We have questions about input capacitor of TPS54328.
In datasheet p.13 8.2.2.3 Input Capacitor Selection,
TI recommends a ceramic capacitor over 10 µF for the decoupling capacitor.
Question 1.
Please tell us the reason why you recommend over 10μF.
Question 2.
Can we use the capacitor lower than 10μF?
Please tell us the minimum capacitance and the reason if we can use lower than 10μF.
Question 3.
What happens to the IC if we use the capacitor lower than 10μF.
Best regards,
