说明

MAX1993评估板(EV kit)演示MAX1993器件标准的4A应用电路。该DC-DC变换器降压转换高电池电压或交流适配器的电压,为芯片组、DRAM供电或其它低压电源产生一个精确的低电压电源。

MAX1993评估板从7V至24V的电池电压输入,产生动态可调的1.0V/1.5V输出电压。输出高达4A的电流,且效率超过90%。该评估板工作于300kHz开关频率,且具有出色的线路和负载瞬态响应。

该评估板是一块完全安装和测试过的电路板。通过改变电阻R6、R7和R8,还能够评估0.7V至5.5V范围内的其它动态可调输出电压。

该评估板也可评估1.8V/2.5V预置输出电压的MAX1992。
