ROHM芯片BD9211F的应用文档一、芯片各引脚基本功能：本芯片包含18个引脚，各个引脚功能及说明如下：图一IC内部结构图1、VCC：芯片供电。

电压范围：8V-18V；Vcc max=20V。

VCC引脚对地电容必须大于0.1uF，用于滤除噪声干扰。

2、STB：此引脚用于设置ON/OFF信号，当芯片关断时需要将其进行复位。

STB信号电压幅度需小于VCC电压幅度，若STB电压提前于VCC电压供给芯片，需要保证STB电压幅度小于4V。

原因如下图二所示：当VCC未建立，且STB电压建立时，若电压太大，会导致STB 与VCC间二极管导通，此时STB 电压会串到VCC电压上，导致芯片误动作。

图二STB引脚内部结构图STB引脚电压在0.8V和2V之间的状态为不定态，此电压有可能会使芯片误动作，因此要避免STB电压在这个区域间的状态。

3、GND：小信号地，尽可能的与PGND分开走。

这样可以保证在短的GND和PGND回路上有更少的干扰信号，GND信号尽量靠近连接插座。

4、RT：设定IC内部的充放电电流从而决定工作频率；改变RT引脚与地之间电阻的阻值，可以通过下图三公式设置基本驱动频率：图三基本驱动频率理论计算公式如：（①RT对地电阻33KΩ,基本频率为：178KHz；②RT对地电阻47KΩ,基本频率为：126KHz；③RT对地电阻51KΩ,基本频率为：116KHz；④RT对地电阻56KΩ,基本频率为：106KHz；）基本频率意思为N1、N2输出的频率仅由RT与GND之间的电阻决定。

频率会因为RT与FB之间的电阻Radj而改变。

下图四、图五中可以看出，改变FB与RT之间电阻RADJ的阻值可以调整频率范围。

当RADJ=100KΩ,∆Fout=84.46kHz.图四电阻Radj的取值与频率范围关系（Radj=100KΩ）图五FB电压范围与频率范围关系（Radj=100KΩ）RT与GND之间的电阻RRT决定基本频率。

基本频率是当FB=1.5V，在这个条件下运算频率调制范围且由RADJ决定。

User’s GuideROHM Solution Simulator3.5V to 40V Input, 1A Single 2.2MHz Buck DC/DC Converter for AutomotiveBD9P105EFV-C / Line ResponseThis circuit simulate the line response of BD9P105EFV-C. You can observe the fluctuation of the output voltage when the load current is abruptly changed. You can customize the parameters of the components shown in blue, such as VIN, IOUT, or peripheral components, and simulate the Line response with desired operating condition.General CautionsCaution 1: The values from the simulation results are not guaranteed. Please use these results as a guide for your design. Caution 2: These model characteristics are specifically at Ta=25°C. Thus, the simulation result with temperature variancesmay significantly differ from the result with the one done at actual application board (actual measurement).Caution 3: Please refer to the datasheet for details of the technical information.Caution 4: The characteristics may change depending on the actual board design and ROHM strongly recommend to doublecheck those characteristics with actual board where the chips will be mounted on.1 Simulation SchematicFigure 1. Simulation Schematic2 How to simulateThe simulation settings, such as simulation time or convergence options, are configurable from the ‘Simulation Settings’ shown in Figure 2, and Table 1 shows the default setup of the simulation.In case of simulation convergence issue, you can change advanced options to solve. Default statement in ‘Manual Options’ sets the time to start saving the result to 1.2ms. You can modify or delete it.Figure 2. Simulation Settings and execution3 Simulation Conditions3.1 How to define VIN voltage (VBAT initial voltage and VEN setting)The VBAT initial voltage and the VEN voltage are set in the ‘Manual Options’ text box for parameter setting consistency.The voltage level of VBAT initial and VEN, and the initial voltage of CBLK refer to the variable V_VBAT. To define the voltage level, s et V_VBAT value in ‘.param’ sentence in the text box from ‘Simulation Settings’ > ‘Advanced Options’ as shown in Figure 3.‘Simulation Settings’Figure 3. Definition of VIN voltage.In order to secure the simulation stability those three parameters should be the same. So do not change those parameters respectively.3.2 VBAT parameter setupFigure 4 shows how the VBAT parameters correspond to the VIN stimulus waveform.(b) Magnified viewFigure 4.VIN parameters and its waveforms VOUT VOUT VIN VIN4 BD9P105EFV-C_Tran modelTable 3 and Table 4 shows the model terminal function implemented. Note that BD9P105EFV-C_Tran is the behavior model for its load/line response operation, and no protection circuits or the functions not related to the purpose are not implemented.(Note 3) This model is not compatible with the external synchronization function.(Note 4) Use the simulation results only as a design guide and the data reported herein is not a guaranteed value.4.1 Parameter TSSBD9P105EFV-C_Tran model has the property ‘TSS’, which is the soft start time described in page 7 of the datasheet.The product has 3ms (typical) of the startup time of the output voltage. You can short cut the soft start by changing TSS value. The default TSS value is set to 0.2ms in this simulation and you can modify the value in the property editor.Figure 5.

ROHM开发出80V级高耐压DC/DC转换器“BD9G341AEFJ”【ROHM半导体（上海）有限公司10月27日上海讯】全球知名半导体制造商ROHM面向需要大功率（高电压×大电流）的通信基站和工业设备领域，开发出耐压高达80V的MOSFET 内置型DC/DC转换器“BD9G341AEFJ”。

“BD9G341AEFJ”采用功率系统工艺0.6µm的高耐压BiCDMOS，作为非绝缘型DC/DC 转换器，实现了80V的业界最高耐压水平，在ROHM的DC/DC转换器产品阵容中，也是耐压最高的产品。

利用ROHM擅长的模拟设计技术优势，在80V级的DC/DC转换器中，还实现了业界最高的转换效率。

与一般产品相比，本产品即使输出引脚发生意外短路（接触），也可通过保护电路抑制发热从而防止产品受损，因此还非常有助于提高应用产品的可靠性。

不仅如此，这些优势仅通过简单的小型8引脚封装即完全实现，可减少安装面积和周边零部件数量。

本产品于2015年10月开始以月产6万个的规模投入量产（样品价格 600日元/个：不含税）。

前期工序的生产基地为ROHM滨松株式会社（滨松市），后期工序的生产基地为ROHM Electronics Philippines, Inc.（菲律宾）。

今后，ROHM将充分发挥所擅长的模拟设计技术优势，继续开发高耐压、高效率、高可靠性的电源IC。

＜背景＞近年来，节能意识几乎在所有的领域持续高涨。

即使是在大功率工业设备类产品中，可支持大功率的功率元器件和电源IC节能型半导体的应用越来越广泛。

而当用于大功率产品时，为确保受到因雷电等导致的突发性浪涌电压时产品也不损坏，要求产品的耐压水平高于输入电压。

ROHM利用所擅长的最尖端的功率系统工艺和垂直统合型一条龙生产线，不仅可确保产品的特性，而且还面向非常重视可连续工作的可靠性和长期稳定供应的工业设备市场，开发出众多新产品。

此次，ROHM面向因智能手机的流量增加而需求日益扩大的通信基站和高性能化发展迅速的工厂FA设备、电机应用领域，开发出业界最高级别耐压的80V级DC/DC转换器。

ROHM芯片BD9211F的应用文档一、芯片各引脚基本功能：本芯片包含18个引脚，各个引脚功能及说明如下：图一IC内部结构图1、VCC：芯片供电。

电压范围：8V-18V；Vcc max=20V。

VCC引脚对地电容必须大于0.1uF，用于滤除噪声干扰。

2、STB：此引脚用于设置ON/OFF信号，当芯片关断时需要将其进行复位。

STB信号电压幅度需小于VCC电压幅度，若STB电压提前于VCC电压供给芯片，需要保证STB电压幅度小于4V。

原因如下图二所示：当VCC未建立，且STB电压建立时，若电压太大，会导致STB 与VCC间二极管导通，此时STB 电压会串到VCC电压上，导致芯片误动作。

图二STB引脚内部结构图STB引脚电压在0.8V和2V之间的状态为不定态，此电压有可能会使芯片误动作，因此要避免STB电压在这个区域间的状态。

3、GND：小信号地，尽可能的与PGND分开走。

这样可以保证在短的GND和PGND回路上有更少的干扰信号，GND信号尽量靠近连接插座。

4、RT：设定IC内部的充放电电流从而决定工作频率；改变RT引脚与地之间电阻的阻值，可以通过下图三公式设置基本驱动频率：图三基本驱动频率理论计算公式如：（①RT对地电阻33KΩ,基本频率为：178KHz；②RT对地电阻47KΩ,基本频率为：126KHz；③RT对地电阻51KΩ,基本频率为：116KHz；④RT对地电阻56KΩ,基本频率为：106KHz；）基本频率意思为N1、N2输出的频率仅由RT与GND之间的电阻决定。

频率会因为RT与FB之间的电阻Radj而改变。

下图四、图五中可以看出，改变FB与RT之间电阻RADJ的阻值可以调整频率范围。

当RADJ=100KΩ,∆Fout=84.46kHz.图四电阻Radj的取值与频率范围关系（Radj=100KΩ）图五FB电压范围与频率范围关系（Radj=100KΩ）RT与GND之间的电阻RRT决定基本频率。

基本频率是当FB=1.5V，在这个条件下运算频率调制范围且由RADJ决定。
