Application Design Example for an Offline (115 Vac) Buck Application:
In addition to traditional DC−DC applications, the NCL30100 can also be used in offline applications, a schematic and PCB
layout are provided to illustrate a typical circuit configuration.
• Input voltage: V
in
− 115 Vac
• Nominal LED current: 700 mA (rms)
• LED
ripple
: 120 mA (peak−to−peak)
• V
LED
: 3.2 V
• Freewheel diode V
f
: 0.5 V
• Target Switching Frequency: 50 kHz
Dimming using PWM signal 1 kHz with duty cycle 0 – 99%
In this application example, there is schematic and PCB only. The design steps are the same as above mentioned.
