Part Number: UC3825 Other Parts Discussed in Thread: UC3823 Hi TI team
I'd like to know output A & B of UC3825.
Are they reverse each other, or phase difference angle??
Thanks
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 OutA…
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…

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 to…
Edwin,
Can you post the rest of your schematic?
Also what happens if to remove the NAND and IR21844 and drive the main switching FET directly with the UC3823? i.e non synchronous mode for the moment.
Regards,
Richard.
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 who…
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?
Is it depends…
