Part Number: PMP7246 Other Parts Discussed in Thread: PMP , MSP430F2274 Note: The form required me to select a TI part number from the dropdown, but PMP7233 is no longer listed . I therefore selected another PMP reference design only so I could submit…
Other Parts Discussed in Thread: PMP7246 , UCC28950 Dear
My customer is very interesting in TI Design PMP7246 now.
PMP7246 is very useful to make board for My customer.
My customer is planning to make board using UCC28950.
To make board, my customer…
Hi Eileen,
The LM5039 is simply a half-bridge controller for a half-bridge power stage. The power requirement will come from the main components in the power stage such as your choice of FETs, capacitors, transformer, etc.
The only compatibility you…
Part Number: UCC28950 Other Parts Discussed in Thread: PMP7246 Hello,
May I ask for more detail on ' two quadrant converter' and 'backward in average current mode limitation' of UCC28950? I'm looking at PMP7246, but I cannot find any relevant information…
Part Number: UCC28951 Tool/software: Project Specs: Vo: 24VDC Vin: 550V P=500W I am using UCC28951 (PSFB topology) IC for DC-DC isolated power supply project. I have a full bridge synchronous rectifier on the low voltage (secondary) side instead of a…
Hi Venkatesh,
I am afraid you need to add snubber on secondary side, due to the fact every transformer has leakage inductance.
This leakage inductance is generating lot of loss if not properly snubbed.
You can see it in the voltage of all rectifiers…
Hi Rajesh,
Below are my responses to your query
rajesh Gudimani said: Is UCC28951 suitable for replacing ISL6754 in this application?
Yes, UCC28951 is functionally suitable as a replacement for ISL6754. Both are phase shifted full bridge (PSFB)…
Hi, Sanghyun,
Do you have to keep the same transformer and snubber cap or you are open to change the power stage?
I am not sure where you read UCC28950 is not efficient when input voltage is low. 48V input is not low. Can you point me the source of…
Part Number: UCC28950 Other Parts Discussed in Thread: PMP7246 Hi,
I see in the PMP7246 ref. design that they are using "BSC057N08NS3" MOSFETs. Those are in a SuperSO8 package.
This is my first time using that type of package in power applications…
Hi, Alex
Sorry for confusing you, the reference design PMP5726 and PMP7246 shows the Phase shift full bridge can support 2 quadrant application. The output current could be reverse when output voltage is decreasing linearly.
The reference design PMP5726…
