Part Number: TPS23754 Other Parts Discussed in Thread: PMP6812 , Hi team,
Could you help me to check these questions?
1) What reference design is the attachment from?
2) Are you have any concern if the power inductor changed to 1uH 3.0A and the info of…
Part Number: TPS23754 Other Parts Discussed in Thread: PMP6812 Hi team,
Could you please help check the TPS23754 circuit as attached?
It's followed by PMP6812 and do you have a recommend TI NMOS part with the TPS23754 for this application?
And what…

Hi Kay,
This might be the feedback circuit. I recommend using the "A" version of the EL357. The current looks high through the opto as well as we typically will design with 2k for R275 and R278.
Any particular reason these were changed from…
Hello Rahul,
Try increasing R333 and/or C449 to increase the RC time constant of the soft start circuit so the ramp time stabilizes.
Check out page 33 & 34 of the TPS23754 datasheet for more explanation: www.ti.com/.../tps23754.pdf
For an example…

Hi Michael,
Looking at PMP6812. There is still more changes that need to be done on the converter. One of the diodes needs to be removed on the VC circuit and add a series resistor, the diode on the secondary needs to be flipped for example. Also, the…
