voltage flyback.

The correct link is a follows. http://www.ti.com/tool/PMP40274
