证明哥德巴赫猜想特殊方法

2012年第28期(总第43期)科技视界Science&Technology Vision0引言证明前:重点研究数字的数性分类和合数的重要作用,为证明提供资料和数据。

证明时:专门求证(1+1)为两个合数之和,反证(1+1)为两个素数之和成立。

同时研究证明所得数据的“周期”性,使证明(1+1)成立的全覆盖。

1证明前1.1数字性质分析哥德巴赫猜想(1+1)研究者用的都是十进位数。

历来仅将“证明数”奇数P分为素数S和合数f两类,将“被证明数”偶数n统称为偶数。

这些正是(1+1)至今难以得到证明的主要原因之一。

根据求解(1+1)需要和十进位数内的客观存在,每一个数字不论是偶数n或奇数P,都有自身的特性,统称“数性”,记为a。

如按不同的a进行分类,就可最大限度简化(1+1)的研究和求证。

1.2按数性分类1.2.1P和n数性a各有对应的三类1)P a分为:负性“-”,中性“0”和正性“+”,以脚注表示:P-、P0和P+。

素数S合数f的数性从属于所在的P的P a。

2)n a分为:负性“-”,中性“0”和正性“+”,以脚注表示:n-、n0和n+。

1.2.2不同P a、n a表达式P a和n a实为6个连续数,如把十进位数3开始,依次将每一6个连续数组成若干个组合为X,X为自然数。

相邻两X对应6个数之差均为6。

P a和n a表达式如下:1)P a表达式:P-=6X-1,P0=6X-3,P+=6X+12)n a表达式:n-=6X-2,n0=6X,n+=6X+21.2.3验算因n a=P a+P a按a进行配对“d”确认其可行性。

1)可证明(1+1)有效配对n-=P-+P-=(6X1-1)+(6X2-1)=6(X1+X2)-2=6X-2n0=P-+P+=(6X1-1)+(6X2+1)=6(X1+X2)=6Xn+=P++P+=(6X1+1)+(6X2+1)=6(X1+X2)+2=6X+22)无效配对n-=P++P0=(6X1+1)+(6X2-3)=6(X1+X2)-2=6X-2n0=P01+P02=(6X1-3)+(6X2-3)=6(X1+X2)-6=6(X1+X2-1)=6Xn+=P-+P0=(6X1-1)+(6X2-3)=6(X1+X2)-4=6(X1+X2-1)+2=6X+2 1.2.4根据上述可以看出,如已知n a,就知用何P a配对相加,还能从中归纳出,用两个相同或不同P a配对,确定其和n数性的(反向表达亦可)“加法定律”“同性P相加,和n与P同性;异性P相加,和n与P互异”。

SG6841DZ,SG6841SZ,SG6841SZ3,SG6841DZ3, 规格书,Datasheet 资料

OPERATION DESCRIPTION Start-up currentTypical start-up current is only 30uA so that a high resistance, and low-wattage, start-up resistor can be used to minimize power loss. For an AC/DC adapter with universal input range, a 1.5 M Ω, 0.25W, start-up resistor and a 10uF/25V VDD hold-up capacitor are enough for this application.Operating currentOperating current has been reduced to 3mA. The low operating current enables a better efficiency and reduces the requirement of VDD hold-up capacitance.Green Mode OperationThe patented green-mode function provides an off-time modulation to reduce the switching frequency in the light load and no load conditions. The on time is limited for better abnormal or brownout protection. V FB , which is derived from the voltage feedback loop, is taken as the reference. Once V FB is lower than the threshold voltage, switching frequency will be linearly decreased to the minimum green mode frequency around 10kHz (R i =26k Ω).Oscillator OperationA resistor from RI pin to ground will generate a constant current source for SG6841. This current is used to charge an internal capacitor and hence the internal clock and switching frequency are determined. Increase the resistance will decrease the current source and reduce the switching frequency. A 26k Ω resistor R i creates a 50uA constant current I i and generates 65kHz switching frequency. The relation between Ri and switching freauency is:)(kHz )(k R 1690 I PWM f Ω=---------------------------- (1)The range of the PWM oscillation frequency is designed as 50kHz ~ 90kHz.Current sensing and PWM current limitingPeak current mode control is utilized in SG6841 to regulate output voltage and provide pulse by pulse current limiting. The switch current is detected by a sense resistor into the sense pin of SG6841. The PWM duty cycle is determined by this current sense signal and V FB , the feedback voltage. When the voltage on sense pin reaches V COMP = (V FB –1.0)/3, a switch cycle will be terminated immediately. V COMP is internally clamped to a variable voltage around 0.85v for output power limit.Leading Edge BlankingEach time when the power MOSFET is switched on, a turn-on spike will inevitably occur on the sense-resistor. To avoid premature termination of the switching pulse, a 270 nsec leading-edge blanking time is built in. Conventional RC filtering can therefore be omitted. During this blanking period, the current-limit comparator is disabled and it cannot switch off the gate driver.Under-voltage lockout (UVLO)The turn-on and turn-off threshold of SG6841 are fixed internally at 16V/10V. During start-up, the hold-up capacitor must be charged to 16V through the start-up resistor so that SG6841 will be enabled. The hold-up capacitor will continue to supply V DD before the energy can be delivered from auxiliary winding of the main transformer. V DD must not drop below 10V during this start-up process. This UVLO hysteresis window insures that hold-up capacitor is adequate to supply V DD during start-up.Gate Output / Soft DrivingThe SG6841 BiCMOS output stage is a fast totem pole gate driver. Cross conduction has been avoided to minimize heat dissipation, increases efficiency and enhances reliability. The output driver is clamped by an internal 18V Zener diode in order to protect power MOSFET transistors against undesirable gate over voltage. A soft driving waveform is implemented to minimize EMI.Built-in Slope CompensationThe sensed voltage across the current sense resistor is used for current mode control and pulse-by-pulse current limiting. Built-in slope compensation will improve stability or prevent sub-harmonic oscillation of peak current mode control. SG6841 inserts a synchronized positive-going ramp at every switching cycle. Vs-comp = 0.33V.Constant Output Power LimitWhen the SENSE voltage, across the sense resistor Rs, reaches the threshold voltage, around 1.0V, the output GATE drive will be turned off after a small propagation delay t D. This propagation delay will introduce an additional current proportional to t D*Vin/Lp. Since the propagation delay is nearly constant regardless of the input line voltage V IN. Higher input line voltage will result in a larger additional current and hence the output power limit is also higher than that under low input line voltage. To compensate this variation for wide AC input range, the threshold voltage is adjusted by the V IN current. Since VIN pin is connected to the rectified input line voltage through the start-up resistor, a higher line voltage will generate higher V IN current into the VIN pin. The threshold voltage is decreased if the V IN current is increased. Smaller threshold voltage, forces the output GATE drive to terminate earlier, thus reduce the total PWM turn-on time and make the output power equal to that of low line input. This proprietary internal compensation ensures a constant output power limit for wide AC input voltage from 90VAC to 264VAC.Thermal ProtectionAn NTC thermistor Rntc in series with a resistor Ra can be connected from pin RT to ground. A constant current I RT is output from pin RT. The voltage on RT pin can be expressed as V RT = I RT × (Rntc + Ra) in which I RT = 2 x (1.3V / Ri).At high ambient temperature, Rntc will be smaller such that V RT will decrease. When V RT is less than 0.65V (V OTP,START), the PWM duty cycle will be decreased to lower the internal temperature of power supply. If the over heating situation still exists such that V RT decreases further to 0.62V (V OTP,STOP), the PWM will be completely turned off.Limited Power ControlEvery time when the output of power supply is shorted or over loaded, the FB voltage will increase. If the FB voltage is higher than a designed threshold, 4.2V, for longer than 31msec, the PWM output will then be turned off eternally. V DD, the supply voltage for SG6841, will decrease due to the supply current for SG6841. When V DD is lower than the turn-off threshold such as 10V, SG6841 will be totally shut down. Due to the start up resistor, V DD will be charged up to the turn-on threshold voltage 16V until SG6841 is enabled again. If the over loading condition still exists, above protection will take place repeatedly. This will prevent the power supply from being overheated under over loading condition.Noise immunityNoise on the current sense or control signal may cause significant pulse width jitter, particularly in the continuous conduction mode. Slope compensation helps alleviate this problem. Good placement and layout practices should be followed. Avoiding long PCB traces and component leads, locating compensation and filter components near to the SG6841, and increasing the power MOS gate resistance will always help.DISCLAIMERSLIFE SUPPORTSystem General’s products are not designed to be used as components in devices intended to support or sustain human life.

It requiresvery few external components to achieve versatile protections. It is available in a 20-pin SOP package. The patented interleave-switching feature synchronizes the PFC and PWM stages and reduces switching noise. For PFC stage, the proprietary multi-vector control scheme provides a fast transient response in a low-bandwidth PFC loop, in which the overshoot and undershoot of the PFC voltage are clamped. If the feedback loop is broken, the SG6901A shuts off PFC to prevent extra-high voltage on output. Programmable two-level output voltage control reduces the PFC output voltage at low line input to increase the efficiency of the power supply.For the flyback PWM, the synchronized slope compensation ensures the stability of the current loop under continuous-conduction-mode operation. Built-in line-voltage compensation maintains constant output-power limit. Hiccup operation during output overloading is also guaranteed.In addition, SG6901A provides protection functions, such as brownout and RI pin open/short protection.Typical ApplicationPFC / Flyback PWM ControllerSG6901AMARKING DIAGRAMS PIN CONFIGURATIONORDERING INFORMATIONPart Number Pb-Free Package SG6901ASZ20-pin SOPT : S=SOPP : Z=Lead FreeNull=regular package XXXXXXXX : Wafer Lot Y : Year; WW : Week V : Assembly LocationSG6901A TP XXXXXXXXYWWVPFC / Flyback PWM ControllerSG6901APIN DESCRIPTIONSName Pin No. Type FunctionVRMS 1Line-VoltageDetectionLine voltage detection.

Many functions and protections are built in toprovide a compact design. The following sectionsdescribe the operation and function.Switching Frequency and CurrentSourcesThe switching frequency of SG6901A can beprogrammed by the resistor R I connected between RI pinand GND. The relationship is:(kHz))(kΩR1560FIOSC=----------- (1)For example, a 24KΩ resistor R I results in a 65KHzswitching frequency. Accordingly, a constant current, I T,flows through R I:(mA))(kΩR1.2VIIT= ---------------- (2)I T is used to generate internal current reference.Line Voltage Detection (VRMS)Figure 1 shows a resistive divider with low-pass filteringfor line-voltage detection on the VRMS pin. The V RMSvoltage is used for the PFC multiplier, brownoutprotection, and range control.For brownout protection, the SG6901A is disabled with195ms delay time if the voltage V RMS drops below 0.8V.For PFC multiplier and range control, refer to sectionbelow for more details.FIG.1 Line Voltage Detection CircuitPFC Output Voltage Control (RANGE)For an universal input (90 ~ 264V AC) power supplyapplying active boost PFC and flyback as a second stage,the output voltage of PFC is usually designed around250V at low line and 390V at high line. This can improvethe efficiency at low-line input. The RANGE pin(open-drain structure) is used for the two-level outputvoltage setting.Figure 2 shows the RANGE output that programs the PFCoutput voltage. The RANGE output is shorted to groundwhen the V RMS voltage exceeds V RMS-H (1.95V) while it isof high impedance (open) whenever the V RMS voltagedrops below V RMS-L (1.6V). The output voltages can bedesigned using equations:()()V3R//RR//RRVGroundRangeV3RRRVOpenRangeCBCBAOBBAO×+=⇒=×+=⇒=---- (3)FIG.2 Range Control Two-Level Output VoltageProduct Specification PFC / Flyback PWM Controller SG6901A Interleave SwitchingThe SG6901A uses interleaved switching to synchronizethe PFC and flyback stages, which reduces switchingnoise and spreads the EMI emissions. Figure 3 showsoff-time, T OFF, inserted between the turn-off of the PFCgate drive and the turn-on of the PWM.FIG.3 Interleaved Switching PatternPFC OperationThe purpose of a boost active power factor corrector (PFC)is to shape the input current of a power supply. The inputcurrent waveform and phase follow that of the inputvoltage. Average-current-mode control is utilized forcontinuous-current-mode operation for the PFC booster.With the innovative multi-vector control for voltage loopand switching charge multiplier-divider for currentreference, excellent input power factor is achieved withgood noise immunity and transient response. Figure 4shows the total control loop for the average-current-modecontrol circuit of SG6901A.The current source output from the switching chargemultiplier-divider can be expressed as:(µA)VVIKI2RMSEAACMO××= ------------ (4)As shown in Figure 4, the current output from IMP pin,I MP, is the summation of I MO and I MR1. I MR1 and I MR2 areidentical fixed-current sources used to pull high theoperating point of the IMP and IPFC pins since thevoltage across R S goes negative with respect to ground.Constant current sources I MR1 and I MR2 are typically 60µA.Through the differential amplification of the signal acrossR S, better noise immunity is achieved. The output of IEA iscompared with an internal sawtooth and the pulse widthfor PFC is determined. Through the average current-modecontrol loop, the input current I S is proportional to I MO:SS2MORIRI×=×-------------------- (5)According to Equation 5, the minimum value of R2 andmaximum of R S can be determined since I MO should notexceed the specified maximum value.There are different concerns in determining the value ofthe sense resistor R S. The value of R S should be smallenough to reduce power consumption, but large enough tomaintain the resolution. A current transformer (CT) maybe used to improve efficiency of high-power converters.To achieve good power factor, the voltage for V RMS andV EA should be kept as constant as possible, according toEquation 4. Good RC filtering for V RMS and narrowbandwidth (lower than the line frequency) for voltageloop are suggested for better input current shaping. Thetransconductance error amplifier has output impedanceZ O and a capacitor C EA (1µF ~ 10µF) should be connectedto ground. This establishes a dominant pole f1 for thevoltage loop:EAO1CZ21f××=π---------------------- (6)The average total input power can be expressed as:ACEA2RMSEAACRMS2RMSEAACRMSMORMS(rms)IN(rms)INRV2VVRVinVVVIVIVIVPin×=××∝××∝×∝×=---------------- (7)From Equation 7, V EA, the output of the voltage erroramplifier, controls the total input power and the powerdelivered to the load.Product SpecificationPFC / Flyback PWM ControllerSG6901AFIG.4 Average-Current-Mode Control LoopMulti-Vector Error AmplifierAlthough the PFC stage has a low bandwidth voltage loop for better input power factor, the innovative multi-vector error amplifier provides a fast transient response to clamp the overshoot and undershoot of the PFC output voltage. Figure 5 shows the block diagram of the multi-vector error amplifier. When the variation of the feedback voltage exceeds ±5% of the reference voltage, the transconductance error amplifier adjusts its output impedance to increase the loop response.FIG. 5 Multi-Vector Error AmplifierPFC Over-Voltage ProtectionUsing a voltage divider from the output of PFC to the OVP pin, the PFC output voltage can be safely protected. Once the voltage on the OVP pin is over OVP PFC , the OPFC is disabled. THE OPFC is not enabled again until the OVP voltage falls below OVP PFC .Cycle-by-Cycle Current LimitingSG6901A provides cycle-by-cycle current limiting for both PFC and PWM stages. Figure 6 shows the peak current limit for the PFC stage. The PFC gate drive is terminated once the voltage on the ISENSE pin goes below V PK .The voltage of V RMS determines the voltage of V PK . The relationship between V PK and V RMS is shown in Figure 6. The amplitude of the constant current, I P , is determined by the internal current reference according to the equation:IP R 1.2V2 I ×= --------------------- (8)Product Specification PFC / Flyback PWM Controller SG6901AFIG. 6 V RMS Controlled Current LimitingThe peak current of the I SENSE is given by (V RMS<1.05V):SPPSENSE_peakR0.2V-)R(II×= ------------------ (9)Flyback PWM and Slope CompensationAs shown in Figure 7, peak-current-mode control isutilized for flyback PWM. The SG6901A inserts asynchronized 0.5V ramp at the beginning of eachswitching cycle. This built-in slope compensation ensuresstable operation for continuous current-mode operation.FIG. 7 Peak Current Control LoopWhen the IPWM voltage, across the sense resistor,reaches the threshold voltage (0.9V), the OPWM is turnedoff after a small propagation delay t PD-PWM.To improve stability or prevent sub-harmonic oscillation,a synchronized positive-going ramp is inserted at everyswitching cycle.Limited Power ControlEvery time the output of power supply is shorted oroverloaded, the FBPWM voltage increases. If theFBPWM voltage is higher than a designed threshold,FB OPEN-LOOP (4.5V) for longer than t OPEN-PWM (56ms), theOPWM is turned off.As long as the voltage on the VDD pin is larger thanVDD-OFF(minimum operating voltage), the OPWM is notenabled. This protection is reset every t OPEN-PWM-Hiccupinterval. A low-frequency hiccup mode protectionprevents the power supply from being overheated underoverloading conditions.Over-Temperature ProtectionSG6901A provides an OTP pin for over-temperatureprotection. A constant current is output from this pin. If R Iis equal to 24KΩ, the magnitude of the constant current is100µA. An external NTC thermistor must be connectedfrom this pin to ground, as shown as Figure 8. When theOTP voltage drops below V OTP-OFF (1.2V), SG6901A isdisabled and does not recover until OTP voltage exceedsV OTP-ON (1.4V).FIG. 8 OTP FunctionSoft-StartDuring start-up of PWM stage, the SS pin charges anexternal capacitor with a constant current source. Thevoltage on FBPWM is clamped by the SS voltage duringstart-up. In the event of a protected condition and/orPWM disabled, the SS pin quickly discharges.Gate DriversSG6901A output stage is a fast totem-pole gate driver.The output driver is clamped by an internal 18V Zenerdiode to protect the external power MOSFET.。

SG5841/J provides many protection functions. In addition to cycle-by-cycle current limiting, the internal open-loop protection circuit ensures safety should an open-loop or output-short-circuit failure occur. PWM output is disabled until VDD drops below the UVLO lower limit, then the controller starts again. An external NTC thermistor can be applied for over-temperature protection.

Product Specification
SG5841/J PIN CONFIGURATION
To minimize standby power consumption, a proprietary green-mode function provides off-time modulation to continuously decrease the switching frequency at light-load conditions. This green-mode function enables the power supply to meet international power conservation requirements. To further reduce power consumption, SG5841/J is manufactured using the BiCMOS process. This allows a low start-up current, around 14µA, and an operating current of only 4mA. As a result, a large start-up resistance can be used.

(300V)NOTES:1. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.2. Proper power-supply sequencing is recommended for the CMOS device. Always sequence V S on first, followed by the inputs and outputs. CAUTIONThis integrated circuit can be damaged by ESD if you don’t pay attention to ESD protection. SGMICRO recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.SGMICRO reserves the right to make any change in circuit design, specification or other related things if necessary without notice at any time.

语法的学习是直接告知学生关于某个语法点的定义，然后解释用法1、2、3等等，给出和该语法点相关的练习句子并重复相同的练习，这种方式我们称之为：演绎法-m ét h ode d éd u ct i v e。

在传统教学法中，教师的角色是绝对的主导者，从教材或者文档的选择、语法点的教授到练习的制作都由教师决定，课堂中的主导语言是母语，而单方向的输出（老师到学生）也是一大特点，提问和回答问题的主导权都在教师手上，所以我们又说教师是课堂的主人。

除此之外，传统教学法的主要目的是：* 让学生掌握语法点* 拓展阅读和翻译能力而它的不足之处是：* 对记忆力的要求很高* 想要达到应用自如的能力会较为困难，尤其是在口语和听力方面你是否还记得以前学习语言的教材？第一个部分：给你一个单词表，左边英语（外语），右边翻译的中文，拿去背吧。

然后老师说明天要听写，为了不被惩罚，能做的就是回家死记硬背，最后的学习效果就不言而喻了。

不过这种教学法会更适用于拉丁语和希腊语的学习，也就是我们说的对于“死亡语言-d e s l a n g u es mo r t es”的学习，没有常规的对话场景（除了想象的练习场景），学习这些语言的主要目的是将其翻译成其他语言。

2、直接教学法-19世纪末到20世纪初期，法国对外开放交流，需要的不仅仅是文绉绉（文学）的语言了，我们需要的语言是作为一种工具的存在，目的是为了促进社会、经济、政治、文化的发展和交流，所以这个时期的语言学习目标就变成了“实际应用”，而语言的角色则变成了“交流工具”。

所谓的直接教学法，就是按照最自然的语言学习路径来，也就是像一个婴儿学习语言那样，不管是否能听得懂，直接说，不借助其他任何语言（除了手势动作）。

SG6846A中文资料

元器件交易网Product Specification Highly Integrated Green-Mode PWM ControllerSG6846Aconsumption, a proprietary green-mode function provides off-time modulation to continuously decrease the switching frequency under light-load conditions. Under zero-load conditions, the power supply enters burst-mode. The SG6846A is especially designed for SMPS with surge-current output, incorporated with a two-level OCP function. Besides the cycle-by-cycle current limiting, if the switching current is higher than two thirds the peak-current threshold for 1700ms, over-current protection is activated and the SG6846A latches off. If the switching current is higher than two thirds the peak-current threshold for 100ms and the voltage on the VDD pin is higher than VDD-OFF + 1V, the PWM pulses are latched off immediately once VDD voltage is lower than VDD-OFF + 1V; useful if an output short-circuit occurs. SG6846A also integrates a frequency hopping function that reduces EMI emission of a power supply with minimum line filters. Its built-in synchronized slope compensation provides proprietary internal compensation for constant output power limit over a universal AC input range. Also, the gate output is clamped at 18V to protect the external MOSFET from over-voltage damage. Internal soft-start is built-in to reduce stress on the MOSFET and start-up current during power-on period. Other protection functions include: AC input brownout protection with hysteresis, VDD over-voltage protection, and over-temperature protection. For over-temperature protection, an external NTC thermistor can be applied to sense the ambient temperature. When OCP, VDD OVP, or OTP are activated, an internal latch circuit is used to latch-off the controller. The PWM pulses stay latched off until the power supply is unplugged from the main outlet. SG6846A is available in an 8-pin SOP package.FEATURESTwo-level OCP with 1700ms delay time Output short-circuited delay time: 100ms Low start-up current (8µA) Low operating current (3.7mA) Peak-current mode operation with cycle-by-cycle current limiting Programmable PWM frequency with frequency hopping PWM frequency continuously decreasing with burst mode at light loads VDD over-voltage protection (OVP) AC input brownout protection with hysteresis and constant output power limit Constant output power limit (full AC input range) Internal latch circuit for OVP, OTP, and OCP Built-in soft-start Open-loop protection with 1700ms delay timeAPPLICATIONSGeneral-purpose switch-mode power flyback power converters, including: Power adapters Open-frame SMPS Specifically fit for SMPS with surge-current output (such as for printers, scanners, motor drivers, etc.) supplies andDESCRIPTIONThe highly integrated SG6846A series of PWM controllers provides features to enhance the performance of flyback converters.

The signal from the external compensation circuit is fed into this pin. The PWM duty cycle is determined in response to the signal from this pin and the current-sense signal from Pin 6. Line-voltage detection. The line-voltage detection is used for brownout protection with hysteresis. Constant output power limit over a universal AC input range is also achieved using this VIN pin. Consider adding a low-pass filter to filter out line ripple on the bulk capacitor. A resistor from the RI pin to ground generates a reference current source that determines the switching frequency. Increasing the resistance reduces the switching frequency. Using a 26kΩ resistor results in a 65kHz switching frequency. For over-temperature protection, an external NTC thermistor is connected from this pin to the GND pin. The impedance of the NTC decreases at high temperatures. Once the voltage of the RT pin drops below a threshold, PWM output is disabled.3VIN4RI5RT6SENSECurrent sense. The sensed voltage is used for peak-current-mode control and cycle-by-cycle current limiting. If the switching current is higher than two thirds of the peak-current threshold for longer than 100ms and VDD is higher than 12V and lasts for 1700ms, over-current Current Sense protection is activated. If an output short over-current also occurs and lasts for 100ms and VAUX is lower than 12V, SG6846A turns off immediately. This two-level OCP feature is especially suitable for SMPS with surge current output. It also has built-in 5ms soft-start time as switching frequency operates at 65KHz.

Version 1.1.1 (IAO33.0059.B1)-8- • September 26, 2007元器件交易网Product Specification Highly Integrated Green-Mode PWM ControllerSG6846AOPERATION DESCRIPTIONStart-up Operation The turn-on/turn-off thresholds are fixed internally at 16.5V/10.5V. To enable the SG6846A during start-up, the hold-up capacitor must first be charged to 16.5V through the start-up resistor. The hold-up capacitor continues to supply VDD before energy can be delivered from the auxiliary winding of the main transformer. The VDD must not drop below 10.5V during this start-up process. This UVLO hysteresis window ensures that the hold-up capacitor can adequately supply VDD during start-up. The typical start-up current is only 8µA, which allows a high-resistance, low-wattage start-up resistor to minimize power loss. A 1.5MΩ/0.25W start-up resistor and a 10µF/25V VDD hold-up capacitor are sufficient for a universal input range. The required operating current has been reduced to 3.7mA, which enables higher efficiency and reduces the VDD hold-up capacitance requirement. corresponding 65kHz switching frequency. The relationship between RI and the switching frequency is:fPWM(kHz) = R1690 ) (kΩI----------------------------(1)If an open-circuit or short-circuit to ground occurs at the RI pin, the internal protection circuit immediately shuts down the controller.Two-Level Over-Current Protection The cycle-by-cycle current limiting shuts down the PWM immediately when the switching current is over the peak-current threshold. Additionally, when the switching current is higher than two thirds the peak-current threshold, the internal counter counts down. When the total accumulated counting time is more than around 1600ms (RI=26kΩ), the controller is latched off the internal counter counting up. When the switching current is lower than two thirds of the peak current threshold, the internal counter counts down. When the total accumulated counting time is more than about 1700ms (RI=26kΩ), the controller is latched off. This two-level OCP protection and up/down counter are especially designed for SMPS with surge current for printers, scanners, motor drivers, etc.Green-Mode Operation The proprietary green-mode function provides off-time modulation to continuously decrease the switching frequency under light-load conditions. Maximum on-time is limited to provide protection against abnormal conditions. To further reduce power consumption under zero-load condition, the PWM oscillator is completely turned off and the power supply enters burst-mode. This green-mode function dramatically reduces power consumption under light-load and zero-load conditions. Power supplies using the SG6846A can meet even the most restrictive international regulations regarding standby power consumption.Constant Output Power Limit For constant output power limit over a universal input-voltage range, the peak-current threshold is adjusted by the voltage of the VIN pin. Since the VIN pin is connected to the rectified AC input line voltage through the resistive divider, a higher line voltage generates a higher VIN voltage. The threshold voltage decreases as the VIN voltage increases, making the maximum output power at high-line input voltage equal to that at low-line input.Oscillator Operation A resistor connected from the RI pin to GND generates a reference current source used to determine the PWM frequency. Increasing the resistance decreases the amplitude of the current source and reduces the PWM frequency. Using a 26kΩ resistor results in a© System General Corp. Version 1.1.1 (IAO33.0059.B1)-9- • September 26, 2007元器件交易网Product Specification Highly Integrated Green-Mode PWM ControllerSG6846ABrownout Protection Since the VIN pin is connected through a resistive divider to the rectified AC input line voltage, it can also be used for brownout protection. If the VIN voltage is less than 0.7V, the PWM output shuts off. If the VIN voltage is over 0.9V, the PWM output turns on again. The hysteresis window for ON/OFF is around 0.2V. VDD Over-voltage Protection VDD over-voltage protection is built-in to prevent the controller from over-voltage destruction. When VDD voltage is over 23.6V, the SG6846A is latched off.Noise Immunity Noise from the current sense or the control signal may cause significant pulse jitter, particularly in continuous-conduction mode. Slope compensation helps alleviate this problem. Good placement and layout practices should be followed. Avoid long PCB traces and component leads. Compensation and filter components should be located near the SG6846A. Usually an RC network is put on between sensing resistor and the CS pin to filter high-frequency switching noise, as shown Figure 1.Over-Temperature Protection An external NTC thermistor can be connected from the RT pin to GND.

The on-chip +5.1 volt reference is trimmed to ±1% initial accuracy and the input common-mode range of the error amplifier includes the reference voltage, eliminating external potentiometers and divider resistors. A Sync input to the oscillator allows multiple units to be slaved together, or a single unit to be synchronized to an external system clock. A single resistor between the C T pin and the Discharge pin provides a wide range of deadtime adjustment. These devices also feature built-in soft-start circuitry with only a timing capacitor required externally. A Shutdown pin controls both the soft-start circuitryand the output stages, providing instantaneous turn-off with soft-start recycle for slow turn-on. These functions are also controlled by an undervoltage lockout which keeps the outputs off and the soft-start capacitor discharged for input voltages less than that required for normal operation. Another unique feature of these PWM circuits is a latch following the comparator. Once a PWM pulse has been terminated for any reason, the outputs will remain off for the duration of the period. The latch is reset with each clock pulse. The output stages are totem-pole designs capable of sourcing or sinking in excess of 200mA. The SG1525A output stage features NOR logic, giving a LOW output for an OFF state. The SG1527A utilizes OR logic which results in a HIGH output level when OFF.BLOCK DIAGRAMSG1525A/SG2525A/SG3525A SG1527A/SG2527A/SG3527AFIGURE 1 - OSCILLATOR SCHEMATICERROR AMPLIFIER SECTION FIGURE 3 - OSCILLATOR DISCHARGE TIME VS.

The V C terminal is switched to ground by the totem-pole source transistors on alternate oscillator cycles.In conventional push-pull bipolar designs, forward base drive is controlled by R 1 - R 3 . Rapid turn-off times for the power devices are achieved with speed-up capacitors C 1 and C 2 .OUTPUT SECTIONAPPLICATION INFORMATION (continued) SHUTDOWN OPTIONS1. Use an external transistor or open-collector comparator to pull down on the Comp terminal. This will set the PWM latch turning off both outputs. If the shutdown signal is momentary, pulse-by-pulse protection can be accomplished as the PWM latch will be reset with each clock pulse.2. The same results can be accomplished by pulling down on the Soft-Start terminal with the difference that on this pin, shutdown will not affect the amplifier compensation network but must discharge any Soft-Start capacitor.3. Apply a positive-going signal to the Shutdown terminal. This will provide most rapid shutdown of the outputs but will not immediately set the PWM latch if there is a Soft-Start capacitor. This capacitor will discharge but with a current of approxi-mately twice the charging current.4. The shutdown terminal can be used to set the PWM latch ona pulse-by-pulse basis if there is no external capacitance on Soft-Start terminal. Slow turn-on may still be accomplished by applying an external capacitor, blocking diode, and charging resistor to the comp terminal.
