bridge rectifier D1, D3, D4 and D6. To limit current peaks
generated during on time period, capacitor C1 is used. CX1,
C2 and L1 are an EMI filter to protect mains against current
spikes mainly generated by D2 if Q1 is turned on. The
NCL30100 is powered through resistors R1 and R2. The
Vcc voltage is limited by D7. Maximum LED current is set

by resistors R3, R4 and R5. In this case Rsense is 0.33 W to
reach higher accuracy. A small capacitor C3 is used to filter
out spikes which are generated during the turn off of diode
D2. It is recommended to use L2 with low series resistance
since current is flowing through the inductor continuously
and D2 should be selected for low forward voltage drop and
fast reverse recovery time.
