Hi Amal,
You have to find what potentially could cause this issue. One thing I suspect is probably the on time current limit could be hit causing the voltage to drop. Also you might want to check if inductor current runaway protection where Ton < Ton_to…
Part Number: PMP11302 Other Parts Discussed in Thread: TIDA-00940 Tool/software: Hi,
I have come with a pi-filter at the input for noise suppression for my PMP11302 Re-design. With the help of TIDA-00940 i have calculated the values and happy to inform…
Part Number: PMP11302 Tool/software: hi,
My concern is regarding the power rating of the diode used in the PMP11302 design.
The diode D2 connected across the FET Q1 in the design clamps the voltage to 12V in the design.
But my concern here is do we really…
Part Number: PMP11302 Other Parts Discussed in Thread: UCC28881 , Hello Team,
I'd like to know if it is possible to do the same operation with an input voltage of 1100V instead of 900V.
If yes, what component would need to change ? As the circuit clamp…
Part Number: PMP11302 Other Parts Discussed in Thread: UCC28881
Hi,
The reference design PMP11302 claims to operate within a voltage range 166VAC to 528VAC. I would like to know if by making the proper adjustments I can increase the max voltage up to 690V…
Part Number: UCC28881 Other Parts Discussed in Thread: PMP11302 , Hi Experts!
Reference design : PMP11302:
http://www.ti.com/lit/df/tidrk45/tidrk45.pdf
mentions that the maximum input DC voltage connected to the drain of UCC28881 is 914V whereas this part…
Here is the design I thought about, it's a mix between PMP11302 and pmp11090. The PMP11302 input regulates the voltage to around 500VDC and the pmp11090 allows conversion without overheating the controller since the mosfet is external and can be easily…
Hello VT,
I suggest that the PMP11302 concept shown in the trainging pdf can be extended to your 600Vac input. Single phase or three phase rectified voltage ends up with the same peak value with respect to Neutral. Higher if phase-to-phase rectified…
Part Number: TIDA-00940 Tool/software: Hi,
TIDA-00940 has a pi filter at the input.
I am reusing this circuit in my design but i am curious to know how the voltage rating of the inductor impacts the inductor chosen in this design.
Most cases we don't…
