Part Number: UCC28722 Other Parts Discussed in Thread: PMP7668 , Hello,
We want to use UCC28722 to create a non-isolated auxiliary supply of 6W for our PFC after reading your document SLUA721A. Given our Ipeak for the BJT is slightly high. We wanted to use…
Part Number: UCC28722 Dear Sir/Ms.
The following are the problems encountered by the customer UCC28722 during testing.
Input DC24V Output DC23V Power 20W When the power is turned on, the output voltage is abnormal, and a triangle wave between 21V and 7…
Part Number: UCC28722 Other Parts Discussed in Thread: UCC28704 , Hello,
In the datasheet it is given that Vccr is 330 mV. I want to understand if this a calculated value or a fixed reference for CC mode of the CS Pin voltage. Vcst (max) is given as 780mV…
Hello Arun,
I'm sorry it took so long for me to get back to you on this issue.
Here is what was found:
It looks like the subcircuit "one_shot" is declared twice in the larger model. This should not be done in any Spice simulator.
The initial…
Part Number: UCC28722 Hi
Regarding 28722 the capacitor on VDD pin is mentioned is slau721a is 4.7 mfd, if I reduce to 2.2 mfd which parameter I should check so that functionality of UCC28722
should not get affected.
