Notes:
1. The output current has I
LEDPK
ripple. To reduce ripple current, use a large electrolytic capacitor in
parallel with the LED. Ensure the capacitor voltage rating is high enough to withstand an open-LED
condition or use a Zener diode for protection.
2. The output power is not equal to the apparent power due to the slight phase shift between the output
voltage and current.
