Part Number: UC2825 Other Parts Discussed in Thread: TL431 , UC1845 Tool/software: I am using a push-pull converter with the UC2825 PWM controller , but I currently don’t have any input protection or surge protection in place. Instead, I plan to implement…
Part Number: UC2825 Tool/software: Hi
we are testing our switching rectifier in climatic chamber. UC2825 is generator of PWM to the mosfet H bridge. Rectifier is switche on but without any load. We rise up temperature of the chamber at 70° and we noted…

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: 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…
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 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…
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…
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…
