Page 17: Working Theorem
AL512/513 Service Manual 7. WORKING THEOREM A. DC-DC CONVERTER This block provides adjustable output voltages of 9.2V, -6V, 18V and 3 to 4V for the panel. It consists of a Q114 transistor and power switch IC I108 (AIC 1526-1). When DC_ EN signal is high, then Q114 is activated and send one signal to activate I108. At this time I108 will send 200KHz 12V PWM to Q106, Which is connected with L111, Q106, D203 and C308, to boost 5V to 9.2V. -
