Hello, Thank you for your advices.
Output voltage dipping issue was solved by increasing input capacitance 100uF to 220uF (added parallel 120uF to original circuit).
blue: original output yellow: improved output
Regarding The high frequency output ripple…
Part Number: UCC28C43 Other Parts Discussed in Thread: UCC28610 There are 2 different Cin capacitance calculation of UCC28C43 and UCC28610. Could you tell me the difference between them？ Thanks！
Part Number: UCC28610 Other Parts Discussed in Thread: UCC28600 , LM5023 , UCC28711 , UCC28701 Hi TI team,
My company is looking for QR flyback IC and wants me to search for some useful solution, and I read some documents from TI.
I have some questions…
Part Number: UCC28610 Other Parts Discussed in Thread: TL431 Hi, TI expert.
The customer used UCC28610 to configure the circuit.
TL431 is applied to the secondary feedback stage and the output voltage is set to 15V, but it is said that the output voltage…
Part Number: UCC28610 Hi Team,
UCC28610's FB pin sinks current from opto-coupler, so the FB current should highly depend on opto-coupler's CTR, is there any way to calcaute FB pin current?
Besides, according to datasheet, the absolute maximum rating…
Part Number: UCC28610 Dear Champs,
For UCC28610, is there a way calculate the bulk voltage when the device start to work?
We understood the working is determined by the voltage on Vdd pin, but is there any way to calculate the bulk voltage at that moment…
Part Number: UCC28610
What are all the modifications required to use the above control circuit for 440VAC.
Mosfet, transformers will be selected according the rectified pk voltage.
Kindly suggest for thr required modification in the control circuit part…
Part Number: UCC28610 Hi,
I currently use the UCC28610 in a 16.5V 45W module, and was hoping to use the same controller for a new multiple-output module I am designing, with +60/+20/0/-20/-60 rails and a total 42W output power.
However, I notice that…
