The Triac dimmer should be connected to the GCC960C102  power phase line L (see Figure 4). R1 is a fusible resistor used for short-circuit protection and transient current limitation during startup. D1~D4 are bridge rectifiers, with R3, C1, R2, L1 and their subsequent L2 and C3 at the input end forming an electromagnetic interference (EMI) filter. Diodes D5, D6, and capacitor C12 form a charge pump circuit. MOSFETs (T1 and T2) are half bridge power switches. The secondary windings L10A and L10B of inductor (choke) L10, as well as capacitors C14 and C15 connected in series to the filament, are used for filament preheating. The D50, D51, C52, C50, R51, and C51 connected to the filament below the right end of the CFL form the lamp current detection and feedback circuit. The position detection circuit of the dimmer potentiometer knob is composed of R40, R41, C40, C42, D40, D41, R43, and C41 connected between the output terminal of the bridge rectifier and the CS+pin of IC1 (UBA2014). R43 and C41 form the dimmer potentiometer knob position detection circuit. Compare the detection voltage on pin CS – of IC1 with the control voltage on pin CS+to control the half bridge frequency and adjust the lamp current, thereby achieving dimming.

After the system is powered on, the GCC960C102  bus voltage on capacitor C7 is charged to capacitor 31 through starting resistors R30 and R31. When the voltage on pin VDD of IC1 exceeds 13V, the oscillator begins to oscillate at the highest frequency fmax.
The fmax value is determined by the external capacitance C23 (100 pF) on pin CF of IC1 and the resistance R21 (33 k Ω) on pin IREF
