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…
Part Number: UCC28C43 Hello.
We've been using the UCC28C43DR regulator on our boards since many years. Now we have received the first reels of this component according to PCN# 20221216002.1
According to the PCN there should be no functional impact…
Part Number: UCC28C43 Hi
Is there any change in the CS pin voltage of the UCC28C43 newly delivered after the PCN below? When tested with the new product, the current is 5-10% lower than before. Please check if it's related.

Part Number: UCC28C43 Dear TI team,
I am observing pulse narrowing in the output gate signal of UCC28C43DR IC.
For which I have probed following signals
1. Gate pulse and Sense pin voltage
2. Gate pulse and COMP pin voltage
I found no issues with COMP…
Part Number: UCC28C43 Hello,
UCC28C43DR is used in one of our medical assembly. During latest production run, we noticed 100% production failed Flying Probe. The reason was a wrong in circuit resistance. We compared OK device (DC2022) and NOK (DC2349…
Part Number: UCC28C43 Hi team,
The customer want to calculate switching frequency. Do you have any calculation to help? Due to the customer use 6.8nF capacitor and 2k resistor, the fig. 7-1 has little help to calculate the frequency. Could you help provide…
