技术问答

如今电动汽车行业发展迅猛，科技感在电动汽车的身上体现的淋漓尽致，为了给客户提供更极致的体验，车内座舱越来越智能，屏幕越来越大。因此车载中控屏的需求日益增多，在车载中控屏中需要给主控制器提供一个稳定的电压，这里推荐使用ROHM的LDO芯片BD3571YFP-ME2给主控芯片供电。下图是车载中控屏的系统框图：

图1：载中控屏系统框图

ROHM的LDO BD3571YFP-ME2应用于车载中控屏中具有以下优势：
1、该LDO能承受50V高电压，适用于汽车的车载中控屏系统。
2、静态电流低至30μA，能有效减小整个系统的损耗。
3、在输出电流为200mA时，输出电压精度±2%，能给系统提供更加稳定的电压。
4、LDO短路保护的设计采用折叠式，可以减少故障时的热量，适用于汽车的工作温度。

【应用】ROHM为您提供LDO的输出电流容量增加的绝佳解决方案：并行连接LDO

本应用笔记是ROHM提供的一些关于如何并行连接LDO的说明。想增加LDO的输出电流容量时，或者当单个LDO的功耗不足时，如果需要使用两个LDO来分散耗散，则并行连接LDO可以解决。

【经验】LDO线性稳压器的并联之使用二极管并联LDO

本文是ROHM“LDO线性稳压器的并联”系列文章中的一篇，讲述如何使用二极管并联LDO。在使用二极管进行LDO并联的方法中，由于输出路径中有二极管，因此输出电压会下降二极管VF的量，因此需要采取在LDO的输出电压设置中添加VF部分等相应的对策。

【经验】LDO线性稳压器的并联之使用镇流电阻并联LDO的方法

本文是ROHM系列文章“LDO线性稳压器的并联”中的一篇，介绍使用镇流电阻并联LDO的方法。使用镇流电阻并联LDO的方法中，输出电流可按计算公式求出的值分配。由于LDO的输出电流会流过镇流电阻，因此在负载点会产生电压降，电阻中会产生功率损耗。
