External Component Selection
accuracy, LED ripple current, switching frequency and component size.
NOTE:
Table 4. EXTERNAL COMPONENT SELECTION
Table 5. INDUCTOR SELECTION DEPENDING ON VBAT SUPPLY VOLTAGE
Table 4 provides the recommended external components L and C2 that offer the best performance relative to the LED current
LED Current (mA)
Larger C2 capacitor values allow to reduce further the LED ripple current if needed.
