ROHM芯片BD9211F的中文应用文档

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 AutomotiveBD9P105MUF-C / Load ResponseThis circuit simulate the load response of BD9P105MUF-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 load 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.The default statement “.tran 0 2.4m 0.4m” in ‘Manual Options’ sets the simulation execution options. By default, run for t=2.4ms and save the waveforms after t=0.4ms. You can modify or delete it.Refer to Section 3 about the sentence “.param V_VBAT=12”.Figure 2. Simulation Settings and executionSimulation Settings Simulate3. Simulation Conditions3.1 How to define VIN voltage (VBAT and VEN setting)The VBAT and VEN voltages are set in the ‘Manual Options’ text box for parameter setting consistency. The voltage level of VBAT and VEN, and the initial voltage of CBLK refer to the variable V_VBAT. To define the voltage level, set the 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 IOUT parameter setupFigure 4 shows how the IOUT parameters correspond to the IOUT stimulus waveform.(b) Magnified viewFigure 4. IOUT parameters and its waveforms IOUT VOUT IOUT VOUT VIN4. BD9P105MUF-C_Tran modelTable 3 and Table 4 shows the model terminal function implemented. Note that BD9P105MUF-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 TSSBD9P105MUF-C_Tran model has the property ‘TSS’, which is the soft start time describ ed 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 TO-247封装绝缘垫片热阻注意事项说明书

ROHM TO-247封装绝缘垫片热阻注意事项说明书

Application Note热设计关于绝缘垫片的热阻的注意点对于TO (Transistor Outlines)封装等,在背面有用于散热的裸漏金属焊盘(散热焊盘)的封装形式,当将这种非绝缘型的封装安装在散热片上时,会经由封装的金属焊盘对散热片施加高压,因此需要使用绝缘垫片进行隔离。

在进行热估算时,如果绝缘垫片的热阻取值不恰当,会无法得到正确的热估算结果,因此本应用手册记载了关于绝缘垫片的热阻的注意点。

图1是TO封装之一的TO-247封装的外观图。

在背面有用于散热的裸漏金属焊盘,如果是MOSFET产品,该焊盘和封装内部的芯片(半导体芯片)的漏极存在电气连接,因此在电路应用中会存在高压。

当将此封装安装在散热片上时,如图2所示,需要在封装和散热片之间插入绝缘型的散热垫片。

在散热片和TO封装之间,通常会使用螺丝或者夹片等固定件进行加压使两者牢固接触。

加压时的压力会造成绝缘垫片产生压缩并使其热阻发生变化。

热阻发生变化的原因,包括压力所导致的接触热阻变化等。

获取绝缘垫片的热阻在查看绝缘垫片的产品目录和官网的公开规格时,会发现不同厂家的描述不一样,有的厂家的产品规格里包含了接触热阻、有的没有包含接触热阻,也有的将压力作为参数进行了记载等。

即便是对于包含了接触热阻的规格值,也需要考虑接触热阻随垫片两端的接触材质和表面粗糙度所产生的变化。

有的产品在规格里只记载了导热系数。

导热系数是物质固有的参数,用来表示物质内部发生热转移的难易程度,与产品的厚度无关,同时因为无法判断接触热阻,有可能造成热估算偏小。

因此,需要从垫片厂商获取与实际使用的压力值所匹配的热阻数据来进行热估算。

图3是低硬度的绝缘垫片、图4是高硬度的绝缘垫片的示例。

低硬度的绝缘垫片会在施加压力时变薄,因此垫片自身的热阻会变低。

高硬度的绝缘垫片在施加压力时厚度几乎不变,但是热阻也会变低,这是因为当施加压力时,接触热阻会变低。

对于高硬度的绝缘垫片,接触热阻会在垫片两端的接触材质和表面粗糙度变化时可能变大,因此更容易受到压力的影响。

ROHM芯片BD9211F的中文应用文档

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。

For the BD9G101G, the below inductors are recommended within the 4.7μH to 15μH range. Recommended Inductor Murata DEM4518C Series TAIYO YUDEN LSXND6060WKL Series(2) Input CapacitorTo reduce input ripple voltage, please connect a low ESR ceramic capacitor near the VCC pin. For the BD9G101G, we recommend a capacitance less than 4.7μF. And in the event an electrolytic capacitor is used, mount a 1μF ceramic capacitor in parallel to prevent oscillation.(3) Output CapacitorTo reduce output ripple, a low ESR ceramic capacitor is recommended. And in addition to taking into account DC bias characteristics, please provide sufficient margin with respect to the absolute maximum rated output voltage.Vpp =∆IL ×12π×f ×Co+∆IL ×R ESR [V]Please design in a way that it is held within Capacity Ripple Voltage. In the BD9G101G, it is recommended a ceramic capacitor over 10μF.(4) Output voltage settingThe internal reference voltage of the ERROR AMP is 0.75V. The output voltage is determined from the following formula.VOUT =R1+R2R2×0.75 [V]light loads, please ensure that the sum R1+R2 for the output resistance satisfies the following formula.R1+R2≤VOUT ×103Example output resistance settings: 5V output voltage → R1=3.9kΩ, R2=0.68kΩ 12V output voltage → R1=7.5kΩ, R2=0.51kΩOutput Voltage Setting ΔI LInductor Current(5) Feed-forward capacitor CSPPlease mount feed-forward capacitor in parallel to output resistance R1.In order that a feed-forward capacitor may adjust the loop characteristic by adding the pair of a pole and zero to the loop characteristic. A phase margin is improved and transient response speed improves.The feed-forward capacitor CSP should use the value near the following formulasCSP=4.7kR1×0.15 [μF]Example CSP settings: 5V output voltage → R1=3.9kΩ, R2=0.68kΩ, C SP=0.1μF or 0.22μF12V output voltage → R1=7.5kΩ, R2=0.51kΩ, C SP=0.1μFTo prevent BSTUVLO operation during reduced power and light loads, we recommend connecting a feed-forward capacitor CSP in parallel with the output resister R1. The feed-forward capacitor improves phase margin and transient response by adding a zero-pole pair to the loop characteristics. This works to limit output fluctuation. For the feed-forward capacitor CSP, use an output resistance value near to the following formula.Through the above measures, BSTUVLO will not activate under light loads and VIN-VOUT<3V.(6)Bootstrap CapacitorTo prevent malfunction of the boot pin’s internal circuit, connect a CBS T=15000pF ceramic capacitor between the BST and LX pins.(7)Catch DiodeSelect a Schottky barrier diode that meets withstand voltage and rated current requirements.●Evaluation Board Layout GuidelinesPCB layout is a critical portion of good power supply design. Some paths that conduct fast current / voltage change may cause noises and degrade the power supplying performance due to leakage flux or interaction with parasitic capacitance.To help reducing these problems, the VCC pin should be bypassed to ground with a low ESR ceramic capacitor. Also, the large current is generated especially on the following 2 loops; Bypass input capacitor -> Inductor -> Output capacitor or Catch diode -> Inductor -> Output capacitor. Therefore, the distance between the output capacitor and the catch diode, or the distance between the output capacitor and the bypass input capacitor on the GND pattern should be as short as possible.The input bypass capacitor, the catch diode and the inductor should be located as close to the IC as possible. Please keep GND line on the top layer to avoid GND level fluctuation caused by external connection.●Evaluation Board BOMBelow is a table showing the bill of materials.

measurement of semiconductors. Table 1 summarizes the specifications of these two types of thermocouples. Although Type T has a small tolerance, its positive electrode has a high thermal conductivity. Therefore, the thermocouple may serve as a heat sink, decreasing the measured temperature below the actual temperature. Thus, it is considered that thermocouples of Class 1 Type K are ideal for the thermal measurement.
The third point is regarding tip treatment of thermocouples. The simplest method is to twist the tip several times to make it a twisted wire as shown in Figure 2. Nevertheless, since the temperature is measured at the first contact point in this method, the remaining section is unnecessary and may cause undesirable heat radiation. However, since cutting off the remaining section compromises the contact, the temperature becomes unstable.

我这里将这些品名表示法贴出来,方便大家查阅。

今天先贴ROHM电阻的。

先举个例子吧:MCR01MZPJ102,这是0402封装的1K的电阻,精度是5%。

MCR01就表示0402封装;MZP表示的是盘料的规格是每盘10000片;J表示精度5%;102自然是表示阻值了,规则自然大家都清楚,10是有效数字,2是0的个数,连起来就是1000,单位欧姆,即1Kohm。

如果有小数点用R表示。

如果是0hom则用000表示。
