This data was taken with the components listed below mounted on the printed circuit board shown in Figure 23.
For high efficiency and small circuit board size, the Sanyo Os--Con capacitors are recommended for C8, C9, C10
and C11.
C8, C9, C10 = Sanyo Os--Con #6SA330M, 330 mF 6.3 V.
C11 = Sanyo Os--Con #10SA220M, 220 mF 10 V.
L1 = Coilcraft S5088--A, 5.0 mH, 0.11 Ω.
