Part Number:TPS7A8300
Hello,
When startup, we thought output voltage is rampup straightly like charging capacitor by constant current but the result isn't it.
The condition
Vout=1.2V
CSS/NR=160pF
Co=22uF+ 4.7uF x4
EN pin Low -> High
Is this phenomenon that startup circuit operation is changed around internal reference voltage because the slew rate is changed in 0.6 to 0.8V?
Why does this waveform happen? If there is any way to avoid this waveform, please let us know.
Best regards,
Toshihiro Watanabe
