- They do not need dividers for both PPD and APD. I assume their adpater is 48V or higher, so we can remove PPD divider. So DNP R7302. They could remove R7302 and R7304 and connect PPD to VSS.
- D7307 has a reverse recovery time of 50ns, whereas the one used in PMP6672 has 25ns. The 50ns delay may be too long to catch the rising edge of the Vds. Therefore a faster diode should be chosen.
- the CS pin has a 330pF cap to help filter the signal. I would advise at least a place holder for a capacitor here. I have found this capacitor can make the difference in stability of the design.
What is the difference between TPS23754EVM-420 EVM and PMP6672. The customer have seen that some materials are different, but the general structure is the same. Is it the difference between the new version and the old version?
The PMP6672 is the optimized version of the TPS23754EVM-420. Sometimes we revisit popular designs and optimize them for efficiency or cost after we do the work of releasing the new IC.
I would recommend following the PMP6672.
