LT8637 42V, 5A Synchronous Step-Down Silent Switch
1Rev. 0DESCRIPTIONLT863742V, 5A Synchronous Step-Down Silent Switcherwith 2.5μA Quiescent CurrentDemonstration circuit 3020A is a 42V, 5A (7A Peak) syn-chronous step-down Silent Switcher ® with spread spec-trum frequency modulation featuring the L T ®8637. The demo board is designed for 5V output from a 5.8V to 42V input. The wide input range allows a variety of input sources, such as automotive batteries and industrial sup-plies. The LT8637 is a compact, low emission, high effi-ciency, and high frequency synchronous monolithic step-down switching regulator . The LT8637 is the same as the LT8636, except it has a VC pin for external compensation. This allows the customer to optimize the loop response, or to parallel multiple regulators for higher current appli-cations. The proprietary Silent Switcher architecture mini-mizes electromagnetic emissions with simplified filter and reduced layout sensitivity. Selectable spread spectrum mode further improves EMI performance, making it per-fect solution to the noise sensitive applications. The regu-lator’s ultralow 2.5μA quiescent current–with the output in full regulation–enables applications requiring highest efficiency at very light load currents, such as automotive and battery powered portable instruments.Peak current mode control with minimum on-time of as small as 30ns allows high step-down conversion even at high frequency. The LT8637 switching frequency can be programmed either via oscillator resistor or external clockAll registered trademarks and trademarks are the property of their respective owners.PERFORMANCE SUMMARYover a 200kHz to 3MHz range. The default frequency of demo circuit 3020A is 2MHz.The SYNC/MODE pin on the demo board DC3020A is grounded (JP1 at BURST position) by default for low ripple Burst Mode ® operation. To synchronize to an external clock, move the Jump JP1 to SYNC/FCM and apply the external clock to the SYNC terminal ON THE 3020A. In sync mode, the part runs in forced continuous mode. Without external clock applied, the SYNC/MODE pin is floating, and the part runs in forced continuous mode. This mode offers fast transient response and full frequency operation over a wide load range. Alternatively, move the Jump JP1 to the SPREAD-SPECTRUM, and the SYNC/MODE is tied to INTVCC, the part runs in forced continuous mode with spread spectrum function enabled. The LT8637 data sheet gives a complete description of the part, operation and application information. The data sheet must be read in conjunction with this demo manual for demo circuit 3020A. The layout recommendations for low EMI operation and best thermal performance are available in the data sheet section Low EMI PCB Layout and Thermal Considerations and Peak Output Current. Contact ADI applications engineer for support.Design files for this circuit board are available .Specifications are at T A = 25°CSYMBOL PARAMETERCONDITIONSMIN TYPMAX UNITSV IN_EMI Input Supply Range with EMI Filter 5.842V V OUT Output Voltage4.855 5.15V I OUT Maximum Output Current Derating is Necessary for Certain V IN and Thermal Conditions 5Af SW Switching Frequency 1.852 2.15MHz EFFEfficiencyV IN = 12V, I OUT = 3A94.4%QUICK START PROCEDUREDemonstration circuit 3020A is easy to set up to evalu-ate the performance of the LT8637. Refer to Figure 1 for proper measurement equipment setup and follow the procedure below:NOTE: When measuring the input or output voltage ripple, care must be taken to avoid a long ground lead on the oscilloscope probe. Measure the output voltage ripple by touching the probe tip directly across the output capacitor.1. Make sure the Jump JP1 is on the BURST position. Refer to the schematic.2. With power off, connect the DC power supply to VEMI and GND. Connect the load from VOUT to GND.3. Connect the voltage meter across the VIN_SENSE and GND for V IN measurement, and VOUT_SENSE and GND for V OUT measurement.4. Turn on the power at the input.NOTE: Make sure that the input voltage does not exceed 42V.5. Check for the proper output voltage (V OUT = 5V). NOTE: If there is no output, temporarily disconnect theload to make sure that the load is not set too high or is shorted.6. Once the proper output voltage is established, adjust the load within the operating ranges and observe the output voltage regulation, ripple voltage, efficiency and other parameters. For efficiency measurement, use the VIN_SENSE, GND, and VOUT_SENSE, GND accordingly.7. An external clock can be added to the SYNC terminal when SYNC function is used (JP1 on the SYNC position). When JP1 is in SYNC, and no external clock is connected to the SYNC terminal of the board, the SYNC/FCM pin is floating, and the LT8637 runs in forced continuous mode. JP1 can also set LT8637 in spread spectrum mode (JP1 on the SPREAD-SPECTRUM position).Figure 1. Proper Measurement Equipment Setup2Rev. 0QUICK START PROCEDUREEfficiency, 12V IN, FCMFigure 2.

士林SS系列变频器说明书-V2_38
说明书导读士林电机SS系列变频器,为符合市面上大部分的应用层面需求,设计了许多复杂的参数功能,对于初次接触变频器的客户,可能会造成使用上的困扰,因此我们希望读者能够仔细阅读说明书的每一部分,以便充分掌握此变频器的使用方法。
在阅读说明书时,有不明之处,欢迎来电询问。
说明书的第2章详细列出了士林SS系列变频器的规格,2-5节指导客户安装变频器,并且强调使用变频器时应注意的安全事项。
第3章指导客户如何使用变频器,3-1节列出了变频器的操作模式;3-2节说明如何使用操作器;3-3节列出了简单的操作步骤。
第4章对参数作了详细的解释说明。
以下是本说明书的专有名词定义:1. 变频器输出电流的频率,称为「输出频率」。
使用者设定的频率(可使用操作器、多段速选择、电压信号、电流信号,通信设定),称为「目标频率」。
电机启动后,变频器的输出频率会逐渐加速至目标频率,然后在目标频率下稳定运转,此时的输出频率称为「稳定输出频率」。
2. 变频器的参数设定,在第4章中有详细的说明。
当使用者对参数设定不熟悉时,任意地调整参数设定值,往往导致变频器无法正常运作。
参数Pr998,可回复所有参数为默认值,此参数的操作流程,请参考第4 章Pr998。
3. 变频器的使用说明分为两大模式,「变频器的操作模式(简称操作模式)」与「操作器的工作模式(简称工作模式)」。
变频器的操作模式,决定运转频率的参考来源与电机启动信号的来源。
士林变频器共有九种操作模式,详细说明请参考3-1节。
操作器主要负责监视数值、参数设定与运转频率设定,士林操作器共有三种工作模式。
详细说明请参考3-2节。
4.「端子名称」与「功能名称」的差别:在变频器控制板端子台的附近和主回路板端子台的附近,有打印上去的文字,用以区分各端子,它被称为「端子名称」。
对于「控制端子」与「多功能输出端子」,除了它的端子名称外,仍必须定义它的「功能名称」,功能名称所指的是该端子实际的作用。
在解释各端子的功能时,所使用的名称皆为「功能名称」。

Typical values are the average values expected in large quantities and are provided for information purposes only. These values can and do vary in different applications. All operating parameters should be validated by user’s technical experts for each application.Application and Handling Instructions▪Please provide for static discharge protection during handling. As long as the hybrid driver is not completely assembled, the input terminals have to be short-circuited. Persons working with devices have to wear a grounded bracelet. Any synthetic floor coverings must not be statically chargeable. Even during transportation the input terminals have to be short-circuited using, for example, conductive rubber. Worktables have to be grounded. The same safety requirements apply to MOSFET- and IGBT-modules.▪Any parasitic inductances within the DC-link have to be minimised. Over-voltages may be absorbed by C- or RCD-snubber networks between main terminals for PLUS and MINUS of the power module.▪When first operating a newly developed circuit, SEMIKRON recommends to apply low collector voltage and load current in the beginning and to increase these values gradually, observing the turn-off behaviour of the free-wheeling diode and the turn-off voltage spikes generated across the IGBT. An oscillographic control will be necessary. Additionally, the case temperature of the module has to be monitored. When the circuit works correctly under rated operation conditions, short-circuit testing may be done, starting again with low collector voltage.▪It is important to feed any errors back to the control circuit and to switch off the device immediately in failure events.Repeated turn-on of the IGBT into a short circuit with a high frequency may destroy the device.▪The inputs of the hybrid driver are sensitive to over-voltage. Voltages higher than V S +0,3V or below -0,3V may destroy these inputs. Therefore, control signal over-voltages exceeding the above values have to be avoided.▪The connecting leads between hybrid driver and the power module should be as short as possible (max. 20cm), the driver leads should be twisted.Further application supportLatest information is available at . For design support please read the SEMIKRON Application Manual Power Modules available at .General DescriptionThe Board 93 GB SKYPER® 42 is an adaptor board for the IGBT module SKiM® 93 (spring contact). The board is paralleling three channels so the SKiM module can be used in half bridge configuration. The board can be customized allowing adaptation and optimization to the used IGBT module.The switching characteristic of the IGBT can be influenced through user settings, e.g. changing turn-on and turn-off speed by variation of R Gon and R Goff. Furthermore, it is possible to adjust the monitoring level and blanking time for the DSCP (see Technical Explanations SKYPER® 42 R).Please note:This technical explanation is based on the Technical Explanations for SKYPER®42 R.
