引言自从美国TI 公司推出通用可编程 DSP 芯片以来,DSP 技术得到了突飞猛进的发展,但 DSP 的电源设计始终是 DSP 应用系统设计的一个重要的组成部分, TI 公司的DSP 家族一般要求有独立的内核电源和 IO 电源,由于DSP 在系统中要承担大量的实时数据计算、因为在 其CPU 内部,部件的频率开关转换会使系统功耗大大增加,所以,降低 DSP 内部CPU 供电电压无疑是降低系统功耗最有效的方法之一 [1]。

如TMS320F2812 DSP 的核电压为,IO 电压为;因此,传统的线性稳压器(如 78XX 系列)已经不能满足要求,面对这些要求,TI 公司推出了一些双路低压差电源调整器, 的双路低压差(且其中一路还可调)电压调整器,非常适合于 基于此,本文对该电源芯片进行了详细的介绍,并设计了基于 DSP 的电源电路。

BX-301M ID R ANGE M EMBRANEI NSTRUCTIONSMet One Instruments, Inc.1600 NW Washington Blvd.Grants Pass, Oregon 97526Telephone 541-471-7111Facsimile 541-471-71161 About the BX-301 Mid-Range MembraneThe BX-301 is a special purpose mid-range membrane foil assembly which may be used to verify the linearity of the BAM-1020 mass calculation system. The mass calculation of the BAM-1020 is inherently linear in nature, and therefore it is unnecessary to audit a mid range point in the vast majority of applications. The BX-301 is provided only as a convenience to certain customers who may be required to perform the check by local regulations.The BAM-1020 unit performs a span membrane check automatically every hour using it’s built-in membrane with a mass of approximately 0.800 mg/cm2. The BX-301 allows the user to periodically perform an additional span check at about 0.500 mg/cm2.The BX-301 membrane is a fragile assembly, and must be handled very carefully. Any puncture or damage to the foil surface will render the part useless. Any dirt or contamination on the foil surface will be measured as mass, and will also invalidate the measurement. This assembly must be protected and stored in a safe location away from heat and direct sunlight.2 Mid Range Span Check ProcedureNote: The BAM-1020 unit must be powered on and warmed up for at least one hour before performing the test. The pump does not need to be running during warm-up.1. Remove the ten case cover screws and washers from the BAM-1020. You will needto access the inside of the unit later to complete the test.2. Verify the factory determined ABS value of the BAM-1020 unit. This can be found inthe SETUP > CALIBRATE menu or on the calibration certificate for the unit. This is the expected mass of the span membrane foil in the unit, and will be about 0.800mg/cm2.3. Enter the TEST > CALIBRATE menu on the user interface. This is the screen thatwill be used for the membrane tests. See Section 7.13 of the BAM-1020 manual.The CALIBRATE Test Screen4. Press the START soft key to start a membrane measurement with the existing foil.The test will take about eight minutes to complete. The unit will then display themeasured value of the span membrane foil as the CAL MASS M value. Comparethis value with the ABS (expected) value and record the results. These shouldtypically match within a few micrograms. Note: If these values disagree by 5% ormore, then there is something wrong with the unit such as a dirty membrane or an incorrect ABS value. Do not proceed with the test if the BAM-1020 is not reading its own membrane correctly.5. Remove the BAM case cover. Locate the membrane assembly on the inside of theunit, and the brass raceway in which the membrane assembly slides forwards and backwards. Remove the small dust cover (two small screws and washers). Set the parts aside.MembraneMotorDust CoverMembraneAssemblyMembraneControl ArmThe Membrane Assembly Inside the BAM-10206. Carefully remove the existing membrane from the unit: Pull back the control armagainst it’s spring pressure until you can slide the membrane from the back of the assembly. There should be an expected mass value printed on the back of the mid-range membrane. Record this value. Insert the mid-range membrane foil exactly as the other membrane was installed. Note: Make sure the pin of the membrane is in the slot of the control arm, or the test will not work. Swapping membranes is a very simple matter once you know what you are doing.7. Press the START soft-key to start the test with the mid-range membrane in place.When the unit has calculated and displayed the new CAL MASS M value, record it and start the test over. Perform the test two more times and take an average of the three measured values. This average must be within 5% of the expected valueprinted on the membrane, and will typically be within a few micrograms. Record the results.8. Remove the mid-range membrane and replace the original part.

以下资料涵盖了SUS301从退火状态到全硬的材质的主要机械性能。

不过,如果可能的话,让你们公司的钢材供应商提供相关资料更准确。

让第三方检测实验室、材料研究室提供材料性能报告,也是一个很好的措施--只是很多公司不愿这个投资。

从自己的经验里来看,结合以下资料和其硬度,可以很好的得出比较准确的结果。

测硬度就简单了,一般的公司应该都有。

The strain-hardened austenite is at least partially transformed to ma rtensite by this work. Despite the high strengths achieved there is still enough residual ductility to enable severe cold deformation. Although non-magnetic in the annealed condition, when cold worked the grade becomes strongly attracted to a magnet.WeldingGood characteristics suited to all standard methods. Grade 308L filler rod is re commended. Welds in Grade 301 must be annealed for maximum corrosion resistance; this is not necessary in 301L or 301LN. Welding and post weld annealing will bo th remove high strength induced by prior cold rolling.Spot welding is commonly used to assemble cold rolled 301 components. The very s mall heat affected zone associated with this rapid welding technique results in little reduction of overall component strength.ApplicationsTypical applications include:·Rail car structural components - often roll formed, brake pressed or stretc h formed to profiles but also used flat.·Airframe sections·Highway trailer components·Automotive wheel covers·Wiper blade holders and clips·Toaster springs·Stove element clips·Screen frames·Curtain walls。

With a +5V power supply, the PS301/PS302/PS303 guarantee <60Ω ON-resistance. ON-resistance matching between channels is within 2Ω. ON-resistance flatness is less than 6Ω over the specified range. All three devices guarantee low leakage currents (<100pA @ 25oC, <10nA @ +85oC) and fast switching speeds (tON < 150ns). Break-before-make switching action protects against momentary crosstalk (PS303).
Note 1: Signals on NC, NO, COM, or IN exceeding V+ or GND are clamped by internal diodes. Limit forward diode current to 30mA maximum.
Caution: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied.

Description
The PS301/PS302/PS303 are improved high precision, medium voltage analog switches designed to operate with single power supplies. The PS301 is a single-pole single-throw (SPST), normally open (NO) switch. The PS302 has the same pinout as the PS301 but is a normally closed (NC) switch. The PS303 has one normally open (NO) and one normally closed (NC) switch per package. Each switch conducts current equally well in either direction when on. In the off state each switch blocks voltages up to the power-supply rail.
