    Hi Swapnil,

    Do you mean the power loss calculation?

    We do not have a document cover all TPS23755 power dissipations. We did the thermal test under the below condition. The chip top case temperature is 56.5C. Consider 34.7C/W J-A thermal resistance (no heatsink, natural convection), the power is about (56.5 - 20) / 34.7 = 1.05 W.  

    • TPS23755EVM
    • natural thermal convection
    • measured after 10 mins
    • 12-V 1-A output
    • 48-V PoE input voltage
    • 250-kHz switching frequency
    • 20C ambient temperature

    Best regards,

    Diang
