Part Number: UCC28950-Q1 Hi expert,
In DCM mode, when output inductor current reverses, how will it influence SR FET? How is reverse current loop constructs?
If not entering DCM mode with SR FET always enabled, what will be the influence?
Is there any…
Part Number: UCC28950-Q1 Other Parts Discussed in Thread: UCC28950 Hi E2E, Good day.
Our customer would like to test the different delay settings in the UCC28950-Q1 without the power stage configuration. Are all pins necessary to be connected? What pins…

Part Number: UCC28950-Q1 Other Parts Discussed in Thread: UCC28950 Hi,
For UCC28950-Q1 there have two parts UCC28950QPWRQ1 and UCC28950TPWRQ1, and there only a temperature difference in the datasheet.
Although most SPEC parameters are the same as UCC28950…
Part Number: UCC28950 Hello, I am working on a design similar to the reference one, but with 24V 25A output.
I had Vbias ON in the control circuit and looking on an oscilloscope at the rectangular signals from the FET gates. After that, when I connected…
Part Number: UCC28950-Q1 Other Parts Discussed in Thread: UCC28950 , UCC28251 Hello all,
my customer want's to use the current transformer as described in the UCC28251 data sheet also in the switch note from the UCC28950.

Part Number: UCC28950-Q1 Hi,
I have some questions for IDD.
Fig5 of the datasheet P11 shows 3.7A of current consumption for IC itself is correct?
The datasheet P6 shows SUPPLY CURRENTSのIDD TYP:5mA、MAX:10mA.
Why it's different from 3.7A and max 10mA?…
