Hi experts,
After the first single interrupt or safe state related comparator on the full path and test, IF.ABIST and IF.MON bit are both set. However, ABIST_CTRL0.STATUS = 5, ABIST_SELECTx = 0 and the corresponding bit in the MONSFx register is set , which seems right.
What is the reason for this?
Thanks

いつもお世話になっております。
Gen3のCoolSETに関して、1点確認させてください。
【確認事項】
Gen3製品に関して、フィードバック構成は非絶縁構成でも問題ございませんでしょうか?
Gen5に関しては、VERR端子があり、内蔵しているエラーアンプにつながっているため、非絶縁でも問題ない構成になっております。
しかし、Gen3ではVERR端子がないため、フィードバックの構成としては推奨は絶縁フィードバック構成になりますでしょうか。
非絶縁で構成できる場合、別で外付け回路が必要になるかと考えております。
Infinoen様として非絶縁構成でも問題ない場合、推奨される回路等ございますでしょうか?
お手数おかけいたしますが、ご教示頂けますと幸いでございます。
Show LessI am using TLF35584 and TC399XP.
I'm thinking of setting the TLF35584 to Standby and setting the TC399XP to Standby as well.
It has been confirmed that the TLF35584 is in the Normal state.
As soon as WAK is set to Low and TLF35584 is set to Standby via SPI communication, ROT becomes LOW and TC399XP is reset.
TRDEL has set the maximum 1.6msec.
Do you know the reason why TLF35584 does not go into Standby and what to do about it?
In the attached photo, yellow is ROT and blue is WAK.
Show LessHello everyone!
I have 2pcs EVAL_3K3W_TP_PFC_CC boards and after the first power-up, both of them have unstable output voltage! It should be around 400V, but it bounces between 405 to 440V. This measurement is made with and without load and has the same final result!
At this link, I have made videos in the two cases with waveform measurements at the output: https://drive.google.com/drive/folders/1etVP54MyFwrMpfUXj3C86bZTQ1oehTcS?usp=share_link
If you listen to the video with the sound on you can clearly hear how the board starts humming when boosting the voltage and stops whit the wave drop!
I have lost a month waiting for support to help me solve this issue and I will be very grateful for any additional assistance. I have a dead-end by the 27th of May to finish my project and everything relies on fixing this!
Thank you in advance!

Show LessCan i combine the programming port with the debug port for the Wlc1115 because i cannot use all the pins
Hello, I am using ICE2PCS02GXUMA1 in my PFC design where input power requirement is about 750-800W.
In my design, the PFC IC shuts down, once I cross about 525W at the input power. Once the load is reduced, the IC starts to operate again.
Schematic is attached.
Any help would be greatly appreciated.
Thank you,
Arun
Show LessHi, I am new to this space and I am trying to operate ICE3PCS01G PFC controller IC. This is my first Power Electronics project, and I am not able to vary the pwm signals at the output of the IC. Even if I vary the VSENSE voltage, it does not vary the output PWM pulse at the GATE pin. Are there any other necessary input voltage which are to be given in order to vary the PWM pulses at the GATE (output) pin? Thanks
Show LessHi,
Could I request for TLF4949SJ PPAP?

In the non-isolated flyback circuit example of Gen5 ICE5xSAG and ICE5ARxxxxBZS, can Wa and Wp1 of the auxiliary winding be used as one?
I think I can insert a diode to split the VCC and FB paths, and the voltage required for FB can be adjusted with a resistor.
Please let me know if there are any disadvantages to using both auxiliary windings.
