Hello Ilavarasan,
Yes, the inductor ripple current at the PFC switching frequency normally adds Differential-Mode (DM) noise to the EMI signature and this noise is usually seen as a series of tall EMI peaks separated at integer multiples of the switching…
Part Number: UCC28180 Other Parts Discussed in Thread: UC3842 Tool/software: Hi team,
I am currently developing a boost PFC+flyback switching power supply. The PFC chip uses UCC28180, and the flyback uses UC3842.
1. The power supply for UCC28180 uses…
Part Number: UCC28180 Other Parts Discussed in Thread: UCC28019A Tool/software: A typical PFC control chip requires three input values: the rectified input voltage, the sampled voltage of the bus voltage, and the current between the positive and negative…
Part Number: UCC28180 Other Parts Discussed in Thread: TINA-TI , UCC2818A Tool/software: Hi,
I plan to use TINA-TI to verify the UCC28180 Transient Spice Model. In the following thread, there was an answer that said, "It looks like this TINA model is…
Part Number: UCC28180 Tool/software: A typical PFC is directly connected to a Boost inductor after the rectifier bridge. Why does UCC28180 add a 4.7uF capacitor after the rectifier bridge?
Part Number: UCC28180 Other Parts Discussed in Thread: UCC28070 , UCC28019 , PMP22606 Tool/software: Hello Everyone,
I need Ucc28180 IC's Unencrypted lib file. If any one have kindly reply to me or give the tips where it located.
1. Actually, I'm making…
Part Number: UCC28180 Tool/software:
Hello, I recently encountered a problem when testing the VCOMP of UCC28180
Below is my circuit diagram
I tried sending different voltages to VSENSE
When VSENSE=4.5V CH1:VCOMP CH2:VGS(GATE)
When VSENSE=2V
When…
Part Number: UCC28180 Tool/software: I want to output an AC800V/10A (RMS) , bus voltage of 450V using a regular UCC28180, then pass it through a full bridge and transformer, and finally pass it through LC filtering.
Is this plan feasible and reliable…
Part Number: UCC28180 Tool/software: Hi TI Community,
We are using UCC28180DR to control and drive a boost PFC with 400V dc output voltage and 1 kW rating. IC peripherals are highlighted in the image shared below.
We are facing hardware damage issue…
