2.集成电路稳压电源黑白电视机的集成稳压电源大都采用KC582C,其典型应用电路如图3所示。把图3的电路与图2比较,两电路的二次保险BX_2之前的降压,整流、滤波电路是完全相同的。区别主要在稳压电路。集成稳压电源也属于串联型稳压电源。图3中的BG为电源调整管,推动放大电路和取样比较电路均 2. Integrated circuit power supply Black and white TV’s integrated power supply most of the KC582C, the typical application circuit shown in Figure 3. The circuit in Figure 3 compared with Figure 2, the two circuits before the insurance BX_2 buck, rectifier, filter circuit is exactly the same. The main difference in the regulator circuit. Integrated power supply is also a series of regulated power supply. BG in Figure 3 for the power adjustment tube to promote the amplifier circuit and sample comparison circuit
