Other Parts Discussed in Thread: UC3823B Hello,
Actually i design a buck convrter with UC3823B controller.
I simulate my spice design but the converter not turn on.
have you an idea with this probleme.
Thank you
Part Number: UC3823A Other Parts Discussed in Thread: UC3823 , UC3823B Hi Team,
Could any expert help to check if we have any temp related characterization data for pin 9?
Etther UC3823/UC3823A/UC3823B is ok.
Customer is asking, thanks!

Also note UC1823A is a dual output whereas UC1823 is a single output.
As indicated in the datasheet :
The pin configuration of the UC3823A and UC3823B is the same as the UC3823 except pin 11 is now an output pin instead of the reference pin…
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…
Hi Xiaojun,
Your issue is that the output voltage can not be stabilized.
My suggestion is:
1. use the pure resistance load instead of the amplifier load to eliminate the cause of the load.
2. try to lower the bandwidth of voltage Loop to regulate…
