Part Number: TPS2373
Other Parts Discussed in Thread: UCC2897A, , PMP20878, PMP21103, PMP21318

Hi Team,

The TPS2373 datasheet shows a flyback controller that controls two FETs.  Do you know the part number of a controller that operates like this?

Thanks!

    Hi Connor,

    Thanks for reaching out.

    This circuit should be an active clamping forward converter based on the AUX winding design. This PWM CTL IC normally is UCC2897A.

    Below is a table of TPS2373-4 based reference design which may help. 

    Reference PD Topo Class Vout Iout Power
