LT1611
Transient Response
The inverting architecture of the LT1611 can generate a
very low ripple output voltage. Recently available high
value ceramic capacitors can be used successfully in
LT1611 designs with the addition of a phase lead capaci-
tor, C
PL
(see Figure 7). Connected in parallel with feedback
resistor R1, this capacitor reduces both output perturba-
OPERATIOU
tions due to load steps and output ripple voltage to very
low levels. To illustrate, Figure 7 shows an LT1611 invert-
ing converter with resistor loads R
L1
and R
L2
.
R
L1
is
connected across the output, while R
L2
is switched in
externally via a pulse generator. Output voltage wave-
forms are pictured in subsequent figures, illustrating the
performance of output capacitor type and the effect of C
PL
connected across R1.
