Hello Sir:
We are using TPS63000.
But that device is abnormal when using 0.1uF of VINA.
Please refer our schematic and layout as below.
If our C227 is 0.1uF, please refer our measure waveform as below.
Ch1 VIN, Ch2 L1, Ch3 L2 and Ch4 is VOUT.
If our C227 is 10uF, please refer our measure waveform as below.
Ch1 VIN, Ch2 L1, Ch3 L2 and Ch4 is VOUT.
Please help to provide your recommendations for us and let us know how to fix this issue.
Thanks a lot.
