Hello Aravind,
The VFF pin of the UCC2818A-Q1 ( and others in this family) do not use a potential divider. The VFF voltage is developed from 1/2 of IAC current mirrored into the VFF resistor and filtered with the VFF capacitor. The VFF and IAC pin functions…
Part Number: UCC28070 Other Parts Discussed in Thread: UCC28065 , UCC28064A , UCC28063 , UCC28061 , UCC28060 Tool/software: Hello guys,
One of my customers uses UCC28070 for their mass-production.
At this moment, they have the following questions. Could you…
Part Number: UCC28061-Q1 Other Parts Discussed in Thread: UCC28061 Team,
This part's recommendede operating temperature range is TA=-40 to 125C.
However, TJ in absolute maximum rating has been specified as TJ=125C in operating.
According to this relationship…
Other Parts Discussed in Thread: UCC28061 Hi,
In continuation of the previous post which I made ("UCC28061: Power MOSFETs blown up sometimes") I want to share the new measurement with you and exploring the possible issue with the MOSFETs in…
Part Number: UCC28061-Q1 Hi,
The PCN is announced for the UCC28061-Q1 .
The content is changing mold compound and die-attach.
Is this PCN affected for Thermal Resistance?
Best Regards,
Kuramochi

Hi Mike, I am not sure whether you read my previous text carefully! As I mentioned even in original FET there was 0.5% failure as well, the FET seems quite ok (Voltage VDS 600V, enough current, avalanche energy is good enough and so on) I want to know do…
Part Number: UCC28061-Q1 Other Parts Discussed in Thread: UCC28061 Hi all Would you mind if we ask UCC28061-Q1? <Question1> In case of one sided-operation(ubnormal phase shift condition), will this pin be high-impedance? <Question2> If Phase Fail…
Part Number: UCC28061-Q1 Hi all Would you mind if we ask UCC28061-Q1? We are sorry that we have some basic questions as follows; <Question1> On the datasheet P15 Figure21, what do KT, KTA and KTB indicate? Could you let us know formulas for KT, KTA and KTB…
Part Number: UCC28061-Q1 Other Parts Discussed in Thread: UCC28063 , UCC28061 Hi all Would you mind if we ask UCC28061-Q1? On our customer's circuit, it tends to increase the difference of phase shift(between GDA and GDB) in case of various input voltage…
