台湾飞特气动工具产品参数说明
尊敬的客户：
您好！
台湾飞特气动工具产品相关参数说明如下：
一、扭矩值
①FW-4SR-1为飞特冲击式气动扳手，正常拧紧螺丝的时间在5秒钟以内时，扭矩范围为8-16N.m。

超过5秒钟后扭矩值会加大。

②FW-4SRD-1、D-10为飞特冲击式气动起子，正常拧紧螺丝的时间在5秒钟以内时，扭矩范围为6-13N.m。

超过5秒钟后扭矩值会加大。

③FW-60SR-1为飞特双气缸油浴式气动扳手，正常拧紧螺丝的时间在5秒钟以内时，扭矩范围为14-26N.m。

超过5秒钟后扭矩值会加大。

④FW-60SRD-1、D-10为飞特双气缸油浴式气动起子，正常拧紧螺丝的时间在5秒钟以内时，扭矩范围为11-20N.m。

超过5秒钟后扭矩值会加大。

二、噪音值
在噪音测量方面，我们遵照ISO15744的标准，噪音值为85分贝，测量等级可增加3dB(A)用以消除生产和测量方法上的偏差。

绝大多数数值均依照Pneurop测试标准得出。

自2002年开始，针对声音测量的官方测试标准更改为ISO15744。

这两个标准之间的区别甚小，在多数情况下可以忽略不计。

在表述上，我们声明噪音级别低，我们是指与性价比不高的类似产品相比较。

在很多实际工位中，生产过程的噪音要远远高于工具无负载时的噪声，因此，通常建议操作者在使用时佩戴听力保护用具。

The internal compensation requires a minimum number of readily available standard external components.The SP1232F operates in the CC(Constant output Current) mode or CV(Constant output Voltage) mode, and the OCP current value is set by current sensing power resisters or setting non power resisters.The SP1232F is suitable for the DC/DC switching power applications when requested the current limit function. The devices are available in SOP-8L package and require very few external devices for operation.◆ DC/DC Converters with Current LimitTypical Application CircuitFigure1 Typical Application of SP1232F(High-accuracy Current Limit)Note1：1.RCS=120mV/I limit.,RCS is Power Resistors.2.RT=24000K/f osc ；Float frequency is 120KHz. 深圳芯派科技ＴＥＬ：１３５　３０４５　２６４６　（唐生）ＩＣＱ：２９４　４３４　３３６２ＩＣＱ：２９４　４３５　３３６２Figure2 Typical Application of SP1232F(Low-cost Current Limit) Note2：1.R3>25KΩ.R3 is Non Power Resistors.2.

The Constant output Current control Mode and Constant output Voltage control Mode.Over Current ProtectionThe SP1232F provides over current protection. A drop voltage on the current sensing resister is over the OCP value, the OCP function will shut down the controller. Soft StartThe SP1232F has internal soft start function to control rise rate of the output voltage and limits the large inrush current at start up. The typical soft start interval is about 3mS.Power on ResetA power-on reset circuit monitors the input voltage. When the input voltage exceeds 4.5V, the converter will start operation. Once input voltage falls below 4.3V, the controller will shut down.Over Temperature ProtectionThe SP1232F provides over temperature protection. The OTP will shut down the converter when junction temperatureexceeds160℃.Oncethejunctiontemperature cools down by approximately 40℃, the converter will resume normal operation. Current Limit ProtectionThe SP1232F provides two kinds of current limit Mode. When the SEN Pin series Power Resistors to the load. The current limit set according to the following equation:SENR 120mVit(A)CurrentLim =When the SEN Pin series Non Power Resistors to GND. The current limit set according to the following:Rsen 82K 100K Iout2.4A3.1AOscillator FrequencyThe SP1232F oscillator frequency is set by a single external resistor connected between the RT pin and the GND pin. The resistor should be located very close to the device and connected directly to the pins of the IC (RT and GND). The oscillator frequency rises when the resistor RT falls. To determine the timing resistance for a given switching frequency, use the equation below:TR 24000Kf(KHz)=Output Short-Circuit ProtectionThe SP1232F provides output short-circuit protection function. When V OUT is short (V FB <0.4V), the auto restart function can be started that restart the regulator cycle by cycle. The cycle time is set by internal counter.Figure 5 short-circuit protection timeAPPLICATION INFORMATIONOutput Voltage SettingFigure 6 Output Voltage SettingFigure 6 shows the connections for setting the output voltage. Select the proper ratio of the two feedback resistors R FB1 and R FB2 based on the output voltage. Typically, use R FB2>10kΩ and determine R FB1 from the following equation:OUT FB1FB2V R R 11.2⎛⎫=- ⎪⎝⎭Output Cable Resistance Compensation To compensate for resistive voltage drop across the charger's output cable, the SP1232F integrates a simple, user-programmable cable voltage drop compensation using the impedance at the FB pin. R FB1 is the high side resistor of voltage divider.[]FB1OUT FB2FB1OUT RV (1)1.02I .2R R 5⎡⎤=+⋅+⋅⋅⎢⎥⎣⎦Figure 7 12V in to 5V out Cable Compensation Inductor SelectionThe inductor maintains a continuous current to the output load. This inductor current has a ripple that is dependent on the inductance value: Higher inductance reduces the peak-to-peak ripple current. The tradeoff for high inductance value is the increase in inductor core size and series resistance, and the reduction in current handling capability. In general, select an inductance value L based on ripple current requirement:()OUT IN OUT IN OUTMAX RIPPLEV V V L V f I K SW ⨯-=Where V IN is the input voltage, V OUT is the output voltage, f SW is the switching frequency, I OUTMAX is the maximum output current, and K RIPPLE is the ripple factor. Typically, choose K RIPPLE =30% to correspond to the peak-to-peak ripple current being 30% of the maximum output current. With this inductor value, the peak inductor current is I OUT × (1+K RIPPLE /2). Make sure that this peak inductor current is less than the controller’s current limit. Finally, select the inductor core size so that it does not saturate at the peak inductor current. Input CapacitorThe input capacitor needs to be carefully selected to maintain sufficiently low ripple at the supply input of the converter. A low ESR capacitor is highly recommended. Since large current flows in and out of this capacitor during switching, its ESR also affects efficiency.The input capacitance needs to be higher than 100μF. The best choice is the ceramic type, however, low ESR tantalum or electrolytic types may also be used provided that the RMS ripple current rating is higher than 50% of the output current. The input capacitor should be placed close to the VIN and GND pins of the IC, with the shortest traces possible. In the case of tantalum or electrolytic types, they can be further away if a small parallel 1μF ceramic capacitor is placed right next to the IC. Especially C2 capacitor should be placed as close as possible to the VIN pin.Output CapacitorThe output capacitor also needs to have low ESR to keep low output voltage ripple. The output ripple voltage is:INRIPPLE OUT RIPPLE ESR 2OUTV V I K R 28f LC SW =+⨯Where I OUTMAX is the maximum output current, K RIPPLE is the ripple factor, R ESR is the ESR of the output capacitor, f SW is the switching frequency, L is the inductor value, and C OUT is the output capacitance. In the case of ceramic output capacitors, R ESR is very small and does not contribute to the ripple. Therefore, a lower capacitance value can be used for ceramic type. In the case of tantalum or electrolytic capacitors, the ripple is dominated by R ESR multiplied by the ripple current. In that case, the output capacitor is chosen to have sufficiently low ESR. For ceramic output capacitor, typically choose a capacitance of about 470μF.For tantalum or electrolytic capacitors, choose a capacitor with less than 50mΩ ESR.PCB Layout Recommendations1. PCB trance defined as SW node, which connects to the inductor, should be as short and wide as possible.2. Inductance between the SW terminal and the output VOUT as far as possible with the ground wire to reduce the output side of the switch coupling.3. ALL sensitive analog traces such as SEN and FB should place away from high-voltage switching nodes SW nodes to avoid coupling.4. Input bypass capacitor should be placed to the IN pin as close as possible.5. Feedback resistor should be placed to the FB pin as close as possible.6. Gather the ground terminals of the V IN capacitor(s), V OUT capacitor(s), and the source of the low-side MOSFETs as close as possible. Signal ground and power ground should be connected strongly together near the device.7. The ground of input capacitance and output capacitance should be placed as close as possible.Package Information （Units:mm ）SP1232FWide Input Range CC/CV Synchronous Buck Regulator Restrictions on Product Use◆Si-Power is continually working to improve the quality and reliability of its products.
