Note that 50% duty cycle applied to each channel A or B. Not both A and B.
I used UC3825 for push-pull where duty cycle actually goes to 95% depending on slope compensation adjustment. Datasheet may need to clarify this meaning.
I have not used UC3823…
Other Parts Discussed in Thread: UCC28051 , UCC28501 , PMP30446 , UCC23313-Q1 , UC3823 Hi Team,
We would like to ask your help regarding the customer's inquiry below.
I am looking for a controller for switching a buck converter (or a syncron converter…
Greetings Tobias,
Since you already have your power stage with drivers designed, take a look at the UC3824. -Current mode control -complementary outputs suited for synchronous buck designs -ability to synchronize the clock -adjustable deadtime between…

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…
Hello Richard,
I am grateful for your pertinent remarks.
1. I have in effect located R11 and R12 close to the UC3823
2. You got me thinking here... I need to learn how to apply compensation here. Seems a bit complex. Reading about it. Meanwhile, any rapid…
Hi, all
I am working on a project that requires a PWM signal to drive a DC-DC converter. We want to use the IC in the subject line to generate the PWM signal, but I am not sure how to use the inputs, and I was hoping to get some advice from someone…
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…
Dear hong huang;
Thank you for kind expaination.
I want to make a DC-DC convter with power more than 10 kilowatts.
Ucc39002 can be applicated with ucc38950?
What do you think how many ucc28950 can be paralleled with interleaving method?
