Prashant,
There is a TINA model on TI website under UC3825. See link below.

Where are your getting the Pspice model that you are using on OrCAD?
A third party aesystem also provides pspice models for vairous UC devices…
Hi Sam,
Possibly the UC3823A, UC3823B, UC3825A, UC3825B, UC3823, or UC3825 family of PWM controllers could be considerations depending on how the error signal is created from the two analog inputs since in these controller families both the inverting…
Other Parts Discussed in Thread: UC3825A , UC3825 Hi,
UC3825A is the controller of our buck circuit and the driver IC is ISL6207.
In the application, the input voltage is 20v and the output is 8.4v. the maximum loading is 8A.
During the test, i find that…
gG,
1) Are two PWM outputs of UC1823A in phase?
Response: As highlighted in the datasheet pg.2 UC2823A outputs operate in phase with duty cycle from zero to less than 100%.
2) Does each output have %100 maximum duty with same phase?
Response…
Other Parts Discussed in Thread: UC3825 hi
I have design a push-pull 22v to -/+400v supply @20mA each and is stable but when I load the circuit with op amps producing a 0-250v raster at 1Khz then I get a ripple of 1% on my 400v. I require a ripple of 0…
Other Parts Discussed in Thread: UC3825 Hello,
I'm looking for a spice model of UC3825. Does anyone know where can i find it ?
Thanks

UC3825 is not a charger! is ok for the power conversion but won't manage the charging as a real charger would do...
I reccomend you to add a proper charger stage cascaded to the UC3825, based on UC3906, UC3909 or BQ24450...

Hi Bing
I need a controller who with a vco, not a fase shift because these I have models for, like the UC 3875 and 79, I want to try a resonant pwm with adjustable frequentie like the UC3861 these however are not made anymore, I need a trustable controller…
Thanks John
I searched for the application notes of UC3825, but every time i got the push pull converter using UC3825. Can you send any application notes
With Regards
