Part Number: UCC28782 Other Parts Discussed in Thread: TL103W , Hello:
In a separate application, we need to have our UCC28782-based module behave as a "current-controlled" source. Such that its output voltage will change in accordance with the load current…
robin gangopadhya18 said: Even at 240W, LMG2610 wont exceed its I limit. So is that mode available using UCC28782 controller provided of course the xmfr , SR etc can handle this power all limited to 5A max output?
LMG2610 can handle 240W just fine…
Part Number: UCC28782 Other Parts Discussed in Thread: TPS65987D , TPS55288 , TPS65987 , BQ25730 , TPS2546 Hello:
We have a cool UCC28782 ac-dc circuit finally fully operational up to 100W , 20V output.
Our intention is to productize it for USBC PD AND a…
Part Number: UCC28782 Thank you for your response. Let me ask you one more question.
Please check the datasheet below. It says that the waiting time for SCP（Output short-circuit protection）
operation is less than topp, does less than topp mean immediate…
Part Number: UCC28782 I have a question about the function of UCC28782CD What determines the reset voltage for tFDR restart (1.5 seconds)?
If VDD(RST) falls below 4.3V, will the tFDR restart (1.5 seconds) be canceled?
Part Number: UCC28782 Hello,
I have downloaded the SIMPLIS model for the UCC28782. Without doing any changes to the SCH, I tried to run the simulation and I got the following error:
*** ERROR *** (UCC28782_NA1P0_SIMPLIS_TRANS.net;81): Decryption failed…
Hi Hai Phung,
Thanks for the query.
The free version of simplis is limited in number of available nodes and is not able to run the UCC28782 model unfortunately. You might need 8.2 full version (or higher) atleast I think.

This is a question when the UCC28782 operates in QR mode. I assume that ZCD is detected at the VS pin, but how is the delay time from ZCD detection to PWML output determined?
Is it possible to change the delay time…

Dithering is enabled and a abnormal noise sounds when the load becomes heavy. The abnormal noise sounds seems to be coming from the input/output ceramic capacitors. Please tell me why the tones occur even though the…
