Actual minimum input voltage to maintain a regulated output will depend upon output voltage and load current. See Applications Information.Note 4: An internal power-on reset (POR) latch is set on the positive transition of the SHDN pin through its threshold. The output of the latch activates current sources on each SS pin which typically sink 1.5mA, discharging the SS capacitor. The latch is reset when both SS pins are driven below the soft-start POR threshold or the SHDN pin is taken below its threshold.Note 5: To enhance dropout operation, the output switch will be turned off for the minimum off time only when the voltage across the boost capacitor drops below the minimum boost for 100% duty cycle threshold.The ● denotes the specifi cations which apply over the full operatingtemperature range, otherwise specifi cations are at T J = 25°C. V VIN1/2 = 15V, V BST1/2 = open, V RT/SYNC = 2V, V VOUT1/2 = open, unless otherwise specifi ed.This indicates that the output is overloaded and current is pulled from the SS pin, reducing the regulation point. FB1/FB2 (Pins 17, 14): The FB pin is the negative input to the error amplifi er. The output switches regulate this pin to 0.8V, with respect to the exposed ground pad. Bias current fl ows out of the FB pin.SHDN (Pin 15): The shutdown pin is used to turn off both channels and control circuitry to reduce quiescent current to a typical value of 9µA. The accurate 1.28V threshold and input current hysteresis can be used as an undervoltage lockout, preventing the regulator from operating until the input voltage has reached a predetermined level. Force the SHDN pin above its threshold or let it fl oat for normal operation.R T/SYNC (Pin 16): This R T/SYNC pin provides two modes of setting the constant switch frequency. Connecting a resistor from the R T/SYNC pin to ground will set the R T/SYNC pin to a typical value of 0.975V. The resultant switching frequency will be set by the resistor value. The minimum value of 15.4k and maximum value of 133k sets the switching frequency to 1.5MHz and 250kHz respectively.Driving the R T/SYNC pin with an external clock signal will synchronize the switch to the applied frequency. Synchro-nization occurs on the rising edge of the clock signal after the clock signal is detected, with switch 1 in phase with the synchronization signal. Each rising clock edge initiates an oscillator ramp reset. A gain control loop servos the oscillator charging current to maintain a constant oscillator amplitude. Hence, the slope compensation and channel phase relationship remain unchanged. If the clock signal is removed, the oscillator reverts to resistor mode and reapplies the 0.975V bias to the R T/SYNC pin after the synchronization detection circuitry times out. The clock source impedance should be set such that the current out of the R T/SYNC pin in resistor mode generates a frequency roughly equivalent to the synchronization frequency. BST1/BST2 (Pins 20, 11): The BST pin provides a higher than V IN base drive to the power NPN to ensure a low switch drop. A comparator to V IN imposes a minimum off time on the SW pin if the BST pin voltage drops too low. Forcing a SW off time allows the boost capacitor to recharge.Exposed Pad (Pin 21): GND. The Exposed Pad GND pin is the only ground connection for the device. The Exposed Pad should be soldered to a large copper area to reduce thermal resistance. The GND pin is common to both chan-nels and also serves as small-signal ground. For ideal operation all small-signal ground paths should connect to the GND pin at a single point, avoiding any high current ground returns.PIN FUNCTIONS83501fbwill be generated at the incoming frequency on the rising edge of the synchronization pulse with switch 1 in phase with the synchronization signal. In addition, the internal slope compensation will be automatically adjusted to pre-vent subharmonic oscillation during synchronization. The two regulators are constant frequency, current mode step-down converters. Current mode regulators are con-trolled by an internal clock and two feedback loops that control the duty cycle of the power switch. In addition to the normal error amplifi er, there is a current sense amplifi er that monitors switch current on a cycle-by-cycle basis. This technique means that the error amplifi er commands current to be delivered to the output rather than voltage.A voltage fed system will have low phase shift up to the resonant frequency of the inductor and output capacitor, then an abrupt 180°, shift will occur. The current fed sys-tem will have 90° phase shift at a much lower frequency, but will not have the additional 90° shift until well beyond the LC resonant frequency. This makes it much easier to frequency compensate the feedback loop and also gives much quicker transient response.The Block Diagram in Figure 1 shows only one of the switching regulators whose operation will be discussed below. The additional regulator will operate in a similar manner with the exception that its clock will be 180° out of phase with the other regulator.When, during power up, the POR signal sets the soft-start latch, both SS pins will be discharged to ground to ensure proper start-up operation. When the SS pin voltage drops below 80mV, the V C pin is driven low disabling switching and the soft-start latch is reset. Once the latch is reset the soft-start capacitor starts to charge with a typical value of 3.25µA.As the voltage rises above 80mV on the SS pin, the V C pin will be driven high by the error amplifi er. When the volt-age on the V C pin exceeds 0.7V, the clock set-pulse sets the driver fl ip-fl op which turns on the internal power NPN switch. This causes current from V IN, through the NPN switch, inductor and internal sense resistor, to increase. When the voltage drop across the internal sense resistor exceeds a predetermined level set by the voltage on the V C pin, the fl ip-fl op is reset and the internal NPN switch is turned off. Once the switch is turned off the inductor will drive the voltage at the SW pin low until the external Schottky diode starts to conduct, decreasing the current in the inductor. The cycle is repeated with the start of each clock cycle. However, if the internal sense resistor voltage exceeds the predetermined level at the start of a clock cycle, the fl ip-fl op will not be set resulting in a further decrease in inductor current. Since the output current is controlled by the V C voltage, output regulation is achieved by the error amplifi er continually adjusting the V C pin voltage.The error amplifi er is a transconductance amplifi er that compares the FB voltage to the lowest voltage present at either the SS pin or an internal 0.8V reference. Compensa-tion of the loop is easily achieved with a simple capacitor or series resistor/capacitor from the V C pin to ground. Since the SS pin is driven by a constant current source, a single capacitor on the soft-start pin will generate controlled linear ramp on the output voltage.If the current demanded by the output exceeds the maxi-mum current dictated by the V C pin clamp, the SS pin will be discharged, lowering the regulation point until the output voltage can be supported by the maximum current. When overload is removed, the output will soft-start from the overload regulation point.V IN1 undervoltage detection or thermal shutdown will set the soft-start latch, resulting in a complete soft-start sequence.The switch driver operates from either the V IN or BST volt-age. An external diode and capacitor are used to generate a drive voltage higher than V IN to saturate the output NPN and maintain high effi ciency. If the BST capacitor voltage is suffi cient, the switch is allowed to operate to 100% duty cycle. If the boost capacitor discharges towards a level insuffi cient to drive the output NPN, a BST pin compara-tor forces a minimum cycle off time, allowing the boost capacitor to recharge.A power good comparator with 30mV of hysteresis trips at 90% of regulated output voltage. The PG output is an open-collector NPN that is off when the output is in regu-lation allowing a resistor to pull the PG pin to a desired voltage.BLOCK DIAGRAM103501fbeither clamp the input voltage or dampen the tank circuit by adding a lossy capacitor in parallel with the ceramic capacitor. For details, see Application Note 88.Output Capacitor SelectionTypically step-down regulators are easily compensated with an output crossover frequency that is 1/10 of the switch-ing frequency. This means that the time that the output capacitor must supply the output load during a transient step is ~2 or 3 switching periods. With an allowable 5% drop in output voltage during the step, a good starting value for the output capacitor can be expressed by:CMax Load StepFrequency V VOUTOUT =•.•005Example:V OUT = 3.3V, Frequency = 1MHz, Max Load Step = 3ACe V FVOUT ==2160053312•.•.µThe calculated value is only a suggested starting value. Increase the value if transient response needs improvement or reduce the capacitance if size is a priority.The output capacitor fi lters the inductor current to generate an output with low voltage ripple. It also stores energy in order to satisfy transient loads and to stabilize the LT3501’s control loop. The switching frequency of the LT3501 deter-mines the value of output capacitance required. Also, the current mode control loop doesn’t require the presence of output capacitor series resistance (E SR). For these reasons, you are free to use ceramic capacitors to achieve very low output ripple and small circuit size.Estimate output ripple with the following equations:V RIPPLE = ∆I L/(8f C OUT) for ceramic capacitors,andV RIPPLE = ∆I L ESR for electrolytic capacitors (tantalum and aluminum)where ∆I L is the peak-to-peak ripple current in the inductor.The RMS content of this ripple is very low, and the RMS current rating of the output capacitor is usually not of concern.Another constraint on the output capacitor is that it must have greater energy storage than the inductor; if the stored energy in the inductor is transferred to the output, you would like the resulting voltage step to be small compared to the regulation voltage. For a 5% overshoot, this require-ment becomesC LIVOUTLIMOUT>⎛⎝⎜⎞⎠⎟102Finally, there must be enough capacitance for good transient performance. The last equation gives a good starting point. Alternatively, you can start with one of the designs in this data sheet and experiment to get the desired performance. This topic is covered more thoroughly in the section on loop compensation.The high performance (low E SR), small size and robustness of ceramic capacitors make them the preferred type for LT3501 applications. However, all ceramic capacitors are not the same. As mentioned above, many of the high value capacitors use poor dielectrics with high temperature and voltage coeffi cients. In particular, Y5V and Z5U types lose a large fraction of their capacitance with applied voltage and temperature extremes. Because the loop stability and transient response depend on the value of C OUT, you may not be able to tolerate this loss. Use X7R and X5R types. You can also use electrolytic capacitors. The ESRs of most aluminum electrolytics are too large to deliver low output ripple. Tantalum and newer, lower ESR organic electrolytic capacitors intended for power supply use, are suitable and the manufacturers will specify the ESR. The choice of capacitor value will be based on the ESR required for low ripple. Because the volume of the capacitor determines its ESR, both the size and the value will be larger than a ceramic capacitor that would give you similar ripple per-formance. One benefi t is that the larger capacitance may give better transient response for large changes in load current. Table 2 lists several capacitor vendors.APPLICATIONS INFORMATION153501fb163501fbTable 2VENDOR TYPE SERIESTaiyo Yuden Ceramic X5R, X7R AVX Ceramic X5R, X7RTantalum KemetTantalum TA Organic AL Organic T491, T494, T495T520A700Sanyo TA/AL Organic POSCAP Panasonic AL Organic SP CAP TDKCeramic X5R, X7RCatch DiodeThe diode D1 conducts current only during switch off time. Use a Schottky diode to limit forward voltage drop to increase effi ciency. The Schottky diode must have a peak reverse voltage that is equal to regulator input voltage and sized for average forward current in normal operation. Average forward current can be calculated from:I I V V V D AVG OUTININ OUT ()•–=()The only reason to consider a larger diode is the worst-case condition of a high input voltage and shorted output. With a shorted condition, diode current will increase to a typical value of 4A, determined by the peak switch current limit of the LT3501. This is safe for short periods of time, but it would be prudent to check with the diode manu-facturer if continuous operation under these conditions can be tolerated.BST Pin ConsiderationsThe capacitor and diode tied to the BST pin generate a voltage that is higher than the input voltage. In most cases a 0.47µF capacitor and fast switching diode (such as the CMDSH-3 or FMMD914) will work well. Almost any type of fi lm or ceramic capacitor is suitable, but the ESR should be <1Ω to ensure it can be fully recharged during the off time of the switch. The capacitor value can be approximated by: C I DCB V V fBST OUT MAX OUT BST MIN =()()()••–•where I OUT(MAX) is the maximum load current, and V BST(MIN) is the minimum boost voltage to fully saturate the switch.Figure 5 shows four ways to arrange the boost circuit. The BST pin must be more than 1.4V above the SW pin for full effi ciency. Generally, for outputs of 3.3V and higher the standard circuit (Figure 5a) is the best. For outputs between 2.8V and 3.3V, replace the D2 with a small Schottky diode such as the PMEG4005. For lower output voltages the boost diode can be tied to the input (Figure 5b). The circuit in Figure 5a is more effi cient because the BST pin current comes from a lower voltage source. Fig-ure 5c shows the boost voltage source from available DC sources that are greater than 3V. The highest effi ciency is attained by choosing the lowest boost voltage above 3V. For example, if you are generating 3.3V and 1.8V and the 3.3V is on whenever the 1.8V is on, the 1.8V boost diode can be connected to the 3.3V output. In any case, you must also be sure that the maximum voltage at the BST pin is less than the maximum specifi ed in the Absolute Maximum Ratings section.The boost circuit can also run directly from a DC voltage that is higher than the input voltage by more than 3V, as in Figure 5d. The diode is used to prevent damage to the LT3501 in case V X is held low while V IN is present. The circuit saves several components (both BST pins can be tied to D2). However, effi ciency may be lower and dissipa-tion in the LT3501 may be higher. Also, if V X is absent, the LT3501 will still attempt to regulate the output, but will do so with very low effi ciency and high dissipation because the switch will not be able to saturate, dropping 1.5V to 2V in conduction.The minimum input voltage of an LT3501 application is limited by the minimum operating voltage (<3V) and by the maximum duty cycle as outlined above. For proper start-up, the minimum input voltage is also limited by the boost circuit. If the input voltage is ramped slowly, or the LT3501 is turned on with its SS pin when the output is already in regulation, then the boost capacitor may not be fully charged. Because the boost capacitor is charged with the energy stored in the inductor, the circuit will rely on some minimum load current to get the boost circuit running properly. This minimum load will depend onAPPLICATIONS INFORMATIONAt power-up, a reset signal sets the soft-start latch and discharges both SS pins to approximately 0V to ensure proper start-up. When both SS pins are fully discharged the latch is reset and the internal 3.25µA current source starts to charge the SS pin.When the SS pin voltage is below 50mV, the V C pin is pulled low which disables switching. This allows the SS pin to be used as an individual shutdown for each channel.As the SS pin voltage rises above 50mV, the V C pin is re-leased and the output is regulated to the SS voltage. When the SS pin voltage exceeds the internal 0.8V reference, the output is regulated to the reference. The SS pin voltage will continue to rise until it is clamped at 2V.In the event of a V IN1 undervoltage lockout, the SHDN pin driven below 1.28V, or the internal die temperature exceeding its maximum rating during normal operation, the soft-start latch is set, triggering a start-up sequence.In addition, if the load exceeds the maximum output switch current, the output will start to drop causing the V C pin clamp to be activated. As long as the V C pin is clamped, the SS pin will be discharged. As a result, the output will be regulated to the highest voltage that the maximum output current can support. For example, if a 6V output is loaded by 1Ω the SS pin will drop to 0.53V, regulating the output at 4V ( 4A • 1Ω ). Once the overload condition is removed, the output will soft-start from the temporary voltage level to the normal regulation point.Since the SS pin is clamped at 2V and has to discharge to 0.8V before taking control of regulation, momentary overload conditions will be tolerated without a soft-start recovery. The typical time before the SS pin takes control is:tC VA SS CONTROLSS()•.=12700µPower Good IndicatorsThe PG pin is the open-collector output of an internal comparator. The comparator compares the FB pin voltage to 90% of the reference voltage with 30mV of hysterisis. The PG pin has a sink capability of 800µA when the FB pin is below the threshold and can withstand 25V when the threshold is exceeded. The PG pin is active (sink capability is reduced in shutdown and undervoltage lockout mode) as long as the V IN1 pin voltage exceeds 1V.Output Tracking/SequencingComplex output tracking and sequencing between chan-nels can be implemented using the LT3501’s SS and PG pins. Figure 9 shows several confi gurations for output tracking/sequencing for a 3.3V and 1.8V application. Independent soft-start for each channel is shown in Figure 9a. The output ramp time for each channel is set by the soft-start capacitor as described in the soft-start section.Ratiometric tracking is achieved in Figure 9b by connecting both SS pins together. In this confi guration, the SS pin source current is doubled (6.5µA) which must be taken into account when calculating the output rise time.By connecting a feedback network from V OUT1 to the SS2 pin with the same ratio that sets V OUT2 voltage, absolute tracking shown in Figure 9c is implemented. The minimum value of the top feedback resistor (R1) should be set such that the SS pin can be driven all the way to ground with 700µA of sink current when V OUT1 is at its regulated voltage. In addition, a small V OUT2 voltage offset will be present due to the SS2 3.25µA source current. This offset can be corrected for by slightly reducing the value of R2. Figure 9d illustrates output sequencing. When V OUT1 is within 10% of its regulated voltage, PG1 releases the SS2 soft-start pin allowing V OUT2 to soft-start. In this case PG1 will be pulled up to 2V by the SS pin. If a greater voltage is needed for PG1 logic, a pull-up resistor to V OUT1 can be used. This will decrease the soft-start ramp time and increase tolerance to momentary shorts.If precise output ramp up and down is required, drive the SS pins as shown in Figure 9e. The minimum value of resistor (R3) should be set such that the SS pin can be driven all the way to ground with 700µA of sink current during power-up and fault conditions.Multiple Input VoltagesFor applications requiring large inductors due to high V IN to V OUT ratios, a 2-stage step-down approach may reduceAPPLICATIONS INFORMATION203501fbSS1V OUT13.3V5ms/DIV 10ms/DIV 10ms/DIVSS1V OUT13.3VSS1V OUT1SS1V OUT1R325kSS1V OUT1PG2PG2PG110ms/DIV10ms/DIVPG1PG1PG2PG2PG1PG1SS1/2LT3501. Place additional vias near the catch diodes. Adding more copper to the top and bottom layers and tying this copper to the internal planes with vias can further reduce thermal resistance. With these steps, the thermal resistance from die (or junction) to ambient can be reduced to θJA = 45°C/W.The power dissipation in the other power components such as catch diodes, boost diodes and inductors, cause additional copper heating and can further increase what the IC sees as ambient temperature. See the LT1767 data sheet’s Thermal Considerations section.Single, Low Ripple 6A OutputThe LT3501 can generate a single, low ripple 6A output if the outputs of the two switching regulators are tied together and share a single output capacitor. By tying the two FB pins together and the two V C pins together, the two channels will share the load current. There are several advantages to this 2-phase buck regulator. Ripple currents at the input and output are reduced, reducing voltage ripple and allowing the use of smaller, less expensive capacitors. Although two inductors are required, each will be smaller than the inductor required for a single-phase regulator. This may be important when there are tight height restric-tions on the circuit. There is one special consideration regarding the 2-phase circuit. When the difference between the input voltage and output voltage is less than 2.5V, then the boost circuits may prevent the two channels from properly sharing current. If, for example, channel 1 gets started fi rst, it can supply the load current, while channel 2 never switches enough current to get its boost capacitor charged.In this case, channel 1 will supply the load until it reaches current limit, the output voltage drops, and channel 2 gets started. Two solutions to this problem are shown in the Typical Applications section.The single 3.3V/6A output converter generates a boost sup-ply from either SW that will service both switch pins. The synchronized 3.3V/12A output converter utilizes undervoltage lockout to prevent the start-up condition.

Outlook Express的设置方
Outlook Express的设置方法Outlook Express是Microsoft(微软)自带的一种电子邮件,简称为OE,是微软公司出品的一款电子邮件客户端,也是一个基于NNTP协议的Usenet客户端。
微软将这个软件与操作系统以及Internet Explorer网页浏览器捆绑在一起。
同时,对于苹果公司“经典”版的麦金塔电脑提供该软件的免费下载(微软不对新版本的Mac OS X操作系统提供该软件,在OS X上微软对应的软件是Microsoft Entourage,Microsoft Entourage是专有商用软件Microsoft Office套装的一部分)。
Office软件内的Outlook与Outlook Express是两个完全不同的软件平台,他们之间没有共享代码,但是这两个软件是设计理念是共通的。
他们之间如此相似的名字使得很多人以为Outlook Express是Outlook软件的“精简版”。
不过Outlook Express并不像Outlook 那样可以和Microsoft Exchange Server相互搭配而有群组软件的功能。
Outlook Express 目前实际上一直是Internet Explorer的一部分,将来似乎也不太可能存在剥离版的OE。
微软承诺“将来的安全扩展”的结果将会是发布新版本的Internet Explorer(当然就包括了OE)。
这个新版的IE/OE将运行在新的“安全”操作平台-Windows Longhorn上。
Outlook Express 设置:(以中文版Outlook Express 6为例)一、首先设置邮件帐号:打开Outlook Express后,单击菜单栏中的“工具”,然后选择“帐号”;二、点击“邮件”标签,点击右侧的“添加”按钮,在弹出的菜单中选择“邮件”;三、在弹出的对话框中,根据提示,输入您的“显示名”,然后点击“下一步”;四、输入您已经申请过的电子邮件地址,如:***@ ,然后点击“下一步”;五、邮件接收服务器您可以选择POP3或IMAP服务器;如果您选择POP3服务器:请输入您邮箱的的POP3和SMTP服务器地址后,再点击“下一步”;POP3服务器: SMTP服务器: (端口号使用默认值)如果您选择IMPA服务器:请输入您邮箱的的IMAP和SMTP服务器地址后,再点击“下一步”;IMAP服务器: SMTP服务器: (端口号使用默认值)POP3(Post Office Protocol 3)即邮局协议的第3个版本,它是规定个人计算机如何连接到互联网上的邮件服务器进行收发邮件的协议。
