NCP3170 是一款灵活的同步 PWM 开关降压稳压器。NCP3170 的工作电压范围为 4.5 V 至 18 V，最大输出电流为 3 A，能够产生低至 0.8 V 的输出电压。NCP3170 还集成了电流模式控制。为了减少外部元件数量，内部设置了许多功能，包括软启动、电源良好检测和开关频率。NCP3170 目前采用 SOIC-8 封装。

The NCP3170 is a flexible synchronous PWM Switching Buck Regulator. The NCP3170 operates from 4.5 V to 18 V, sourcing up to 3 A and is capable of producing output voltages as low as 0.8 V. The NCP3170 also incorporates current mode control. To reduce the number of external components, a number of features are internally set including soft start, power good detection, and switching frequency. The NCP3170 is currently available in an SOIC-8 package.
