I have a buck converter.
Vin = 12V
Vout = 5V
Iload = 0.5A
I have one dropout requirement. The input voltage will drop from 12V
to 4V
for 10s
. Including ramp up/down time of 10ms
. During this time, my 5V
output should be stable.
Q: How to calculate the value for my input/output reservoir capacitors value so that I have constant 5V
during dropout time. Is there any formula?
