Part Number: UC3825UC3825 dead time is the dead time of the oscillation frequency? UC3825 finally outputs two paths, and the dead zone time of these two paths is 1/2? The dead zone of the oscillator if nothing else is considered, is the dead zone time…
Monika,
Apologies for the late reply. I just came back from a long time bank vacation. Do you still need help on this? After checking the screenshot I do not understand what is the error. The pin configuration screenshots seems to match the pin configuration…
Part Number: UC3825 Hi TI's team:
In the application of UC3825, there is a question need your help to reply.
Does the capacitance of the SS pin participate in the loop response?
Would different capacitance values affect the loop stability?
Thank you…
Part Number: UC3825 Hello:
There is a circuit for Open loop testing of UC3825 in the d/s.
A long time ago, I had witnessed testing of this IC( with Unitrode lab in Irvine, CA)...so I know open-loop PWM generation with complete control over 0-100 % is…
Part Number: UC3825 Other Parts Discussed in Thread: TINA-TI Hi,

I am trying to simulate a spice model of UC3825 IC I have obtained…
Part Number: UC3825B Dear Sirs
I am looking for a UCx825.ZIP file including the pspice model for this switching controller.
Could you plase help me?
Thanks and Regards
Part Number: UC3825 Hi, ti's team:
Good day.
There is a question when i apply the UC3825 for a flyback circuit.
I connected the SS pin to ground with a 0.1uF capacitor, but when I turned on the power supply, I still found a large overshoot. My question…
Part Number: UC3825Uc3825 has the minimum duty cycle limit, such as 5%. If the duty cycle is less than 5%, the duty ratio of the chip output may become 0. I want to know the principle.
Part Number: UC3825 Hi, We are using UC3825DWTR in a DC-DC converter. The converter consists of MOSFETs full bridge operating from 380V DC feeding transformer primary. The transformer secondary is center tapped with diode rectifier followed by filter and…
Part Number: UC3825 I want to design 20kHZ, 250W transformer. Where do i get this or is there any code for transformer design so that I can design the core values on my own?
