TPS2373: Power loss in TPS2373-3

Part Number: TPS2373

Hi,

May I know if TPS2373-3 is a device which would cause power loss within the chip?

For example, for a BUCK converter chip with MOSFET embedded, we think there's power loss within it due to the MOSFET power loss.  But for a BUCK controller chip with MOSFET connected externally, we treat this is as "No power loss" within the chip since MOSFET is not within the chip.

THanks,

Antony

    Hello Antony,

    Every chip dissipates power, and there is a way to calculate this. 

    But the TPS2373 does not have power loss like you described. It is a "PoE PD" only, meaning it does not have a PWM controller in it at all. 

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