Hi Yingjiao,
I don't see an issue with the schematic and inductor.
Please take some measurements on the VIN and VOUT of the TLV62569 device at start-up to see probably some overvoltage or strange behavior.
Best regards, Sepp
Part Number: TLV62569 Tool/software: Hi,
Our design maximum height is 1.4mm.
We found SOT235 package maximum is 1.45mm, but we meansure sample on hard all about ~1.1mm.
May I know why this tolerance is big?(and it seem same SOT23 package with DDCR? but…
Part Number: TLV62569 Tool/software: Hi team,
I have a issue about noise as below, the noise would impact MCU work that the most severe damage the MCU.
How could I improve the 3.3V noise?
Part Number: TLV62569 Tool/software: After PCBA returned, it was found that the main IC was unstable, which was found to be caused by the power supply (3.3V).
