Part Number: UCC28C43-EP Other Parts Discussed in Thread: UCC28C42
Hello everyone,
Can someone tell me what is the difference between UCC28C42 and its EP version?
Can I safely interchange those two in already on-market products?
Part Number: UCC28C43 Hello, I would like to know if in the UCC28C43 "absolute maximum ratings" table, the values are valid only with VDD present (and therefore VREF=5V), or also without power supply (i.e. VDD=0) In our application the CS pin…
Part Number: UCC28C43 Tool/software: This product is used to boost the working mode, the boost value is 44V, after loading the product in this batch of products in the under-voltage opening of the output superimposed 5V triangle waveform, previous batches…
Part Number: UCC28C43-Q1 UCC28C43QDRQ1's datasheet suggests that the RT resistance should be configured above 1kΩ.
However,we have using the RT/CT combination of 820R/1nF to produce a square wave with a duty cycle of 50% at 1MHz.
I hope to confirm…
Part Number: UCC28C43 Tool/software: Hi, TI
Could you please tell me about the formula of maximum duty and CT. I want to know the formula expressed the figure 15 of datasheet.
Specifically,I want to know the capacity value of CT setting fsw=50kHz and…
Part Number: UCC28C43 Hello,
The datasheet for the UCC28C43 since PCN 20221216002 specifies a minimum value for for COMP VOH to be Vref-0.2V.
1. What is a typical or maximum value for this. Can you confirm that the maximum voltage is now 5V from the…

Hello,
So it is about the behavior of the output of the Error Amplifier (COMP Pin1).
Previously, this output went to a voltage above 6V (data sheet typ. 6.8V) and when it was held at 5V according to the data sheet…
Part Number: UCC28C43 Hello,
We have entercountered come issue on an finctional tester with our assembly that goes thru finctional tester. This problem occured once we started using components after PCN20221216002 implementation.
The main concer now is…
