LM78M12中⽂资料LM341/LM78MXX Series3-Terminal Positive Voltage RegulatorsGeneral DescriptionThe LM341and LM78MXX series of three-terminal positive voltage regulators employ built-in current limiting,thermal shutdown,and safe-operating area protection which makes them virtually immune to damage from output overloads.With adequate heatsinking,they can deliver in excess of 0.5A output current.Typical applications would include local (on-card)regulators which can eliminate the noise and de-graded performance associated with single-point regulation.Featuresn Output current in excess

fixed voltage regulator series has built-in thermal overload protection which prevents the de-vice from being damaged due to excessive junction tem-perature.The regulators also contain internal short-circuit protection which limits the maximum output current,and safe-area pro-tection for the pass transistor which reduces the short-circuit current as the voltage across the pass transistor is in-creased.Although the internal power dissipation is automatically lim-ited,the maximum junction temperature of the device must be kept below +125?C in order to meet data sheet specifica-tions.An adequate heatsink should be provided to assure this limit is not exceeded under worst-case operating condi-tions (maximum input voltage and load current)if reliable performance is to be obtained).1.0Heatsink ConsiderationsWhen an integrated circuit operates with appreciable cur-rent,its junction temperature is elevated.It is important to quantify its thermal limits in order to achieve acceptable per-formance and reliability.This limit is determined by summing the individual parts consisting of a series of temperature rises from the semiconductor junction to the operating envi-ronment.A one-dimension steady-state model of conduction heat transfer is demonstrated in The heat generated at thedevice junction flows through the die to the die attach pad,through the lead frame to the surrounding case material,to the printed circuit board,and eventually to the ambient envi-ronment.Below is a list of variables that may affect the ther-mal resistance and in turn the need for a heatsink.R θJC (Component Variables)R θCA (Application Variables)Leadframe Size &Material Mounting Pad Size,Material,&LocationNo.of Conduction Pins Placement of Mounting Pad Die SizePCB Size

regulators have internal thermal shutdown to protect the device from over-heating.Under all possible operating conditions,the junction temperature of the LM78MXX/LM341XX must be within the range of 0?C to 125?C.A heatsink may be required depending on the maxi-mum power dissipation and maximum ambient temperature of the application.To determine if a heatsink is needed,the power dissipated by the regulator,P D ,must be calculated:I IN =I L +I GP D =(V IN ?V OUT )I L +V IN I Gshows the voltages and currents which are present in the circuit.The next parameter which must be calculated is the maxi-mum allowable temperature rise,T R (max):θJA =TR (max)/P D If the maximum allowable value for θJA ?C/w is found to be ≥60?C/W for TO-220package or ≥92?C/W for TO-252pack-age,no heatsink is needed since the package alone will dis-sipate enough heat to satisfy these requirements.If the cal-culated value for θJA fall below these limits,a heatsink is required.As a design aid,Table 1shows the value of the θJA of TO-252for different heatsink area.The copper patterns that we used to measure these θJA are shown at the end of the Application Note Section.reflects the same test results as what are in

功能描述
MT7612是一款自适应高压线性恒流LE D驱动芯 片， 采用美芯晟自主专利技术的平均电流控制和补 偿方案， 只需要极少的外围器件就可以达到在较宽 母线电压范围内优异的恒流特性。MT7612 所提供 的四种工作模式可以根据系统对效率和PF的要求 来选择，有效地降低了系统成本。 启动过程 在市电开关开启后，V DD 通过一个连接到母线的 启动电阻充电。当 V DD 达到 9V 时，启动控制逻 辑进入正常工作。当 V DD 继续升高达到 15V 时， 内部钳位电路起作用， VDD 电压稳定在 15V。当 母线掉电后，V DD 开始下降到 7.5V 后，开启欠压 阈值设置，关断整个系统，如图 1 所示。 线电压补偿 传统线性恒流架构，当母线电压升高，LE D 灯串 导通的宽度越大， 平均输出电流也会随之增大。 为 了保持输出电流的恒定， MT7612 采用了线电压补 偿技术，通过分压电阻串检测母线电压 VS F 的电 压， 来实现芯片内部线电压补偿， 从而使得芯片保 持恒流输出。 驱动控制 随着母线电压的正弦波变化升高到一定值， 系统自 动开启 LE D 灯串。对于模式 1~ 模式 3，工作在自 适应线性驱动模式， 其开启时间由系统自动调节达 到恒流输出。 对于模式 4，工作在线性驱动模式，即当母线电压 高于 LE D 电压后即保持 LE D 导通， 直至母线电压 低于 LE D 导通压降，则 LE D 电流截止。

In such a case, it is recommended to reduce the power dissipation by inserting the power limiting resistor R SD in the input terminal, and to reduce the junction temperature as a result.V INV The power dissipation P D of IC is expressed in the following equation.P D = (V IN '-V OUT )I OUT + V IN 'I BIf V IN ' is reduced below the lowest voltage necessary for the IC, the parasitic oscillation will be caused according to circumstances.In determining the resistance value of R SD , design with margin should be made by making reference to the following equation.V IN - V IN 'R SD <I OUT + IB(4) Connect the input terminal and GND, and the output terminal and GND, by capacitor respectively.The capacitances should be determined experimentally because they depend on printed patterns. In particular, adequate investigation should be made so that there is no problem even at time of high or low temperature.(5) Installation of IC for power supplyFor obtaining high reliability on the heat sink design of the regulator IC, it is generally required to derate more than 20% of maximum junction temperature (T j MAX.) Further, full consideration should be given to the installation of IC to the heat sink.(6) IEC (International Electronical Commission)-65 Specification.(a) IEC (International Electronical Commission)-65 is the standard, parts testing method, machinery and tolls (used in connecting main power directly and indirectly) Which are used at home and general building. The purpose of the above standard is not to breaking out the risk which is related to an electric shock, a heating, a fire and the damage of surrounding parts in the case of normal or abnormal operating.

7812主要参数有:输出直流电压U0＝＋12V，输出电流L：0.1A,M：0。
5A，电压调整率10mV/V，输出电阻R0＝0。
15Ω，输入电压UI的范围15～17V .因为一般UI要比U0大3～5V ，才能保证集成稳压器工作在线性区.图1 三端稳压器7812引脚图及外形图图2 是用三端式稳压器W7812构成的单电源电压输出串联型稳压电源的实验电路图。
其中整流部分采用了由四个二极管组成的桥式整流器成品(也叫整流堆,型号为2W06）,当然也可以自已用四个速流二极管（如,IN4001）组成。
滤波电容C1、C2一般选取几百~几千微法。
当稳压器距离整流滤波电路比较远时，在输入端必须接入电容器C3（数值为0.33μF ），以抵消线路的电感效应，防止产生自激振荡。
输出端电容C4（0。
1μF)用以滤除输出端的高频信号,改善电路的暂态响应。

Power and Operation4.1 Power SelectionThe CPT213B Capacitive Sense Evaluation Board is designed to be powered by two different sources:•Through the on-board USB.•Through the EXP header.The figure shows how the different power sources are connected to the device.Figure 4.1. CPT213B SLEXP8019A Power SupplyWhen the USB is connected, the board is powered from the LDO internal to the USB device, which is in turn powered by the USB cable.The board can also be powered externally through the VMCU and GND pins of the expansion header when the board is attached to a power supply or an EFM MCU Starter Kit.When power is provided through the USB or an external power supply, the device can act as a stand alone device. When it is connec-ted to an EFM MCU Starter Kit through the expansion header, the device acts as a peripheral to the MCU by providing capacitive sense capabilities.4.2 StandaloneIn standalone mode, the CPT213B SLEXP8019A on the CPT213B Capacitive Sense Evaluation Board is designed to showcase and test the board's features or act as a breakout board for any application. To operate in this mode, apply power using the USB connector or an external supply.The board can operate on its own to demonstrate and test the board's touch features and functionalities. The CPT213B SLEXP8019A features configurable options such as touch characteristics, output characteristics, and user feedback peripherals. The device's fea-tures can be configured in Simplicity Studio using [Xpress Configurator ], and the capacitive sense data can be viewed in the [Capaci-tive Sense Profiler ].The touch qualification engine on the device will process the touch information and output the results through I2C. The device outputs can be accessed through the expansion header, and the capacitive sense inputs can be accessed through the vias on the board.No tR e co mme nd edn s4.3 Connected to the Expansion HeaderThe CPT213B Capacitive Sense Evaluation Board is designed to quickly attach to any EFM32 and EFM8 MCU starter kit and jump-start the development of capacitive sense capable applications.

PeripheralsThe starter kit has a set of peripherals that showcase some of the features of the CPT213B device.Be aware that some CPT213B I/O routed to peripherals are also routed to the breakout pads. This must be taken into consideration when using the breakout pads for your application.5.1 Capacitive Sense Touch PadsThe kit has 13 capacitive sense touch pads. The touch pads are connected in order to pins CS00 - CS12 of the CPT213B SLEXP8019A. After the touch pad inputs have been processed by the touch qualification engine, the CPT213B SLEXP8019A will out-put the result through I2C.The capacitive sense inputs can be configured for different thresholds, debounce counter values, scan periods, gain, scanning meth-ods, touch time-outs, and touch exclusiveness using the [Xpress Configurator ] in Simplicity Studio. The device outputs can also be configured for different pin polarities and drive strength.See the CPT213B SLEXP8019A Data Sheet for more detailed information on the different configurations.CPT213B DeviceFigure 5.1.

启动过程
上电时，VCC 通过一个连接到输入母线的启动电 阻（Rst1 和 Rst2）充电。当 VCC 达到 12V 时， 控制逻辑就开始工作，内部开关开始开关动作。如 果 VCC 升高到 15.5V，则被钳位。如果 VCC 低于 5.5V，则 MT7812B 将被关闭。

其中 L 为电感的感量；ILPK 是流过电感的电流峰值； VIN 是输入端整流桥整流后的输入直流电压；VLED 是负载 LED 上的正向压降。 当 CS 引脚上的电压达到设定的 400mV 峰值限制， 内部开关管将被关断，SOURCE 端电压升高，功 率 MOS 管也被关断，电感将通过续流二极管对负 载 LED 放电，直到电感电流下降到零时，芯片将 再次开启内部开关管。功率管的关断时间为：

2）管脚 5,6 为高压 MOS 管的漏极（Drain），是最 大的噪声源。在芯片的底部要铺地线将漏极与 其余管脚进行隔离。参考下面的示意图。
3）VOVP 的走线及对应电阻的端头要远离 MOS 管的漏极（Drain，即管脚 5,6）。走线要尽量短。

MT7812B 设 置 了 系 统 的 最 大 截 止 时 间 为 TOFF_MAX=400uS ， 最 小 截 止 时 间 为 TOFF_MIN=1.5uS。由 TOFF 的计算公式可知，如果电 感量很大，TOFF 可能会超过 TOFF_MAX，使电感电流 还没有降到零又开始下一个周期充电，如果连续五 次以上出现 TOFF_MAX，系统就会进入打嗝-重启状 态；反之，如果电感量很小，TOFF 可能会小于 TOFF_MIN，使电感电流出现为零的时刻，电感电流 进入断续模式，所以实际的负载 LED 电流小于目 标设计值。因此需要选择合适的电感值。美芯晟科 技有限公司提供本芯片的设计软件，方便客户选取 合适的工作频率及电感值。
