Part Number: UCC28C44 Other Parts Discussed in Thread: UCC27714 , UCC28C54 Hi team,
Background: We are considering two 500-W converter stages using UCC28C44. To avoid audible beat noise caused by oscillator frequency mismatch, we would like to synchronize…
Part Number: UCC28C44 Previously, the UCC28C44 chip worked normally. However, for the newly purchased batch of chips, it was found that the chips had PCN, and the width of the copper wire for wafer epitaxial growth changed from 0.96mm to 0.8mm. Tests…

UCC28C44-Q1: Field failure of UCC28C44QDRQ1 - Power management forum - Power management - TI E2E support forums
We are still seeing failures when using the UCC28C44QDRQ1 at the…
Part Number: UCC28C44 We are seeing some failures of this IC. I need to find out some technical information if the component sees Vdd voltages above 20v. will it degrade and time to failure. I tried to go into their website and log in, but I was not able…
Part Number: UCC28C44 Hi team,
My customer is using UCC28C44 in AC drive application.
They find that UCC28C44 will be 100C degree and shutdonw the output.
Could you please help check the schematic and figure out the reason.
Part Number: UCC28C44 Tool/software: In the Datasheet of the UCC28C44 the example shows a blocking capacitor to remove DC offset when generating a ramp for slope compensation.
The Cramp removes the DC offset and the signal appearing at the CS pin…
Part Number: UCC28C44-Q1 Hi Team,
Posting on behalf of our customer.
I'll share this E2E post with our customer so he can reply when needed.
I have a field failure of UCC28C44QDRQ1 that I need technical support with
I have at least 13 confirmed…
Part Number: UCC28C44-Q1 The maximum VDD voltage at pin 7 of this IC is specified at 20V.
What is the reliability (MTBF) number if the voltage is slightly exceeding 20V in the application?
Part Number: UCC28C44 Hi team,
My Customer meet two failure case of UCC28C44 in AC drive products.
Failure phenomenon is IC can not start up successfully.
Input current is already 3mA when start up voltage is not up to 13.5V threshold, which is…
