Part Number: UCC28C45-EP
Hello Team,
For using this part to drive a FET on the primary side of a transformer. Would you recommend having an RC filter on Pin 6 of this part? The Current Sense Pin. see in the Datasheet on page 10 there is an RC on Pin 6…
Part Number: UCC28C45-Q1 Other Parts Discussed in Thread: UCC28C45 , TL431 Dear TI,
I am currently prototyping a flyback converter design using an UCC28C45QDRQ1 controller in voltage mode at a switching frequency of 500kHz. I noticed the converter works in…
S,
I'm glad you have the simulation working and are able to make changes and see the model behaving as expected. This thread is getting long and moving into another topic so I am going to close it as resolved. Please open a new E2E thread if help is needed…
Part Number: UCC28C45-Q1 Hello,
I have just got doubt whether can I use Active clamp topology in 800W to 1KW application?
All the literature says Active clamp forward can be used up to 500W.
Lets discuss in the forum what are consequences (pros & cons…
Part Number: UCC28C43 Hi All,
I think this MPN looks good for an isolated DC/DC design. The Vin = 18-48V, Vout = 12V, I out = 2.5A. I want voltage control instead of current mode control.
Does anyone have any general feedback on this MPN selection for…
Part Number: UCC28C45 Hello,
I am interested by the solution with capacitor and Zener in parallel to create a negative bias on the MOSFET gate to avoid cross conduction.

Part Number: UCC28C45 Hi there,
My customer wants to use OPTOCOUPLER to do secondary side feedback with UCC28C45, like shown in the picture below.
i am working on the maximum optocoupler current calculation.
two quick questions here:
1. how much source…
Part Number: UCC28C45 Hi,
since both device's absolutely maximum temperature are 150C.
I wonder why do we have different parameters for recommended operating conditions?
Is it just because we test our Q version device under 125C, but we only test…
Part Number: UCC28C45 Hi,
Our customer is testing UCC28C45 and they want to confirm the highest frequency of the oscillator synchronization.(What is the maximum synchronization frequency that can be supported?)
For example, if a signal generator is used…
