单片机用超薄开关稳压电源

Ultrathin Switching Mode Power Supply Used Single chip Microcomputer

提出了一种便于应用者携带的单片机用超薄、高性能开关稳压电源，详细论述了其工作原理，并给出了电路图，指出了减少噪声的两种方法，并且这种稳压电源的价格仅是市场上同类产品的２／３．

The paper proposes a switching mode power supply with ultrathin and high performance used single chip mirocomputer, which is convenient for users to carry with. A detail discussion of its opration principle and its circuit diagram are given and two ways of reducing noise indicated. Besides, the price for this mode voltage stabilizer is only two thirds of that for similar ones in the market.
