Other Parts Discussed in Thread: UCC28720 Dear TI people or other very nice helping guys,
For a 1-10V fluorescent lamp dimmer I've selected this device make a flyback converter to power a simple MCU and a few other components. Besides minimal no load…
Other Parts Discussed in Thread: PMP9088 , UCC28720 , UCC28722 Hi,
I would like to know if I could use UCC28720 controller instead of UCC28722 in the "6W USB Charger Reference Design" (www.ti.com/tool/PMP9088).
I know they are not pinout and package…
Hello BR,
The UCC28722 is the same device as the UCC28720 and does not have the internal high voltage startup.
You would use trickle charge resistors to charge up the VDD capcitor.
However, it you want to use the UCC28720 you could use a series pass…
Hi, Sergey
UCC28720 is not recommended to support two output rails in parallel.
I recommend you to change the output voltage of UCC28720EVM to 12V and use Buck stage to achieve 5V from 12V. Then, you can get both 12V and 5V.
BR,

Hello Ras,
The UCC28722 drives IGBTs and is better suited for extremely high voltages and would work for your application.
However, the UCC28701 is designed to drive FETs and will also work for your application.
They both use trickle charge startup. There…
Part Number: UCC28740 Other Parts Discussed in Thread: TL431 , UCC28720 , UCC28600 , LM5023 Hi,
I am having problems with a AC.DC convertor based on UCC28740 5V/3A
My VS is under 4V , CS at around 800mV and switching frequency (1A) around 30Khz
What…
Part Number: UCC28742 Other Parts Discussed in Thread: UCC28720 , PMP8678 The VS pin absolute maximum rating on the datasheet is listed for -0.75V to 7V. Is this rating valid during all operation or only at end of each switching cycle, disregarding beginning…
Other Parts Discussed in Thread: UCC28720 is there a paper for an AC to DC high voltage Flyback Bipolar power supply for DC applications? a 200V?100 till 200mA?
Part Number: UCC28910 Other Parts Discussed in Thread: UCC28720 , PMP9243 We need some help on 3 projects ASAP. All are relating to the UCC28910 and a similar fault condition, operating voltage range. These are all of the products that we’re currently…
