The UCC28180 EVM recommends applying the input AC voltage and then turning on the bias supply, but it should not affect the performance either way. Can you please post some waveforms to indicate the type of failure you are facing?
Part Number: UCC28180 Dear Expert
Vin is 230Vac/50Hz, Vout is set to 408V/850W, Vout has jitter: 380V to 430V,Pin6(Vsense):4.46V to 5.4V. When Pin6(Vsense) rises to 5.0V, the duty cycle slowly decreases, and the Gate will close when Pin6(Vsense) rises…

Part Number: UCC28180 Hello TIer,
I have question about PSDS paper.
as paper mention, may I know the K1, K2, K3 represent which parts factor? there have detail mathematical derivation?
Part Number: UCC28180 Other Parts Discussed in Thread: TLV3201
I'm trying to simulate a PFC Dithering circuit based on the SLUA704 document using a UCC28180 and TLV3201. R4 and C1 are designed to get a dither rate of 2kHz. However, using the given…
Part Number: UCC28180 Hello,
We are making a power supply circuit using UCC28180.
When I made a circuit according to the circuit of EVM-573, the IC does not work at all.
Vcc is 14V input.
the FET is not oscillating because the gata signal is not output…
Part Number: UCC28180 Hello Team,
Can you have a look at the following customer inquiry please?
What could cause the UCC28180 to break?
Now we have three broken units where pin 8 (gate) of the UCC28180 is shorten to GND.
Yesterday we tested PFC stage…
Part Number: UCC28180 Sir,
I am trying to simulate UCC28180 reference design by removing the CCMDCM block and replacing it by MOSFET so as to see internal switching waveform but it is showing convergence issue. I came to know that transient model is derived…
