Hi Tony,
Overall is good to me. It is better to change inductor to 1uH and COUT47uF to 22uF. This can help to have more suitable LC corner frequency for bettter loop stabilty. Because i see the there is a EC=220uF.
Thanks,
Colin
Please help to check whether the Layout is correct.
TPS62140ARGTR chip circuit input 6v, the output voltage is normal; But the 7v output voltage has been falling, I do not know whether it is the chip itself
Hi Tony,
Could you test VIN, SW and Vout in normal and abnormal condition?
It would promote me to better debug, thanks!
Colin
