说明

MAX1973/MAX1974评估板(EV kit)是一块完全安装和测试、包含两个独立电路的电路板,分别用来评估MAX1973和MAX1974。这两个电路都工作于2.6至5.5V的输入电压。MAX1973电路输出(OUT1)为2.5V或1.8V预置电压可选,或加入外置反馈电阻,在1.25V至VIN之间调节输出。MAX1974电路输出(OUT2)为1.5V或1V预置电压可选,或加入外置反馈电阻,在0.75V至VIN之间调节输出。每路输出都具有1A的电流能力。MAX1973电路还具有跳线器选择的电源上下限功能,允许输出电压升高或降低4%,而MAX1974电路具有电源就绪(POK)输出,指示稳压器输出电压是否在调节范围内。
