Component

Notes

> 25 V electrolytic capacitor, 100 µF or higher is suitable

> 25 V ceramic capacitor, 10 µF or higher is suitable

With COMP = 0, > 25 V electrolytic capacitor, 100 µF or higher is suitable

with COMP = 1, > 35 V ceramic capacitor, 22 µF (or 2 x 10 µF) or higher is

suitable

2.2 µF ceramic capacitor placed as close as possible to VUP pins. Higher

values allow lower DC-DC noise

From 100 nF to 220 nF ceramic capacitor. Higher values allow lower DC-DC

noise

C4, C6

220 nF ceramic capacitors

STPS130A or similar Schottky diode

1N4001-07, S1A-S1M, or any similar general purpose rectifier

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
