说明

MAX1830评估板(EV kit)从3V至5.5V的输入电源电压产生1.8V的电压输出。以94%的效率输出高达3A电流。MAX1830评估板包含一个MAX1830降压开关稳压器,稳压器内置同步整流器来提高效率和减少外部组件的数目。可利用电阻设置的、固定关断时间、电流模式结构允许针对负载和线路瞬变优化。按该评估板的配置在3.3V输入的情况下工作于约550kHz的频率,在5V的输入情况下工作于约770kHz的频率。

MAX1830评估板可配置为输出一个预定为1.5V、1.8V和2.5V的输出电压,或是利用反馈调节输出一个范围在1.1V到输入电压间的电压。

该评估板也可以用于评估预置输出电压为1.5V、2.5V和3.3V的MAX1831器件,也能在1.1V到输入电压间调节输出电压。
