Part Number: UCC28060 state:AC1Φ2W Vin85V DCout 386V 1.42A
An incorrect gate signal is output from around the input current of 7.5A, and there is an abnormal noise.
When you check the waveform, it is on continuously. 2ch.Q1Vd-s,3ch.Q2Vd-s,4ch.Input…

What is the role of D3 in Figure 30 of the IC data sheet?
Some evaluation boards are not included depending on the design.
Part Number: UCC28060 Other Parts Discussed in Thread: UCC28063 , UCC28064A , Hi,
I'm using the UCC28060 in one of our power converters application and have noticed that VREF varies with temperature by about 270mV when our product is about 50°C ambient…
Part Number: UCC28060 Other Parts Discussed in Thread: UCC28070 Hi
I'd like to understand/study the calculation/Mathcad of interleaved CRM and CCM PFC.
Could anyone tell me where I can research and study them?
Thanks
Part Number: UCC28060 Other Parts Discussed in Thread: UCC28061 , , UCC28063 I have a prototype 500W PFC using the UCC28061. Operation at light load is good at low mains but very chopped at high mains (>180V). PFC only barely runs continuously with 25…
Part Number: UCC28060 Other Parts Discussed in Thread: TL431 Hi,
I built up the circuit from SLUA625, Fig. 15, but it does not work correctly. I noticed that the auxiliary coil for T1 was not labeled correctly (should be ZCDA, not ZCDB), so I corrected…
Part Number: UCC28060 Other Parts Discussed in Thread: UCC28070 , UCC28180 Is the UCC 28060 operable with DC 180 V to 800 V input?
The output voltage setting is DC500V and the output power is 1kW.
Please tell me why it is possible to operate.
Part Number: UCC28060 Other Parts Discussed in Thread: UCC28056 Hi All,
We setup the controller as calculated in the SLUC072B it will be a 600W converter.
As the unit goes above 300W the second stage is switched on. But the second switch is not switching…
Other Parts Discussed in Thread: UCC28060 Hi,
on document SLUA625, page 17, maximum on time is calculated to be 7.12uSec. it demands that KTL be 1.5x10^-6 as Tonmax=KTx4.825 from UCC28060 datasheet page 17 eq5. based on KTL=(RTSET/133k)*4 (UCC28060…
