Service Manual Electronic Circuit Theory 2.1 Inverter PWM circuit 2.1.1)Inverter Control circuit:(fig.2) Fig.2 ON/OFF voltage signal coming from IF BD will enable U1 to work.C2 is used to dump noise. During the striking period, if the voltage at VSEN_POL(pin12) reaches a threshold of approximately 2.85V, the transformer output voltage will be regulated until the striking timer expires.
Page 10
Service Manual pin VSEN_POL(pin12) is greater than approximately 1.5V, the PWM dimming polarity will be negative. A voltage range of approximately 0.1V to greater than 1.5V to PDIM(pin11) results in minimum and maximum brightness respectively. The striking and operating frequency is determined by the external resistor (R16) and capacitor( C1) connected to Pin8(CT).

Service Manual Fig.3 The transformer (T1 to T12) secondary winding leakage inductance and output capacitances that are in the inverter PCB board, forms a lower pass filter, which converts the square-wave driving signal into a sinusoidal output voltage signal for CCFL.

Service Manual As shown in Fig.7, peak-current-mode control is utilized for Flyback PWM. The U850 (SG6901A) inserts a synchronized 0.5V ramp at the beginning of each switching cycle. When the IPWM voltage, across the sense resistor, reaches the threshold voltage, 0.65V or 0.7A selected by RANGE, the OPWM will be turned off after a small propagation delay Tpd-pwm.
