Hi,
I am planning to use the DC-DC converter of this application. When i come across the transformer section i found that the ration is 1: 0.07595 as per the electrical specification sheet. with the same when i calculated, its showing different voltage…
Hi, Mia:
Please refer the figure as below. It may help you understand it easier.
ICHARGE is provided through VBUS, and it is limited by RSU
ISTARTUP is the necessary current to IC to charge VDD.
ICHARGE should be higher than ISTARTUP to make sure CVDD…
Hi Andy,
Same as your point out that the inductance limitation is 200uH to 1500uH by its internal PID feedback loop control, so UCC28630 would not be suitable for your.
I also list down several reference design which similar with your spec for you reference…
Part Number: UCC28600 Hi Team,
As title, my customer survey Vin:600V and Vout:60V1A reference design.
We found http://www.ti.com/tool/PMP5067 (100VDC-650VDC Input 12V 40W Isolated Flyback) but Vout is only 12V.
Tried to run Webench but the max Vin is only…

Our QR flyback controller UCC28600 can work well for this requirement. http://www.ti.com/tool/PMP5067 is a reference design that is close to the design specification with this device.
Best Regards,
Eric
Hi Samrat,
I may have misunderstood your question. For the bias supply you could do an isolated flyback coming from either your three phase input or your DC link voltage. For UCC28950, a nominal voltage of 12V is preferred. Take a look at PMP5067: http…
PY,
Unfortunately to change this design to 600V input would require significant changes. This includes the transformer, power MOSFET and clamp circuit. PMP7958 and PMP5067 can be referenced, though they are for higher power. You can also use TI's Power…
Archit
For your first question, this depends on what the system requirements for the inverter are. For example if there any anti-islanding requirements that require the AC output to be disabled, but the microcontroller still needs to be powered, than…

Hello,all
I want to simulate PMP5067-REVC with Tina,but I can't get the result.
Can anyone help me find the problem?
Thanks a lot

Other Parts Discussed in Thread: UCC28600 Hi
I came across this design from TI for a DC/DC convertor from 650V input to 12V output.
http://www.ti.com/tool/pmp5067
I can't understand how can UCC28600 handle 650V while its absolute maximum input voltage…
