APPLICATION INFORMATION
Resistor R
C
and capacitor C
C2
depend on the chosen inductance. For a 33-
μ
H inductor, the capacitance of C
C2
should be chosen to 33 nF, or in other words, if the inductor is
xx
μ
H, the chosen compensation capacitor should
be
xx
nF, the same number value. The value of the compensation resistor is then chosen based on the require-
ment to have a time constant of 0.3 ms for the R/C network of R
C
and C
C2
; hence for a 33-nF capacitor, a 10-k
resistor should be chosen for R
C
.
Capacitor C
C1
is depending on the ESR and capacitance value of the output capacitor, and on the value chosen
for R
C
. Its value is calculated using following equation:
COx ESRCOUT

RC
CC1
(7)
For a selected output capacitor of 22
μ
F with an ESR of 0.2
, and R
C
of 33 k
, the value of C
C1
is in the range of
100 pF.
