NCP3063 系列是广受欢迎的 MC33063 和 MC34063 单片 DC-DC 转换器的性能增强版。这些器件由内部温度补偿基准、比较器、带有源电流限制电路的受控占空比振荡器、驱动器和高输出电流开关组成。该控制器专门设计用于降压、升压或电压反相应用，且外部元件数量最少。NCP3063 降压评估板是一块最大开关频率为 250 kHz 的评估板，输出为 3.3V。输出能够承受 0.2 A 至 0.8 A 的负载，效率高于 73%（150 kHz 时）。3.3V 输出的输入电压为 7V 至 15V。特性和应用特性最大开关频率为 250 kHz 输入电压为 7V 至 15V 效率高于 73%（150 kHz 时）

The NCP3063 Series is a performance enhancement to the popular MC33063 and MC34063 monolithic DC-DC converters. These devices consist of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high output current switch. This controller was specifically designed to be incorporated in step-down, step-up, or voltage inverting applications with a minimum number of external components. The NCP3063 Buck Evaluation Board is a 250 kHz maximum switching frequency board with 3.3V output. The output is capable of loads from 0.2 A to 0.8 A with the efficiency higher than 73% (at 150 kHz). The input voltage for the 3.3V output is 7V to 15V.
