TPS23730: Device recommendation

Part Number: TPS23730
Other Parts Discussed in Thread: TPS23758EVM-080

Hi,

My customer wants to build a power delivery solution for a PD. The final the design has to be very flat:

  • Height final design <10mm
  • Input Voltage Range  - conform to 802.3 af/ at max 13W
  • What type of input source it is - 802.3 af/ at conform power source
  • 0utput voltage - 5V or 12V or multirail for 1.8V, 3.3V, 5V/ 12V
  • What the output rail will be powering - analog amplifier, DDR2, microprozessor
  • Isolation needed - yes according to 802.3 af/ at
  • Efficiency  >80%
  • Output Ripple <50mV
  • switching frequency  >250kHz

What devices/ reference designs do you would recommend for that.

Thanks

  • Hello, 

    I would suggest the TPS23758EVM-080. I have worked with linkcom to define a new transformer that is less than 10mm. Please email me in TI email and I can send you the spec sheet and required EVM modifications.

    I think another challenge is to ensure the RJ-45 is below 10mm. 

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