  • TPS23755: Custom flyback transformer for TPS23755

    Part Number: TPS23755 We are in need of PoE interface with a higher than normal isolation barrier (3kv+). I've reached out to wurth and coilcraft for custom transformers based on the LTD0950 that is recommended for use with the TPS23755. It was mentioned…

  • TPS23755: TPS23755 for light-load application

    Part Number: TPS23755 Hello, I'm evaluating an application where i would need a relatively large voltage span (-15V to +24V) from isolated Power over Ethernet. I was looking at TPS23755 for this role. Due to space constraints, I cannot use the suggested…

  • TPS23755: Alternate Transformer for TPS23755 PoE PD Design

    TI Thinks Resolved
    Part Number: TPS23755 Hi Team, We are currently designing an 802.3at PoE PD for one of our PoE products using the TPS23755 controller. During the design process, we found that the recommended transformer parts LDT0950-50 and 750317728 are currently…

  • TPS23755: LLDP issue

    Part Number: TPS23755 Hi Team, We would like to inquire whether you have a solution for a PoE power allocation issue. Our product is powered by PoE. Inside the system, there is an IP camera powered through PoE, and an AD board driving a 10-inch…

  • TPS23755: damaged issue

    Part Number: TPS23755 Hi, We found TPS23755 damaged and based on our current measurements: PoE_GND and PoE_56V- are nearly shorted, with a measured resistance of approximately 12.5ohm PoE_56V+ and PoE_GND are nearly shorted, with a measured…

  • TPS23755: TPS23755 - Current Peak On The Current Through The Transformer Primary

    Part Number: TPS23755 Hello, I designed a 12V Flyback power supply able to provide a current of 0.3A using the TPS23755 reference. I used a transformer with the following specifications : - Inductance of 155µH ± 10% - Maximum leakage inductance of 3…
