Part Number: TPS23756 Other Parts Discussed in Thread: PMP40514 , Hi,
We have made a design using TPS23756. The design was made with the help of the following documents: SLVU329A, SLVA305C, PMP40514, PMP6659, SLVA306A. So the final design is a bit of a…
Part Number: PMP6659 Dear Sir,
Can the PMP6659 reference design support an output voltage 12V / 2.5A @ 11V input voltage? Which components need to be replaced?
Best Regards,
Sam
Part Number: TPS23756 10.8-57V POE power supply Using the ti TPS23756 ,PMP6659 program, pcb do small, component parameters such as schematic, now the problem is ripple, ripple screenshots in the annex. Please reply as soon as possible. Thank you

Hi , I have a question is TPS23756PWPR application. In the PMP6659 evaluation schematic have a MOSFET ( Q6 ) and serial Resistor ( R14 ) I don't understand these component functionality. Is someone can help to explain for me? Thanks for your help. …
Hi Michael ,
We have an additional input External 24VAC and want to output 12VDC through the TPS2375"4" ,But because of the transformer need 33~57V
Not sure it can be used , not PMP6659

Hi Jack,
TPS23756 & TPS23754 are CCM. They both support flyback.
Reference design example: http://www.ti.com/tool/PMP6659
What is output voltage, output current, and input voltage range? I can recommend a reference design for your specific design…
Hello Kai,
Reverse polarity block will disconnect RTN from GND only when voltage at IN pins is negative. RTN pin in TPS2660 has different function than RTN pin in TPS23756.
In this application, reverse current blocking function (RCB) in TPS2660 would…
Hi Gordon,
TPS23754 is not the same as UCC2897A, you can not use SLUC662. for a reference , you can see the reference design PMP6659, which is used the series of TPS23754.
Can you please create a new post with TPS23754? In this way you can find the right…
Hi BJ,
The simple answer would be to adjust the APD voltage divider resistors to hit the rising threshold at the lower input voltage, however significant changes would need to be made to the power stage to allow wide Vin operation.
Instead, I suggest…
