Other Parts Discussed in Thread: TPS23756, TPS23756EVM

Hi I am planning to use TPS23756.

While referring the datasheet, i didn't get the use of M4, M3 in the circuit.

Please specify the use of M4 and M3 in that circuit.

    Hi Surabh,

    The datasheet shows a switching converter needed to step down the 48V PoE voltage to a lower output voltage for a load such as 5V or 12V. M4 and M3 switches are needed as part of the switching power supply topology used (in this case, active clamp forward converter) to make this power conversion. I recommend looking at the TPS23756EVM for a known working solution that you can stem your design from.
