  • UCC28063: : UCC28063D – PFC Not Operating Properly (Current Spikes, Poor Power Factor, and Gate Signal Observation Issue)

    Part Number: UCC28063 Dear Sir, I am testing a PFC stage using the UCC28063D controller along with UCC27524AD gate drivers. Although the circuit is regulating correctly to around 375–400 V DC , the input current is not in phase with the AC input voltage…

  • UCC28063: The temperature characteristic for UCC28063

    Part Number: UCC28063 Hi, We use the UCC28063 for the PFC control, and now, we have the High and low temperature cycling test(-40℃-50℃), but some of UCC28063 is damaged when we finish the cycling test, we have A-B-A testing and the issue is follow…

  • UCC28063: UCC28063 Application problems

    Part Number: UCC28063 HI, TI Team: 1. In the figure, yellow is the UC28063 drive, blue is the inductance input voltage, green is the MOS current, and purple is the input voltage. The two graphs are different positions in a waveform. It can be seen that…
