At normal temperature, we have adjusted our TI products.
The appendix is part of our detailed application of TI products, and I hope to help confirm whether there are any hidden dangers and areas we need to pay attention to.
At the same time, there are also some technical problems, I hope TI can help analyze.
1, TPS62410:
Phenomenon: when we have MODE = 0, the waveform appears in the annex, and there is an underexcitation phenomenon. After adjusting MODE = 1, the output is relatively stable.
Question: is the phenomenon at MODE = 0 normal? Is there any other place that needs attention and attention when adjusted to MODE = 1?
2, TPS622314:
The same as TPS62410
3, TPS22918:
Phenomenon: according to the calculation method proposed by SPEC, we calculate the suitable CT value (470pF, 680pF, 1uF), and adjust the value of CT, which will change the time of Delay.
But the output voltage rise time is different when measured by real machine.
Question: will the capacitance of CT affect the Tr of the later stage voltage rise? What are the specific reasons?
At the present stage, we have begun the verification of high and low temperature, and please help to investigate and analyze the above problems.
