Part Number: Hi Expert,
The engineer is asking how to run the UCC3818 into the open loop mode.
They are thinking to inject a DC level into CAOUT pin.
Then PWM width can programmed by the this DC level.
Pls advice whether this is workable or not.

Part Number: UCC3818A Other Parts Discussed in Thread: UCC3818 Hi Expert,
The engineer would like to consider to leverage their mature AC-DC design that adopted the UCC3818 inside for 220VDC to 380VDC input applicant instead.
The difference is one from …
Part Number: UCC3818A Other Parts Discussed in Thread: UCC3817A , Hello,
What is the Abs Max voltage allowed on the CT pin? I don't believe I see it in the datasheet.
Thanks,

Part Number: UCC3818A Other Parts Discussed in Thread: UCC3817 Dear Team,
Here is Kevin from Delta Taiwan team.
Customer is testing UCC3818A, it seems during startup the DRVOUT pin will have some driving signal.
Do we have more information explain this…
Part Number: UCC28070-Q1 Other Parts Discussed in Thread: AMC1302 , UCC28070 , UCC3818A , UCC28060 Tool/software: Hi
I'd try the Three-Phase Semi-Bridgeless PFC Topology Using UCC28070-Q1 (Analog IC).
The principle is using the isolatedhalf sine wave…
Part Number: UCC3818A Other Parts Discussed in Thread: UCC28070A , UCD3138 , UCC28070 Hi
I'm Andy from Taiwan.
We try to design a dual AC input PSU.
The AC could be independent or two phases of three phase AC.
Do you have any suggestion??
Thanks.
Other Parts Discussed in Thread: UCC3818A , UCC3817 , UC3854 , UC3854A Can you offer a difference table between UCC3854A and UCC3818A! it's much easy to compare it and know the main benefits on new one of UCC3818A. Very thanks.
Part Number: UCC3817A Other Parts Discussed in Thread: UCC3818A Hello guys,
One of my customers is evaluating UCC3818A for their new products.
They tried to read TI MathCAD file TI prepared by MathCAD trial version because they want to adjust some peripheral…
Some basic chip functionality differences are,
1. UCC3818A uses trailing edge PWM modulation where the UC3854A/B uses leading edge modulation.
2. UCC3818A uses inverted current amplifier feedback where the the UC3854 uses non inverting amplifier feedback…
