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 induc-
tance drop over temperature and load.
Output Capacitor Selection
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
energy while transitioning from full-load to no-load con-
ditions without tripping the overvoltage fault protection.
When using high-capacitance, low-ESR capacitors (see
the
Output-Capacitor Stability Considerations
section),
