Hello,
To keep the communication more efficient and effective, I suggest to connect with our FAE and they can channel to us directly via other means instead of using this forum.
Thanks,

Part Number: UCC28019A Tool/software:
Hello all,
We are creating a PFC circuit that maintains a 19.2V~24V AC input voltage with an output voltage of 36V.
But Excessive current flows during PFC startup and momentary breakdown recovery.（Please check the…
Part Number: UCC28019A Other Parts Discussed in Thread: LM5157 , UCC28070 Tool/software: Now, I'm using UCC28019A for boost converter up to 2kW (input single phase 220Vac, output voltage 400Vdc).
I would like to increase the output power by parallel…
Part Number: UCC28019A Tool/software: 這是一個輸出200V、0.5A的BOOST PFC電路。我想使用TINA軟體中的功率表來計算功率因數。我在網路上搜尋了很多文章，但大多數都討論交流或直流電路，並且我沒有找到任何專門計算交流到直流轉換的功率因數的文章
輸出功率為98.62W

Part Number: UCC28019A The schematic diagram of the PFC part is as follows.Design requirement: AC220V/50Hz input, output DC 390V 3A, switch power transistor IGBT specification is 650V 20A. Currently, testing has found that the circuit will burn out the…
Part Number: UCC28019A Other Parts Discussed in Thread: UCC28019 , UCC29910 Hi Support team
Do we have UCC28019A but change for BUCK PFC solution, my customer is asking for
thanks a lot
Part Number: UCC28019A hi Sir
I want to design a 1kw power, use the UCC28019A, I use the NTC to Limit the inrush
now ,I need to Add a Relay,in parallel of the NTC, did you have any advise ?
the ic have any pin to control the Relay?
Part Number: UCC28019A The design schematic diagram of UCC28019A is shown in the following figure. During harmonic testing, it was found that the I-THD (%) value exceeded 5%, which does not meet the design requirements. After replacing the inductor, there…
Hi Samuel,
Thanks for the update. I highly recommend getting a current probe as magnetic components are hard to debug without measuring current. If you do not have a current probe available, you can try measuring the voltage across your current resistor…
