9a. This configuration constantly monitors the inductor
current, allowing accurate current-limit protection.
Alternatively, high-power applications that do not
require highly accurate current-limit protection may
reduce the overall power dissipation by connecting a
series RC circuit across the inductor (Figure 9b) with an
equivalent time constant:
where R L is the inductor’s series DC resistance. In this
configuration, the current-sense resistance equals the
inductor’s DC resistance (R SENSE = R L ). Use the worst-
case inductance and R L values provided by the induc-
tor manufacturer, adding some margin for the
inductance drop over temperature and load.
Output Capacitor Selection
L
R L
= C EQ × R EQ
The output filter capacitor must have low enough equiv-
alent series resistance (ESR) to meet output ripple and
load-transient requirements, yet have high enough ESR
to satisfy stability requirements. The output capaci-
tance must be high enough to absorb the inductor
