NCP3063 系列是流行的 MC34063A 和 MC33063A 单片 DC-DC 转换器的高频升级版。这些器件由内部温度补偿参考、比较器、带有源电流限制电路的受控占空比振荡器、驱动器和高电流输出开关组成。该系列专门设计用于降压、升压和电压反相应用，且外部元件数量最少。特性和应用特性工作至 40 V 输入低待机电流输出开关电流至 1.5 A 输出电压可调频率工作至 150 kHz 电池充电器电池充电器应用大功率 LED 照明

The NCP3063 Series is a higher frequency upgrade to the popular MC34063A and MC33063A monolithic DC-DC converters. These devices consist of an internal temperature compensated reference, comparator, a controlled duty cycle oscillator with an active current limit circuit, a driver and a high current output switch. This series was specifically designed to be incorporated in Step-Down, Step-Up and Voltage-Inverting applications with a minimum number of external components.
