Part Number: UC2825 From the datasheets it can be seen that the maximum duty cycle for this part is 80%
I work in voltage mode, open loop and cant achieve more than 50% D.C.
Does the controller really have the ability to work at 80%?
please your advis…
Part Number: UC2825 Other Parts Discussed in Thread: UC1846 , , TINA-TI , UCC28C42 Hi,
I am trying to run simulation on the UC2825, but cannot find its Pspice model, the closest part model I can find is the UC1846, but LTSpice gives an error “Too few nodes…

Hi,
Please, Do you have an SO16 version of the UC2825?
We have the SO8 footprint on the PCB, but its too narrow for the UC2825 which is SOIC16.
Is there any equivalent chip that we can put on the pad?
Part Number: UC2825 Other Parts Discussed in Thread: UCC2818 Hi,
We are doing PFC with UC2818D.We have the following diodes to protect the pins....(anode to GND, cathode to pin)
PKLMT pin has a BAV102 CONNECTED (BAV102, 0.25A, 150V, Switching diode)

Part Number: UC2825 Hi,
In UC2825 datasheet, it shows DO201 Schottky diodes (1N5820) being used to clamp the gate drive outputs to ground.
Will it be OK if we use 1A Schottkys for this instead? (ie SD0805S020S1R0)

Part Number: UC2825 Hi,
I calculate an oscillator frequency of 470kHz with RT=6040R and CT = 560pF with UC2825.
So does this mean that each diagonal pair of the Full Bridge switches at 235kHz?.....and that the switching ripple frequency seen in the output…
Part Number: UC2825 Other Parts Discussed in Thread: UC28025 , Hi
We are using UC28025 today and find that UC2825 is very similar. So I want to ask if UC2825 could work where where have UC28025 and if there is something to look out for in terms of differences…
Part Number: UC28025 Other Parts Discussed in Thread: UC2825 Hi
There was a question raised 4 years ago that was answered. But the last question (six) was not answered in that post. So I attach that question again. I hope the pdf comes in this post.

Part Number: UC2825A-EP Other Parts Discussed in Thread: UC2825 , UC2825A-EP is an improved version of UC2825.
Is this a drop in replacement? I have external clock and RAMP for synchronization of multiple channels.
