Notes
C1
> 25 V electrolytic capacitor, 100 µF or higher is suitable
or
> 25 V ceramic capacitor, 10 µF or higher is suitable
C2
With COMP = 0, > 25 V electrolytic capacitor, 100 µF or higher is suitable
or
with COMP = 1, > 35 V ceramic capacitor, 22 µF (or 2 x 10 µF) or higher is
suitable
C3
2.2 µF ceramic capacitor placed as close as possible to VUP pins. Higher
values allow lower DC-DC noise
C5
From 100 nF to 220 nF ceramic capacitor. Higher values allow lower DC-DC
noise
C4, C6
220 nF ceramic capacitors
D1
STPS130A or similar Schottky diode
D2
1N4001-07, S1A-S1M, or any similar general purpose rectifier
D3
BAT54, BAT43, 1N5818, or any low power Schottky diode with IF(AV) > 0.2
A, VRRM > 25 V, VF < 0.5 V. To be placed as close as possible to VOUT pin
