ADP2389/ADP2390评估板是一款完整的12 A、18 V降压稳压器解决方案，用户可采用近乎理想的印刷电路板(PCB)布局来评估ADP2389/ADP2390的性能。

通过可编程限流功能，输出电流可对电感进行优化。 峰值限流阈值预设为21 A以确保12 A输出电流能力。

开关频率可在200 kHz至2.2 MHz范围内进行编程，从而实现可堆叠多相功率解决方案。

增强瞬态响应特性可提高负载瞬态电流性能，并降低输出电容。

ADP2389/ADP2390评估板输出预设为1.8 V，且开关频率设置为500 kHz。 不同的输出电压设置可以通过选用合适的无源器件来实现。 环境工作温度范围为−40°C至+85°C。
