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…
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,
Wei-Hao
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…
Hi Naveen,
The only method I can think of is to implement a circuit that detects the output short circuit event, and pulls COMP to ground to command zero duty.
You can implement a CVCC (Constant Voltage Constant Current) scheme using two op amps in…
Part Number: UCC28C50-Q1 Other Parts Discussed in Thread: PMP9622 , PMP10834 , UCC24612 Hello,
I am testing a flyback converter and observing unexpected switching frequency behavior and very high VDS ringing on the primary MOSFET. Below are the design…
Hi Jon,
This IC only has cycle-by-cycle OCP (Over Current Protection) and does not have hiccup mode feature.
You can try the following:
You can implement a CVCC (Constant Voltage Constant Current) scheme using two op amps in the feedback- where…
Part Number: UCC3895 Other Parts Discussed in Thread: TL081 , PMP9622 , PMP8740 Hello,
I am using UCC3895 in a Full bridge converter 48V DC input, 320V DC output. I want to insert a current regulator on the output with a shunt placed in series on the…
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 which…
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…
