TPS25740: The reference design of the Flyback with PD3.0 solution

Rock Shao
Expert 2985 points
Part Number: TPS25740
Other Parts Discussed in Thread: TPS25750, PMP11451, TPS65987D

Hi 

I am found the simple flyback with the PD3.0 solution and share it with my customer, and I found the TPS25740 is an easy PD IC, but it is NRND.

May I change the following solution from TPS25740 to TPS25750? Also Can TPS25750 support  5V, 9V, 12V(15V),20V, and 8~100W flyback solutions?

Does TI have any reference design for AC/DC flyback with TPS25750?

Just like the PMP11451 what I need. Thanks.

    Rock,

    The TPS25750 is not a good part to use in this condition.  It does not provide current limt for the output path.

    The best part in our library for what you are describing is the TPS65987D.  It can be paired with a flyback converter to provide the functionality that you require.

    Regards,

    Chuck
