ripple(pp)
Nominal operating input voltage.
Desired output voltage.
Desired output current.
Desired peaktopeak inductor ripple current. For maximum output current it is suggested that I
L
be chosen to be less
than 10% of the average inductor current I
L(avg)
. This will help prevent I
pk (Switch)
from reaching the current limit
threshold set by R
SC
. If the design goal is to use a minimum inductance value, let I
L
= 2(I
L(avg)
). This will
proportionally reduce converter output current capability.
Maximum output switch frequency.
Desired peaktopeak output ripple voltage. For best performance the ripple voltage should be kept to a low value
since it will directly affect line and load regulation. Capacitor C
O
should be a low equivalent series resistance (ESR)
electrolytic designed for switching regulator applications.
The following Converter Characteristics must be chosen:
