Maxim MAX20049双路降压转换器和双路LDO稳压器解决方案
Maxim公司的MAX20049是双路降压转换器和双路低压降(LDO)稳压器.双路降压转换器固定频率PWM工作,输入电压从5V到17V,而MAX20049C输入电压则从4V到17V.器件多所有的四个输出轨提供电压监测.当过压或欠压检测到,电源良好状态进入高阻抗.输出电压出厂时根据各种传感器图像需要设定为3.3V, 3.0V, 2.9V, 2.8V或 2.7V;串行化器和存储器的电源则为1.8V,1.2V,1.1V和小于1.0V.电压保护特性包括逐个周期的电流限制,带自动恢复的热关断,降压转换器工作在180°相差.它是业界ADAS应用中最小的PMIC.汽车AEC-Q100规范,主要用在照相机模块如环绕,后端和前端,以及点负载.本文介绍了MAX20049主要特性和优势,典型应用电路,以及评估板MAX20049 EVK主要特性和应用方案与电路图.
The MAX20049 is a dual step-down converter IC with two low-dropout regulators (LDOs), providing a single-chip solution for automotive cameras. The two step-down converters are designed for fixed-frequency PWM operation with input voltages from 5V to 17V for MAX20049 and 4V to 17V for MAX20049C. The dedicated high-voltage inputs allow for a flexible solution.
