Part Number: UCC3895 Other Parts Discussed in Thread: PMP9622 Hi team i got some questions about the pmp9622 question 1 is the R35 tied to ground( 0V ) or tied to 5V supply. as the figure below. question 2 why is the r28 supplied from 6.3V is there a reason…
Part Number: PMP9622 Hi Support team,
My customer is interested in PMP9622 for their design and they are asking for the transformer datasheet/sepc for RL-10679 used in PMP9622?
Thank you very much.
Best Regards,

Part Number: UCC3895 Other Parts Discussed in Thread: PMP9622 , , TL431 , PMP Hi Team
My customer is curious about the different feedback circuit (EA+ EA- EAO) between PMP9622 and UCC3895EVM-001
why we designed two types of feedback circuit, any different…
UCC28220 is a peak current mode PWM controller that enables cycle-by-cycle current limit as you described: " output voltage gradually decreases. However, the load current continues to increase "
Current foldback as you described with the diagram…
Hi Georges
Thank you for the query on UCC3895.
Can you please refer PMP8740 and PMP9622 reference designs for details on measuring the current in the output using OPAMP.

Part Number: UCC3895 Other Parts Discussed in Thread: PMP9622 , UCC28950 Hi Team,
i have designed a power supply using UCC3895 and its working fine without feedback but as soon as i connect the feedback circuit to the IC it doesn't work, So i am attaching…
Hi Daniel,
I'm did a little research within the TI offerings and noted that TI has a Phase Shift Evaluation board PMP9622, based on the UCC3895 (350 Watt). My thought, I can use this board to get started on a design, enough where I can substitute the…
Part Number: UC1875-SP Other Parts Discussed in Thread: PMP9622 , UCC3895 , , UCC28950 , UC3875 I am designing a Phase Shift Full-Bridge DC-DC Converter. My design needs to be SPACE qualified, so I will use the UC1875-SP. I referencing the "PMP9622A …
Hi Ahmed,
Thank you for the query on UCC28951.
The output capacitor value would be calculated based on load transient, output holdup and ripple voltage as explained in the application note
. The same would go for a battery application as well as per the…
Hi Suttichai,
It is possible to design a PSFB with a constant current output where the output voltage reduces at heavy load. This can be done using CC-CV control using two feedback loops; one two regulate the maximum output voltage and the other to regulate…
