TPS23756: 12V application

Part Number: TPS23756
Other Parts Discussed in Thread: TPS23730, TPS23731,

Dear team

If customer would like modify TPS23756EVM to 12Voutput. Would it be possible to offer us other reference material or suggestion? 

Which component will need to modified?

Many thanks

    Hey Denny, 

    We have a few reference designs that would cover the input range and output voltage/power.

    However, neither one is an active clamp forward. One uses the TPS23756 and is a driven sync flyback. The other uses the TPS23730 (could use the TPS23731) and is a PSR diode flyback. 

    I can send you both in private email. 

    Directly changing the EVM would require changing the transformer, secondary FETS, secondary gate drives, secondary snubbers, output cap, output inductor, feedback, and sense resistor. However, I have not heard of a wide-Vin 12V ACF transformer, so you may need to define a new one. 

    If this post answers your question, please indicate so by marking this thread as resolved. Thank you.
