概述

说明

MAX20010C/MAX20010D为高效率、同步、降压型转换器，工作在3.0V至5.5V输入电压范围，提供0.5V至1.5875V输出电压范围。宽输入/输出电压范围以及高达6A的负载驱动能力，是板载负载点和后端稳压应用的理想选择。IC在整个负载、电源和温度范围内的输出精度达到±2%。MAX20010D提供改进的瞬态响应。

IC可以工作在2.2MHz固定频率PWM模式，提供更好的抗噪性和负载瞬态响应；也可工作在脉冲频率调制模式(SKIP)，提高轻载状态下的工作高效。2.2MHz工作频率允许使用全陶瓷电容，使方案的占位面积最小化。可编程扩频调制最大程度抑制电磁辐射。相对于分立式方案，集成的低RDS(ON)开关大大提高重负载时的效率，并简化电路布局。

IC具有工厂预设输出电压(选项信息请参见定购信息)。I2C接口提供动态电压调节，摆率可编程。其他特性包括可编程软启动、过流和过热保护。
