Part Number: UCC2817 Other Parts Discussed in Thread: UC2854 , UC2854A Hello. I would like to know if UCC2817 can be used as a direct replacement for UC2854, only with accessory RLC component changes?
I have an application that uses the UC2854A to drive…
Part Number: UC2854 Dear Team,
I would like to know what will be the Multiplier output voltage when Vff is above 4.5 V. Does it will go to zero nor clamped at any particular voltage.
Thanks and Regards

Part Number: UC2854 Dear all,
Our customer is trying to measure the leakage current between 16pin (GTDRV) and 1pin (GND).
Do you measure the leakage current between pin 1 and pin 16 when you evaluate the product?
If you are measuring, I would like you…
Hello,
The way the UCC28065 PFC controller is designed, it can operate long term with one one phase (channel, output) running and the other one not running, however, it always drives both phases at start-up to avoid the risk of CCM in the inductor. This…
Part Number: UC2854 Other Parts Discussed in Thread: TINA-TI , , UCC28180 , UCC28056 Tool/software: TINA-TI or Spice Models Hello,
I'm looking for a spice model for the UC2854 , as it is missing on TI.com.
TINA-TI or PSpice or LTspice would be ok.
Thank…
Part Number: UC2854 Hi team,
My customer has a question on the oscillator frequency.
In the datasheet, there is a min/max value that is given at T=[-40;+85degC].
Do we have a min/max value only at 25degC?
Thanks in advance for your feedback.

Part Number: UC2854 Hello E2E,
I am looking for some clarity. It was noticed in an older datasheet (2008) that the absolute max junction temp was 150C. In the newest datasheet lists the 150C as a max storage temp and a 85C recommended operating but no…
Hi Seshaiah,
Thank you for the query on UC2854.
Please refer page-3 for the following link for the difference:

Dear Harish,
Thank you for your response.
The UC2854 was added as one of the candidates because it can be used in the range of 0-85C. (Not enough for 100C...)
Can UC2854, UCC28180 and UCC28019 be used with 4000W output?
By the way, in the current concept…
