NCV890231 评估板提供了一种评估高频降压转换器设计的便捷方法。除了输入和使能电压的直流电源外，无需其他组件。可以使用外部时钟来同步开关频率；该板还提供同步输出，使其可以用作主控。它配置为 3.3 V 输出，开关频率为 2 MHz，最大输出电流为 2.0 A，典型汽车输入电压范围为 4.5 V 至 18 V。此外，由于开关频率折返，该板可调节高达 30 V 的电压。

The NCV890231 evaluation board provides a convenient way to evaluate a high-frequency buck converter design. No additional components are required, other than dc supplies for the input and enable voltages. An external clock can be used to synchronize the switching frequency; and the board also provides a synchronization output, enabling it to be used as a master. It is configured for a 3.3 V output with a 2 MHz switching frequency and a 2.0 A maximum output current, over the typical 4.5 V to 18 V automotive input voltage range. In addition, the board regulates up to 30 V thanks to switching frequency foldback.
