Part Number: TPS23753A

Tool/software:

Hi team

According to the specification, it only supports at type 1, with a maximum power of 12.95W. As the power consumption of the model increases, a 25.5W chip is needed. This chip claims to be at, what is the maximum power it can support?

    Hi Dane,

    Thanks for reaching out!

    The TPS23753A power rating is decided by 350mA RTN current rating.

    You can use a 63.4 Ohm at the CLS pin and get a successful handshake with a Type-2 PSE as Class-4, and the PSE may set the power/current cut at Class-4. But if the RTN current is higher than 350mA, it is out of the rating of TPS23753A. So it is more recommended to use TPS23753A in Class 0-3 cases. 

    Best regards,

    Diang
