The output capacitor maintains the output voltage and supplies
the HPLED current when the LX switch is on. It also stabilizes

stability for the two-LED and one-LED cases is shown in Figure 31
and Figure 32, respectively. Choose a capacitor with a capacitance
greater than the minimum shown in Figure 31 and Figure 32
for the worst-case dc bias voltage and temperature condition.

L = 2.2 μH + 20% for Two-LED Designs
Note that dc bias characterization data is available from
capacitor manufacturers and should be taken into account
when selecting input and output capacitors. 16 V capacitors are
recommended for most two-LED designs. Designs with 1 mm
height restrictions can also use 0603 case size, 16 V capacitors
in parallel.
