We have questions about TPS61021A.
Question 1.
In datasheet p.16 Figure.14 "Startup waveform",
There are the place where the waveform of inductor current is large.
(Please check the attached document.)
Please tell us the reason why the waveform of inductor current is large.
Question 2.
We use TPS2553 on the input side of TPS61021A.
Curret limit of TPS2553 is 200mA.
Please tell us how much the maximum current is rising.
Are there any problems?
Best regards,
Takahiro Nishizawa
