说明

MAX20074评估板演示MAX20074的性能和行为,该器件属于MAX20015–MAX20018/MAX20073/MAX20074家族引脚兼容、低电压、降压型开关调节器IC。

输出电压为0.5V至3.8V时,调节器提供高达3A电流。器件工作在2.7V至5.5V输入电源电压,是后端调节和负载点应用的理想选择。在整个负载、电源和温度范围内的总误差为1.5%。基本开关频率为2.2MHz,允许使用全陶瓷电容设计。调节器可同步至外部时钟或者置于节省功耗的跳脉冲模式,以提高轻载效率。

调节器提供使能输入和故障指示输出。可使用外部分压器和内部0.5V电压基准设置输出电压;也可由工厂设置为特定输出电压,无需使用昂贵的0.1%精度电阻即可达到1.5%输出精度。软启动时间和故障保持时间也可由工厂设置。

调节器包括过热关断和过流限制。器件可持续工作在-40°C至+125°C环境温度范围。
