FP222GW has family look with FP202W and FP92W and the ID design is neat and clean and is welcomed by majority of users.
  • Page 49 #1 EMI Filter This circuit (fig. 2) is designed to inhibit electrical and magnetic interference for meeting FCC, VDE, VCCI standard requirements. Fig. 2 #2 Rectifier and filter AC Voltage (90-264V) is rectified and filtered by BD601, C605 (See Fig 3) and the DC Output voltage is 1.4*(AC input).
  • Page 50 Fig. 4 #4 Rectifier and filter D701 and C703 are to produce DC output. L701 is used to suppress high Frequency switching spikes. (See Fig.5) Fig. 5 #5 PWM Controller The PWM controller NCP1200A implements a standard current mode architecture. With an internal structure operating at a fixed 40KHz, the switch time is dictated by the peak current set-point.
  • Page 51 Fig. 6 #6 Feedback circuit PC123 is a photo-coupler and TL431 is a shunt regulation. They are used to detect the output voltage change and be the primary and secondary isolation. When output voltage changes, the feedback voltage will be compared and duty cycle will be decided to control the correct output voltage.
  • Page 52 The main parts of the control board are a push button, and a LED. (a) Push button: It’s a simple switch function, pressing it for “ON” to do the auto adjustment function, releasing it for “OFF” to do nothing. (c) LED: It indicates the DPMS status of this LCD monitor; green light means DPMS on (Normal operating condition).
  • Page 53 TL1451 is a dual PWM controller.C807 and R811 decide the working frequency.BLT_ADJ signal is from control board, control pulse width then decide how much energy delivery to CCFL also decide CCFL brightness. Q810 and Q811 be the buffer to rise the drive capability and the totem poles circuit can improve a capable of driving for Q812.C813 decide the striking time delay.
