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 output…

As i check from the dataheet of UC1823A, it has %100 maximum duty cycle of each output.
1) Are two PWM outputs of UC1823A in phase…
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: UC3823A Hi guys,
I am designing a buck regulator for battery charging. I have done quite a lot of testing on my current design and found that it gets unstabile at high voltages and light loads. The controller I use is the…
Hi, thanks for your answer.Please forgive that I take so long to response, there is a problem occured in my email setting and I didn't receive reminder about your reply.
I got a question about your mentioned UC3823A. According to the datasheets, UC3823N…
