随着数字技术的发展,数字控制稳压电源得到了广泛的应用。图1是用五端功率集成稳压器W200C 组成的数字控制集成稳压电源。数字控制端D_1～D_(?)为八位二进制代码,通过它控制三极管V_1～V_(?)(3DG6D×8)有选择地导通与截止,从而起到调整输出电压的作用。R_SCP 为限流电阻,
With the development of digital technology, digital control of regulated power has been widely used. Figure 1 is a five-terminal power regulator W200C integrated digital control integrated power supply. Digital control terminal D_1 ~ D_ (?) Is an 8-bit binary code, through which the control transistor V_1 ~ V _ (?) (3DG6D × 8) selectively turn on and off, which play a role in regulating the output voltage. R_SCP current limiting resistor,
