TPS2373: FLyback Controller on schematic

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?



  • 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
    TPS2373-4EVM-758 TPS2373-4 ACF 8 5 14 70
    PMP20878 TPS2373-4 ACF 8 24 3 72
    PMP21103 TPS2373-4  ACF 5 12 2.5 30
