Part Number: UCC28722 Other Parts Discussed in Thread: UCC28720EVM-212 , I'm facing an issue for UCC28722 control which is not starting up when the main power applied. I followed one of the reference design UCC28720EVM-212. I made little bit changes and…
Part Number: UCC28722 Tool/software: I am using UCC28722 for a flyback design and I am using LT Spice as tool.
Downloaded P-spice model and added the sbckt as a symbol.
everything worked fine except the simulation.
I have attached both LT spice…
Part Number: UCC28722 Tool/software: Dear team,
We are designing a power supply using UCC28722. I came across the term "IOCC" is the target output current in constant-current regulation. Which is used to calculate the R.sense resistor.
I skeptical…
Part Number: UCC28722 Other Parts Discussed in Thread: PMP10397
Tool/software:
Hello there,
We have used the reference design PMP10397 as it is except the transformer is changed to below specs.
Vin min=300V DC
Vin max=650 DC
Vout 15V / 0…
Part Number: UCC28722 Hi,
I would like to ask for your guidance on a multi-phase flyback concept.
Target / Concept
Input: AC 40–460Vac (very wide range)
Output: DC 460V (common HV bus)
Concept: Use six flyback converters in parallel…
Part Number: UCC28722 Other Parts Discussed in Thread: UCC28740 Tool/software: Dear Team,
Do you have ACDC parts that can replace MS1001SC A cross-reference search couldn7t yield any part numbers. BR,
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…
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.

If you exceed the abs max rating of UCC28722 the device may not immediately fail. What abs max means is that once it is exceeded, TI no longer guarantees that the device will operate as specified in the datasheet. What could happen is that…
Part Number: UCC28722
Dear sir ,
We are trying to operate the UCC28722 for buck converter design application (380 V Nominal Input and 15V Output ). We have used darlington pair instead of NPN transistors as Switching device .While operating the converter…
