3.逻辑板5V和3.3V供电电压产生电路PFC端输出的电压分成三路:第一路送到副电源板,用以产生32V的调谐电压和12V的伴音功放电压;第二路PFC电压经F8003后,加到Q8016的漏极;第三路PFC电压经F8003、T8005的初级绕组加到IC8023的①
3. Logic board 5V and 3.3V supply voltage generation circuit PFC end of the output voltage is divided into three: the first one to the secondary power supply board to generate a tuning voltage of 32V and 12V audio amplifier voltage; the second PFC voltage by F8003, added to the Q8016’s drain; the third PFC voltage by the F8003, T8005 primary winding added to the IC8023 ①
