产品概要

 

背景

近年来，随着各种设备的电子化进程加速，电子元器件的安装数量也与日俱增，为了减少元器件的尺寸和数量，对于减少常被用来提高电路稳定性的电容器数量的要求增加。 因此，电源电路越来越需要即使电容器容量很小也能稳定工作的电源IC，但是，1μF以下的输出电容量很难确保应用产品所要求的稳定性。 为了解决这些课题，ROHM于2020年确立了用于电源IC的超稳定控制技术“Nano Cap?”。此次的新产品通过搭载Nano Cap?技术，实现了在输出电容器容量非常小的条件下也能稳定工作的LDO稳压器。

超稳定控制技术「Nano Cap」の要点
车载一次电源用LDO稳压器的工作稳定比较

新产品详情

“BD9xxN1系列”是车载一次LDO系列新产品，满足车载产品125℃以上工作和汽车电子产品可靠性标准“AEC-Q100”的要求，也满足一次电源输入电压40V以上等基本要求。利用新搭载的超稳定控制技术“Nano Cap?”，新产品能够支持不到普通产品1/10的100nF输出电容量，而且，即使在输入电压和负载电流波动时，也能实现应用产品要求的稳定性（输出电压波动在100mV以内：负载电流波动1mA?50mA/1?秒时）。围绕支持输出电容范围和响应性能，提供各项性能均衡的业界高性能产品。

应用示例

◇燃油喷射系统（FI）和胎压监测系统（TPMS）等动力总成系统
◇车身控制模块（BCM）等车身系统
◇仪表盘、平视显示器（HUD）等信息娱乐系统
除了车载一次电源应用之外，还适用于其他更广泛的应用领域。

支持工具

ROHM提供高精度SPICE模型“ROHM Real Model”，在新产品验证用的仿真模型中，利用ROHM自有的建模技术，忠实地再现了实际IC的电气特性和温度特性，可使仿真值与IC实物的值完全一致。通过可靠的验证，可有效防止实际试制后的返工等情况发生，有助于提高应用产品的开发效率。

参考设计 / 应用评估套件

 
    • Reference Design - REF66009
    • LogiCoA? Solution BUCK Converter (12V Input, 5V Output, 25W)

    • LogiCoA001-EVK-001 is a reference design for a BUCK converter that uses ROHM's analog-digital fusion control technology LogiCoA?, which includes a microcontroller ML62Q2035 suitable for LogiCoA?, a 100V gate driver BD2320EFJ-LA, LDO BD950N1WG-C, BD900N1WG-C, operational amplifier BU7481SG, and shunt resistor LTR100LJZPFSR020. Design data, sample software, and an operating system for power supply control are available for this reference design, as well as a reference board. We hope that you will have a chance to experience the analog-digital fusion control LogiCoA? and make use of it in your future power supply device development.

      Reference Program

      We offer a reference program comprising an OS for power control and firmware for BUCK converter control. Additionally, we provide a communication GUI that allows communication from a Windows PC. Please utilize these as design references. Reference Program and Communication GUI are available here.
