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…
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 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…
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,

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…
Part Number: UCC28061-Q1
Hi all Would you mind if we ask UCC28061-Q1? Our customer measured the phase shift as follows input condtions; <AC input condtions> 100V(85V~132V) : 176~180 degree(it seems OK.) 200V(168V~264V) : 183~200 degree(it seems that…
As explained, when the COMP voltage exceeded 222 mV, both GDA and GDB output pulses.
[that is because at no load condition if the Comp Voltage is lower than 222mV, then both GDA and GDB will stop the pulse. And at this condition,
GDB output some pulses…
