Other Parts Discussed in Thread: PMP22301, , CSD19534Q5A
I am considering creating a circuit using the TPS23754 device.
The specifications are as follows.
I would like to create a circuit based on the reference design PMP22301, but I am also considering the following changes from this design.
I would like to change the transformer to 750314782 for miniaturization.
I will attach the materials.
The inductance value becomes smaller, but is it possible to change the transformer to this?
I would like to add a synchronous rectification circuit using Gate2 to improve efficiency.
I would like to use the circuit of TPS23754EVM-420 shown by the red line in the figure below.
Are there any parts other than the Q1 FET that need to be changed?
I think that the secondary side synchronous FET requires a voltage between DS of about 100V.
Therefore, I am thinking of using CSD19534Q5A.
Could I use this FET?
Also, please let me know if there are any other recommended FETs.
Is there anything else that needs to be changed in order to perform synchronous rectification of Gate2?
