LED的调光原理分析与设计实例

LED的调光原理分析与设计实例2.1 如何实现PWM调光具体实现PWM调光的方法就是在LED的负载中串入一个MOS开关管(图8),这串LED的阳极用一个恒流源供电。

图8. 用PWM信号快速通断LED串然后用一个PWM信号加到MOS管的栅极,以快速地开关这串LED。

从而实现调光。

也有不少恒流芯片本身就带一个PWM的接口,可以直接接受PWM信号,再输出控制MOS开关管。

那么这种PWM调光方法有那些优缺点呢?2.2脉宽调制调光的优点1.不会产生任何色谱偏移。

因为LED始终工作在满幅度电流和0之间。

2.可以有极高的调光精确度。

因为脉冲波形完全可以控制到很高的精度,所以很容易实现万分之一的精度。

3.可以和数字控制技术相结合来进行控制。

因为任何数字都可以很容易变换成为一个PWM信号。

4.即使在很大范围内调光,也不会发生闪烁现象。

因为不会改变恒流源的工作条件(升压比或降压比),更不可能发生过热等问题。

2.3 脉宽调光要注意的问题1.脉冲频率的选择因为LED 是处于快速开关状态,假如工作频率很低,人眼就会感到闪烁。

为了充分利用人眼的视觉残留现象,它的工作频率应当高于100Hz,最好为200Hz。

2.消除调光引起的啸声:虽然200Hz 以上人眼无法察觉,可是一直到20kHz 却都是人耳听觉的范围。

这时候就有可能会听到丝丝的声音。

解决这个问题有两种方法,一是把开关频率提高到20kHz 以上,跳出人耳听觉的范围。

但是频率过高也会引起一些问题,因为各种寄生参数的影响,会使脉冲波形(前后沿)产生畸变。

这就降低了调光的精确度。

另一种方法是找出发声的器件而加以处理。

实际上,主要的发声器件是输出端的陶瓷电容,因为陶瓷电容通常都是由高介电常数的陶瓷所做成,这类陶瓷都具有压电特性。

在200Hz 的脉冲作用下就会产生机械振动而发声。

解决的方法是采用钽电容来代替。

不过,高耐压的钽电容很难得到,而且价钱很贵,会增加一些成本。

第二部分采用交流电源的LED 调光三.用可控硅对LED 调光普通的白炽灯和卤素灯通常采用可控硅来调光。

It is designed to drive LED devices. The device includes a high-voltage power switch and a circuit to allow start-up directly from the rectified mains voltage. Furthermore the device includes high-voltage circuitry to supply the phase cut dimmer.For dimmable applications, integrated dedicated circuitry optimizes the dimming curve.SSL2101主要特性:Easy migration to existing lighting control infrastructure, TRIAC and transistor dimmersSupports majority of available dimming solutionsValley switching efficiency is optimized by built-in dedicated circuitryBuilt-in demagnetization detectionThe IC has built-in OverTemperature Protection (OTP)Short-Winding Protection (SWP) and OverCurrent Protection (OCP)The IC has internal VCC generation that allows start-up from rectified mains voltageNatural dimming curve by logarithmic correctionSSL2101应用:The SSL2101 is suitable for different power requirements, these include:SSL, retro-fit lamps, e.g. GU10, up to a maximum of 10 WLED modules, separate power supplies, e.g. LED spots, down-lights, up to a maximum of 15 WLED strings, e.g. retail display, up to a maximum of 15 W图1.SSL2101方框图图2.SSL2101反激应用配置框图图3.SSL2101典型的反激应用电路图图4.SSL2101典型的反激应用和元件电路图SSL2101/2102 12W调光LED驱动器The SSL2101/2102 12 W LED driver is a solution for a professional application with multiple high power LEDs that requires galvanic isolation and a safe output voltage. It is mains dimmable for both forward phase (TRIAC) dimmers, and reverse phase (Transistor)dimmers. It can generate up to 16 W output power, which is equal to a 100 W incandescent lamp (at 63 Lumen/W). Examples are shelf lighting, down lighting, LED lighting for bathrooms etc.The design gives an example of how to make a drive that is suitable for small form factor applications like retrofit lamps.The board needs to be connected to mains voltage. Touching the reference board during operation must be avoided at all times. An isolated housing is obligatory when used in uncontrolled, non laboratory environments. Even though the secondary circuit with LED connection has a galvanic isolation, this isolation is not according to any regulated norm. Galvanic isolation of the mains phase using a variable transformer is always recommended.The board can be optimized for a 230 V (AC) (50 Hz) or for a 120 V (AC) (60 Hz) mains source. Besides themains voltage optimization, the board is designed to work with multiple high power LEDs with a total working voltage of between 9 V and 23 V.The output current can be limited using trimmer R20. On request, a dedicated LED load can be delivered that is to be connected to K3. Connector K2 can be used to attach other LED loads. The output voltage is limited to 25 V. When attaching a LED load to an operational board (hot plugging) an inrush peak current will occur due to discharge of capacitor C6.After frequent discharges, the LEDs may deteriorate or become damaged.图4.12W调光LED驱动器外形图图5.12W调光LED驱动器电路图材料清单(BOM)(230V AC):材料清单(BOM)(120V AC):详情请见:。

Placing a high-value electrolytic capacitor on the input (10-μF minimum) and output pin(s) is recommended when the output load is heavy. This precaution reduces power-supply transients that may cause ringing on the input. Additionally, bypassing the output with a 0.01-μF to 0.1-μF ceramic capacitor improves the immunity of the device to short-circuit transients.Over-current and Short Circuit ProtectionAn internal sensing FET is employed to check for over-current conditions. Unlike current-sense resistors, sense FETs do not increase the series resistance of the current path. When an overcurrent condition is detected, the device maintains a constant output current and reduces the output voltage accordingly. Complete shutdown occurs only if the fault stays long enough to activate thermal limiting.Three possible overload conditions can occur. In the first condition, the output has been shorted to GND before the device is enabled or before V IN has been applied. The AP2101/AP2111 senses the short circuit and immediately clamps output current to a certain safe level namely I LIMIT.In the second condition, an output short or an overload occurs while the device is enabled. At the instance the overload occurs, higher current may flow for a very short period of time before the current limit function can react. After the current limit function has tripped (reached the over-current trip threshold), the device switches into current limiting mode and the current is clamped at I LIMIT.In the third condition, the load has been gradually increased beyond the recommended operating current. The current is permitted to rise until the current-limit threshold (I TRIG) is reached or until the thermal limit of the device is exceeded. The AP2101/AP2111 is capable of delivering current up to the current-limit threshold without damaging the device. Once the threshold has been reached, the device switches into its current limiting mode and is set at I LIMIT.To protect against short circuit to GND at extremely low temperature (< -30o C), a minimum 120-μF electrolytic capacitor on the output pin is recommended. A correct capacitor type with capacitor voltage rating and temperature characteristics must be properly chosen so that capacitance value does not drop too low at the extremely low temperature operation. A recommended capacitor should have temperature characteristics of less than 10% variation of capacitance change when operated at extremely low temp. Our recommended aluminum electrolytic capacitor type is Panasonic FC series.At low input voltage condition (V IN < 3V), the short circuit protection current may rise as high as twice the typical value.FLG ResponseWhen an over-current or over-temperature shutdown condition is encountered, the FLG open-drain output goes active low after a nominal 7-ms deglitch timeout. The FLG output remains low until both over-current and over-temperature conditions are removed. Connecting a heavy capacitive load to the output of the device can cause a momentary over-current condition, which does not trigger the FLG due to the 7-ms deglitch timeout. The AP2101/AP2111 is designed to eliminate false over-current reporting without the need of external components to remove unwanted pulses.Power Dissipation and Junction TemperatureThe low on-resistance of the internal MOSFET allows the small surface-mount packages to pass large current. Using the maximum operating ambient temperature (T A) and R DS(ON), the power dissipation can be calculated by:P D = R DS(ON)× I2分销商库存信息:DIODESAP2111SG-13AP2101MPG-13AP2101SG-13 AP2111MPG-13。

8.1 启动和欠电压锁定(UVLO)
最初,IC从经过整流的市电电压上自行供电。一旦管脚VCC上的电压超过VCC(启动) 电平,IC马上开始切换,来自市电电压的供电停止,变压器的辅助绕组能够马上接管 供电,以实现高效率工作。或者,IC也能通过连接到高压的泄放电阻器来供电。不过, 需要注意IC的最大VCC电压额定值。 如果由于某些原因使得辅助电源不够用,那么高压电源也能给IC供电。一旦管脚VCC 上的电压下降到低于VCC(UVLO)电平,且内部提供的电流足够,IC会马上停止切换并 重新开始从经过整流的市电电压上供电。

振荡器的频率由管脚RC和管脚RC2上的外部电阻器和电容器设定。外部电容器被快 速充电到VRC(最大)电平;然后,从新的初级励磁开始,它放电到VRC(最小)电平。 因为放电是指数关系,所以在低占空比时,占空比对调节电压的相对敏感度几乎等于 高占空比时的敏感度。与具有线性锯齿振荡器的PWM系统相比,这在占空比范围内 导致了比较恒定的增益。在低占空比下的稳定操作容易实现。当V亮度高时,可以使用 公式1来估计转换器的频率:

调光原理

调光原理

LED的调光原理分析与设计实例作为一种光源,调光是很重要的。

不仅是为了在家居中得到一个更舒适的环境,在今天来说,减少不必要的电光线,以进一步实现节能减排的目的是更加重要的一件事。

而且对于LED 光源来说,调光也是比其他荧光灯、节能灯、高压钠灯等更容易实现,所以更应该在各种类型的LED 灯具中加上调光的功能。

第一部分采用直流电源LED 的调光技术一.用调正向电流的方法来调亮度要改变LED 的亮度,是很容易实现的。

首先想到的是改变它的驱动电流,因为LED 的亮度是几乎和它的驱动电流直接成正比关系。

图1 中显示了Cree 公司的XLampXP-G 的输出相对光强和正向电流的关系。

图1. XLampXP-G 的输出相对光强和正向电流的关系由图中可知,假如以350mA 时的光输出作为100%,那么200mA 时的光输出就大约是60%,100mA 时大约是25%。

所以调电流可以很容易实现亮度的调节。

1.1 调节正向电流的方法调节LED 的电流最简单的方法就是改变和LED 负载串联的电流检测电阻(图2a),几乎所有DC-DC 恒流芯片都有一个检测电流的接口,是检测到的电压和芯片内部的参考电压比较,来控制电流的恒定。

但是这个检测电阻的值通常很小,只有零点几欧,如果要在墙上装一个零点几欧的电位器来调节电流是不大可能的,因为引线电阻也会有零点几欧了。

所以有些芯片提供一个控制电压接口,改变输入的控制电压就可以改变其输出恒流值。

例如凌特公司的LT3478(图2b)只要改变R1 和R2 的比值,也可以改变其输出的恒流值。

图2. 输出恒流值的调节1.2 调正向电流会使色谱偏移然而用调正向电流的方法来调亮度会产生一个问题,那就是在调亮度的同时也会改变它的光谱和色温。

因为目前白光LED 都是用兰光LED 激发黄色荧光粉而产生,当正向电流减小时,蓝光LED 亮度增加而黄色荧光粉的厚度并没有按比例减薄,从而使其光谱的主波长增长,具体实例如图3 所示。

AC-DC 非隔离式LED 驱动电路的设计

AC-DC 非隔离式LED 驱动电路的设计

AC-DC 非隔离式LED驱动电路的设计一、简单阻容降压LED驱动电路电路是直接采用电容作为限流元件,在此电路中,由于电容上的分压几乎达到了全部电源电压,所以具有良好的限流特性,当电源电压在±10%波动时,输出电流也在≤±10%内波动,只要在设计中把LED 的额定值留有一定的裕量,就能保证在电源电压波动时LED 仍处于良好的工作状态。

由于电容的介质损耗极小,所以电路的损耗很小,电阻R 的作用是在断电时,保证电容上的电压能及时放掉,其阻值可≥3MΩ,每组串联的LED 中,可加有一个IN4007 二极管,当两组串联的LED 有一个内部开路时,另一组有可能被反向电压击穿,如串入一个IN4007 二极管,则可保护剩余的LED 不损坏,当然IN4007 的加入也使效率略有下降,(当输出电流30mA 时,IN4007 上的功耗约0.02W)。

对于一体化小夜灯,可省略IN4007,此时这一驱动电路效率≥90%。

用此驱动电路做成的LED 小夜灯,效率高于采用气体放电光源的小夜灯,并且使用寿命远大于采用其它光源的小夜灯。

此电路在30 个LED 串联时还能稳定工作。

但是此电路输出的光具有一定的频闪(在50Hz 时有100Hz 的频闪),不适用于运动物的照明场合,并且使用时LED 应做成不可触及,否则将影响安全。

注意﹐大部分应用电路中没有连接压敏电阻或瞬变电压抑制晶体管﹐建议连接上﹐因压敏电阻或瞬变电压抑制晶体管能在电压突变瞬间( 如雷电﹑大用电设备起动等 )有效地将突变电流泄放﹐从而保护二级关和其它晶体管﹐它们的响应时间一般在微毫秒级 .电路工作原理﹕电容C1的作用为降压和限流﹕大家都知道﹐电容的特性是通交流﹑隔直流﹐当电容连接于交流电路中时﹐其容抗计算公式为﹕XC = 1/2πf C式中﹐XC 表示电容的容抗﹑f 表示输入交流电源的频率﹑C 表示降压电容的容量.流过电容降压电路的电流计算公式为﹕I = U/XC式中 I 表示流过电容的电流﹑U 表示电源电压﹑XC 表示电容的容抗在220V﹑50Hz的交流电路中﹐当负载电压远远小于220V时﹐电流与电容的关系式为﹕I = 69C 其中电容的单位为uF﹐电流的单位为mA下表为在220V﹑50Hz的交流电路中﹐理论电流与实际测量电流的比较电阻R1为泄放电阻﹐其作用为﹕当正弦波在最大峰值时刻被切断时﹐电容C1上的残存电荷无法释放﹐会长久存在﹐在维修时如果人体接触到C1的金属部分﹐有强烈的触电可能﹐而电阻R1的存在﹐能将残存的电荷泄放掉﹐从而保证人﹑机安全.泄放电阻的阻值与电容的大小有关﹐一般电容的容量越大﹐残存的电荷就越多﹐泄放电阻就阻值就要选小些.经验数据如下表﹐供设计时参考﹕D1 ~ D4的作用是整流﹐其作用是将交流电整流为脉动直流电压.C2﹑C3的作用为滤波﹐其作用是将整流后的脉动直流电压滤波成平稳直流电压压敏电阻( 或瞬变电压抑制晶体管 )的作用是将输入电源中瞬间的脉冲高压电压对地泄放掉﹐从而保护LED不被瞬间高压击穿.LED串联的数量视其正向导通电压( Vf )而定﹐在220V AC电路中﹐最多可以达到80个左右.组件选择﹕电容的耐压一般要求大于输入电源电压的峰值﹐在220V,50Hz的交流电路中时﹐可以选择耐压为400伏以上的涤纶电容或纸介质电容.D1 ~D4 可以选择IN4007.滤波电容C2﹑C3的耐压根据负载电压而定﹐一般为负载电压的1.2倍.其电容容量视负载电流的大小而定. 下列电路图为其它形式的电容降压驱动电路﹐供设计时参考﹕D1 ~ D4的作用是整流﹐其作用是将交流电整流为脉动直流电压.C2﹑C3的作用为滤波﹐其作用是将整流后的脉动直流电压滤波成平稳直流电压压敏电阻( 或瞬变电压抑制晶体管 )的作用是将输入电源中瞬间的脉冲高压电压对地泄放掉﹐从而保护LED不被瞬间高压击穿.LED串联的数量视其正向导通电压( Vf )而定﹐在220V AC电路中﹐最多可以达到80个左右.组件选择﹕电容的耐压一般要求大于输入电源电压的峰值﹐在220V,50Hz的交流电路中时﹐可以选择耐压为400伏以上的涤纶电容或纸介质电容.D1 ~D4 可以选择IN4007.滤波电容C2﹑C3的耐压根据负载电压而定﹐一般为负载电压的1.2倍.其电容容量视负载电流的大小而定.二、可控硅构成的阻容降压LED驱动电路三、线性简易设计方案四、ROHM公司BP5061设计的5V/350mA开关型LED驱动电路五、台硕电子TAC9918设计的LED驱动电路六、集成恒流源NUD4001 的LED 驱动电路七、TAC9910设计的开关型LED驱动电路八、荷兰Philips菲力普公司TEA152X设计的LED驱动器九、韩国动运国际DW8520设计的开关型LED驱动电路十、深圳敦泰科技FT6610DB1设计的开关型LED驱动电路十一、HUF604设计的开关型LED驱动电路十二、Onsemi公司CAT4240设计的开关型LED驱动电路十三、Onsemi公司NCP1200/NCP1216设计的开关型LED驱动电路十四、Addtk 广鹏科技A704设计的开关型LED驱动电路十五、芯联半导体CL6804/CL6808设计的开关型LED驱动电路十六、Consonance 如韵电子CN5616设计的开关型LED驱动电路十七、IR公司IRS2541设计的开关型LED驱动电路十八、PI公司LNK306设计的开关型LED驱动电路十九、National美国国家半导体LM3445设计的开关型LED驱动电路二十、NK南科公司ADT0160设计的四路跑马灯二十一、安森美NCP1216设计的开关型LED驱动电路二十二、安森美NUD4011设计的线性LED驱动电路二十三、安森美NCP3065设计的开关型LED驱动电路二十四、PI公司使用填峰电路来改善功率系数的9 W LED驱动器二十五、PI公司设计的开关型LED驱动电路二十六、PI公司LNK306设计的开关型LED驱动电路二十七、三肯公司LC5205D/5210D设计的高功率因数LED驱动电路二十八、三肯公司STR0W6251设计的开关型LED驱动电路二十九、三肯公司SPI-9150设计的开关型LED驱动电路三十、三肯公司SSC2001设计的开关型LED驱动电路三十一、Supertex美国超科HV9906设计的带PFC功能的LED驱动电路三十二、Supertex美国超科HV9910设计的开关型LED驱动电路三十三、Supertex美国超科HV9921/9922/9923设计的LED驱动电路三十五、Supertex美国超科HV9931设计的PFC功能LED驱动电路••••••三十六、ST公司L6561设计的开关型LED驱动电路三十七、普诚科技股份有限公司PT6901设计的LED驱动电路三十八、华润矽威公司PT4115设计的MR16射灯LED驱动电路三十九、华润矽威公司PT4107设计的宽范围开关型LED驱动电路四十、荷兰NXP恩智浦公司SSL2101构成的LED驱动电路四十一、Sanyo三洋公司LA5121设计的开关型LED驱动电路四十二、Sanyo三洋公司LA5121设计的开关型LED驱动电路。

Traic Dimming

Ⅰ.调光原理介绍:1.典型的可控硅调光器原理(据说是市面90%的调光器原理):其基本原理陈述如下:当220VAC电压加可控硅U1两端时,由于R2,R,C3,组成的RC充电电路有一个充电时间,电容上的电压是从0V开始充电的,并且可控硅U1的驱动极串联有一个DIAC(双向触发二极管,一般是30V左右),因此可控硅可靠截止,此时C3上的电压慢慢上升,上升到30V时,DIAC触发导通,U1驱动极导通,可控硅可靠导通,那么此时可控硅两端的电压瞬间变为零,C3通过R,R2迅速放电,当C3电压跌落到30V以下时DIAC截止,那么可控硅如果通过的电流大于其保持电流,U1继续导通,这个是可控硅基本特性,如果低于保持电流将会截止,那么下一个周期重复上门的讲述;其中非常关键的参数有:A.可控硅的保持电流,目前市面上的一般是7MA到75MA(驱动电流则是7MA到100MA),导通后可控硅回路的电流必须要大于这个值才能导通,否则会关断;B.RC充电回路,我们知道,C这个值一般是定死的,那么相位是如何调节的呢,就是通过调R,R越大充电时间越长,那么导通时间也越长,那么导通角度也会变得越大,反之导通角度越小。

目前市面上的可控硅一般可以将相位角调节到120度,也就是说可以将180度的正弦波切掉120度角,只剩下60度角波形通过;2.可控硅带不同负载的情形:当可控硅能正常运行的时候,负载不同回路会有什么不同表现呢?Ⅱ.关键参数设计建议:下面重点讲述关键参数设计方法,主PWM部分为普通的单级PFC电气结构,类似于FAN7527,工作在DCM模式,能够实现功率因数,与一般电源控制芯片很大的不同的地方,芯片集成了三个很重要的控制部分:可控硅电流回路保持电路设计;DAMPER回路设计;线性调光系统设计;1.保持回路设计:保持回路电路部分如下主要由RSBLEED,RWBLEED,WEAK BLEEDER CONTROL电路组成,WEAK BLEEDER回路的主要任务是检测整个回路电流,如果电流少于一定值(也就是根据可控硅设定的保持电流大小而定),RWBLEED导通,开始拉电流保持可控硅导通,具体工作时序可以参看如下图:四个阶段分析:T1阶段,由于可控硅没有导通,也就是切相阶段,STRONG BLEEDER ON TIME,开始拉电流;T2阶段,由于可控硅导通,TRIAC ON TIME,这个阶段只要回路里面的电流大于设定值,那么STRONG BLEEDER&WEAK BLEEDER是关断的;T3阶段,可控硅仍然导通,但是如果回路里面的电流少于设定值,WEAK BLEEDER ON TIME,继续保持可控硅导通;T4阶段,可控硅导通,但是一旦STRONG BLEEDER侦测到输入电压低于54V,由于WEAK BLEEDER电阻太大(一般为20K以上),那么STRONG BLEEDER(一般为4K以内)开始拉电流,继续保证可控硅导通;2.DAMPER回路设计为什么要用RDAMPER电阻,RDAMPER电阻不仅可以抗击回路开通瞬间的冲击电流,还可以防止回路中CBUFFER电容充电过快而可控硅意外截止,导致不断重启,但是CBUFFER 选取也有要求,必须折中,先参考如下波形图:A.CBUFFER电容太小,会导致开通瞬间电容很快充电,然而后面的PWM还没有建立,直接导致可控硅保持电流不够,从而导致可控硅关断,就出现上面的左边波形,不断关断重启现象;B.CBUFFER电容是不是越大越好呢,不,电容越大,导致电容上存储的能量越多,就会导致下半个切相波形到来之前,CBUFFER电容放电不及时,电容上存在一定电压,从而导致可控硅不能正常切相;所以CBUFFER电容的大小是要根据实际情况而定,由经验值定最佳;那么RDAMPER电阻是不是随意选取呢?不A.大的RDAMPER会导致两个不好的结果-低效率:大电阻导致消耗在电阻上的功率过大,整机效率偏低;-闪烁:大电阻导致回路充电电流过小,保持电流不够,从而产生闪烁;B.小的RDAMPER会导致两个不好的结果-大的冲击电流;-环路的震荡,不断重启,见上图;所以RDAMPER的取值要考虑到功耗和环路的稳定性折中。

It also has application in any system where a wide dynamic range broadband synthesized frequency converter is required.The SL2101 is a single chip solution containing all necessary active circuitry and simply requires an external tuneable resonant network for the local oscillator sustaining network. The pin assignment is contained in Figures 2and 3 for the SSOP and MLP packages and the block diagram in Figure 1.The device also contains a programmable facility to adjust the power in the lna/mixer so allowing power to be traded against intermodulation performance for power critical applications, such as telephony modems.CharacteristicUnitsRF input operating range 50-1400MHz Input noise figure, SSB,50-860 MHz 860-1400 6.5 - 8.58.5 - 12dB dB Conversion gain 12dB CTB (fully loaded matrix)-68dBc CSO (fully loaded matrix)-65dBc P1dB input referred110dB µV Local oscillator phase noise as upconverter SSB @ 10kHz offset SSB @ 100kHz offset -90-112dBc/Hz dBc/Hz Local oscillator phase noise as downconverter SSB @ 10 kHz offset SSB @ 100 kHz offset -93-115dBc/Hz dBc/Hz Local oscillator phase noise floor-136dBc/Hz PLL spurs on converted output with input @ 60dB µV <-70dBc PLL maximum comparison frequency 4 MHz PLL phase noise at phase detector-152dBc/HzConverter SectionIn normal application the RF input is interfaced through appropriate impedance matching and an AGC front end to the device input. The RF input preamplifier of the device is designed for low noise figure, within the operating region of 50 to 1400 MHz and for high intermodulation distortion intercept so offering good signal to noise plus composite distortion spurious performance when loaded with a multi carrier system. The preamplifier also provides gain to the mixer section and back isolation from the local oscillator section.The lna/mixer current and hence signal handling and device power consumption are programmable through the I2C bus as tabulated in Figure 7.The typical RF input impedance and matching network for broadband upconversion are contained in Figures 8 and 9 respectively and for narrow band downconversion in Figures 10 and 11 respectively. The input referred two tone intermodulation test condition spectrum at maximum power setting is shown in Figure 12. The typical input NF and gain versus frequency and NF specification limits, over selectable power settings are contained in Figures 13, 14 and 15 respectively.The output of the preamplifier is fed to the mixer section which is optimized for low radiation application. In this stage the RF signal is mixed with the local oscillator frequency, which is generated by the on-board oscillator. The oscillator block uses an external tuneable network and is optimized for low phase noise. The typical oscillator application as an upconverter is shown in Figure 16 and the typical phase noise performance in Figure 17. The typical oscillator application as a downconverter is shown in Figure 18, and the phase noise performance in Figure 19. This oscillator block interfaces direct with the internal PLL to allow for frequency synthesis of the local oscillator. Finally the output of the mixer provides an open collector differential output drive. The device allows for selection of an IF in the range 30-1400MHz so covering standard HIIFs between 1 and 1.4GHz and all conventional tuner output IFs. When used as a broadband upconverter to a HIIF the output should be differentially loaded, for example with a differential SAW filter, to maximize intermodulation performance. A nominal load in maximum power setting is shown in Figure 4, which will typically be terminated with a differential 200 load. When used as a narrowband downconverter the output should be differentially loaded with a discrete differential to single ended converter as in Figure 5, shown tuned to 44MHz IF. Alternatively loading can be direct into a differential input amplifier or SAWF, in which case external loads to Vcc will be required. An example load for 44MHz application with a gain of 16dB is contained in Figure 6. The NF and gain with recommended load versus power setting are contained in Figure 20. The typical IF output impedance as upconverter and downconverter are contained in Figures 21 and 22 respectively.In all applications care should be taken to achieve symmetric balance to the IF outputs to maximize intermodulation performance.The typical key performance data at 5V Vcc and 25 deg C ambient are shown in the section 'Quick Reference Data'.PLL Frequency SynthesizerThe PLL frequency synthesizer section contains all the elements necessary, with the exception of a reference frequency source and loop filter to control the oscillator, so forming a complete PLL frequency synthesized source. The device allows for operation with a high comparison frequency and is fabricated in high speed logic, which enables the generation of a loop with good phase noise performance.The LO signal from the oscillator drives an internal preamplifier, which provides gain and reverse isolation from the divider signals. The output of the preamplifier interfaces direct with the 15-bit fully programmable divider. The programmable divider is of MN+A architecture, where the dual modulus prescaler is 16/17, the A counter is 4-bits, and the M counter is 11 bits.The output of the programmable divider is fed to the phase comparator where it is compared in both phase and frequency domain with the comparison frequency. This frequency is derived either from the on-board crystal controlled oscillator or from an external reference source. In both cases the reference frequency is divided down tothe comparison frequency by the reference divider which is programmable into 1 of 29 ratios as detailed in figure 23. Typical applications for the crystal oscillator are contained in Figure 24 and Figure 25. Figure 25 is used when driving a second SL2101 as a downconverter.The output of the phase detector feeds a charge pump and loop amplifier, which when used with an external loop filter and high voltage transistor, integrates the current pulses into the varactor line voltage, used for controlling the oscillator.The programmable divider output Fpd divided by two and the reference divider output Fcomp can be switched to port P0 by programming the device into test mode. The test modes are described in Figure 26.The crystal reference frequency can be switched to BUFREF output by bit RE as described in Figure 27. The BUFREF output is not available on the MLP package.ProgrammingThe SL2101 is controlled by an I2C data bus and is compatible with both standard and fast mode formats.Data and Clock are fed in on the SDA and SCL lines respectively as defined by I2C bus format. The device can either accept data (write mode), or send data (read mode). The LSB of the address byte (R/W) sets the device into write mode if it is low, and read mode if it is high. Tables 1 and 2 in Figure 28 illustrate the format of the data. The device can be programmed to respond to several addresses, which enables the use of more than one device in an I2C bus system. Figure 28, Table 3 shows how the address is selected by applying a voltage to the 'ADD' input. When the device receives a valid address byte, it pulls the SDA line low during the acknowledge period, and during following acknowledge periods after further data bytes are received. When the device is programmed into read mode, the controller accepting the data must pull the SDA line low during all status byte acknowledge periods to read another status byte. If the controller fails to pull the SDA line low during this period, the device generates an internal STOP condition, which inhibits further reading.Write ModeWith reference to Figure 28, Table 1, bytes 2 and 3 contain frequency information bits 214 -20 inclusive.Byte 4 controls the synthesizer reference divider ratio, see Figure 23 and the charge pump setting, see Figure 29. Byte 5 controls the test modes, see Figure 26, the buffered crystal reference output select RE, see Figure 27, the power setting, see Figure 7 and the output port P0.After reception and acknowledgement of a correct address (byte 1), the first bit of the following byte determines whether the byte is interpreted as a byte 2 or 4, a logic '0' indicating byte 2, and a logic '1' indicating byte 4. Having interpreted this byte as either byte 2 or 4 the following data byte will be interpreted as byte 3 or 5 respectively. Having received two complete data bytes, additional data bytes can be entered, where byte interpretation follows the same procedure, without re-addressing the device. This procedure continues until a STOP condition is received. The STOP condition can be generated after any data byte, if however it occurs during a byte transmission, the previous byte data is retained. To facilitate smooth fine tuning, the frequency data bytes are only accepted by the device after all 15 bits of frequency data have been received, or after the generation of a STOP condition.Read ModeWhen the device is in read mode, the status byte read from the device takes the form shown in Figure 28, Table 2.Bit 1 (POR) is the power-on reset indicator, and this is set to a logic '1' if the Vcc supply to the device has dropped below 3V (at 25° C), e.g., when the device is initially turned ON. The POR is reset to '0' when the read sequence is terminated by a STOP command. When POR is set high this indicates that the programmed information may have been corrupted and the device reset to the power up condition.Bit 2 (FL) indicates whether the synthesizer is phase locked, a logic '1' is present if the device is locked, and a logic '0' if the device is unlocked.Programmable Features Synthesizer programmable divider Function as described above Reference programmable divider Function as described above.Charge pump current The charge pump current can be programmed by bits C1 & C0 within data byte 4, as defined in Figure 29.Power settingThe device power and hence signal handling can be programmed by bits I2 - I0 within data byte 5, as defined in Figure 7.In all power settings the synthesizer remains enabled to facilitate rapid PLL lock reacquisitionTest modeThe test modes are defined by bits T2 - T0 as described in Figure 26.General purpose ports, P0The general purpose port can be programmed by bits P0;Logic '1' = onLogic '0' = off (high impedance) - this is the default state at device power onBuffered crystal reference output, BUFREFThe buffered crystal reference frequency can be switched to theBUFREF output by bit RE as described in Figure 27. The BUFREF output defaults to the 'ON' condition at device power up. This output is only available on the SSOP package.Figure 4 - Nominal Output Load as Upconverter into Differential SAWF151410nH10nHVccSL2101OUTPUTOUTPUTB200Ω200ΩSAWF33Ω33ΩFigure 5 - Nominal Output Load as Downconverter, 44MHz IFFigure 6 - Output Load as Downconverter to a Differential AmplifierI2I1I0Supply Current in mATyp.Max.00090*12000167890105675011516810082109101597811048641114357Figure 7 - Supply Current* default setting on SL2101OUTPUT15 pF15 pF10 uH820 nH820 nH 10 nF1514SL2101VccOUTPUT1514SL210110 nF10 nFOUTPUTBVcc680 nH680 nH 100 nFFigure 8 - Typical RF Input Impedance as Broadband Upconverter (Maximum Power Setting)Figure 9 - RF Input Impedance Matching Network as 50 - 860MHz Upconverter200Ω100nF100nF47nH910RFINPUT RFINPUTBSL2101RFIN75 Ωsetting)Figure 11 - RF Input Impedance Matching Network as 1.22GHz Downconverter2.7pF10nF3.9nH910RFINPUTRFINPUTBSL2101RFIN200 ΩFigure 12 - Two Tone Intermodulation Test Condition Spectrum, Input ReferredFigure 13 - Input NF, Typical (Maximum Power Setting)48 dBuV 94 dBuVcB d 64-3M I I f2-f1f1-dff2+dff1f2df47 dBuVcB d 74-2M IIFigure 14 - Conversion Gain as Upconverter (Maximum Power Setting)Figure 16 - Upconverter Oscillator ApplicationI2I1I0Typ NF (dB)Gain (dB)typ CSO* (dBc)typ CTB* (dBc)typ IPIP2 (dB µV)typ IPIP3 (dB µV)000 6.810.1-65-65144121001 6.09.1-60-54141114010 5.87.6-56-42132108011 6.5 5.4-49-351291061008.710.4-63-601461171016.210.0-64-56142113110 5.98.3-58-421331061116.45.8-50-34126103Figure 15 - Upconverter Gain, NF and Intermodulation with Recommended Load Versus PowerSetting* Measured with 128 channels at +7dBmV.1 k ΩVaractor lineBB5552 pFBB5553x2.75 mm(centre)3x1.5 mm3x0.5 mmFigure 17 - Oscillator Typical Phase Noise Performance at 10kHz OffsetFigure 18 - Downconverter Oscillator ApplicationFigure 19 - Typical Phase Noise Performance as Downconverter at 10kHz Offset4.3 nH1 k ΩVaractor line2.5 pFBB5552021808284868890929496981001040106010801100112011401160118012002201LO frequency)t e s f f o z H k 01t a (e s i o n e s a h PI2I1I0Typ NF(dB)Gain (dB)typ IPIP3(dBµV)00010.315.61240019.315.11190108.814.01120118.712.110610011.615.4121.31019.015.1119.71108.313.9112.61118.011.9106.3Figure 20 - Downconverter Gain, NF and IP3 with Recommended (Fig. 4) Load Versus PowerFigure 21 - Typical IF Output Impedance as Upconverter, Single-EndedFigure 22 - Typical IF Output Impedance as Downconverter, Single-EndedR4R3R2R1R0Ratio000002000014000108000111600100320010164001101280011125601000Illegal state01001501010100101120011004001101800111016001111320Figure 23 - Reference Division RatiosFigure 24 - Standard Application10000Illegal state1000161001012100112410100481010196101101921011138411000Illegal state110017110101411011281110056111011121111022411111448R4R3R2R1R0RatioXTALCAPXTAL47pf4MHz47pf12Figure 25 - Application When Driving Two SL2101 from One Crystal T2T1T0Test Mode Description000Normal operation001Charge pump sink *Status byte FL set to logic ‘0’010Charge pump source *Status byte FL set to logic ‘0’011Charge pump disabled *Status byte FL set to logic ‘1’100Normal operation and Port P0 = Fpd/2101Charge pump sink *Status byte FL set to logic ‘0’Port P0 = Fcomp110Charge pump source *Status byte FL set to logic ‘0’Port P0 = F comp111Charge pump disabled *Status byte FL set to logic ‘1’Port P0 = F compFigure 26 - Test Modes* clocks need to be present on crystal and local oscillator to enable charge pump test modes and to toggle status byte bit FL.RE BUFREF output0disabled, high impedance1enabledNote:The BUFREF output is only available on the SSOP packageFigure 27 - Buffered Crystal Reference Output SelectFigure 28 - Read/Write Data FormatsTable 1 - Write Data Format (MSB is transmitted first)MSBLSBAddress 11000MA1MA00A Byte 1Programmable divider 02142132122112102928AByte 2Programmable divider 2726252423222120A Byte 3Control data 1C1C0R4R3R2R1R0A Byte 4Control dataT2T1T0I2I1I0REP0AByte 5Table 2 - Read Data Format (MSB is transmitted first)A:Acknowledge bitMA1,MA0:Variable address bits (see Table 3)214-20:Programmable division ratio control bits I2-I0:lna/mixer power select (see Figure 7)C1-C0:Charge pump current select (see Figure 29)R4-R0:Reference division ratio select (see Figure 23)T2-T0:Test mode control bits (see Figure 26)RE :Buffered crystal reference output enable (see Figure 27P0:P0 port output statePOR :Power on reset indicator FL:Phase lock flagMSBLSBAddress 11000MA1MA01A Byte 1Programmable dividerPORFLAByte 2Table 3 - Address Selection MA1MA0Address input voltage level000-0.1Vcc 01Open circuit 100.4Vcc – 0.6 Vcc #110.9 Vcc - VccFigure 29 - Charge Pump CurrentElectrical Characteristics - Test conditions (unless otherwise stated).

在撰写这篇关于SSL证书的文章之前,让我们先来了解一下什么是SSL证书以及它的作用和重要性。

SSL(Secure Sockets Layer)是一种加密技术,用于在网络通信中确保数据传输的安全性。

SSL证书则是对全球信息湾进行加密和身份验证的一种数字证书,它是全球信息湾安全的基石之一。

1. SSL证书的作用和重要性SSL证书通过加密技术,对全球信息湾与用户之间的通信进行加密,保护敏感信息不被第三方窃取。

它还可以验证全球信息湾的真实性,确保用户访问的是合法的全球信息湾而不是恶意仿冒站点。

SSL证书对于全球信息湾安全和用户隐私保护至关重要,尤其是在进行在线交易和数据传输时。

2. 为什么需要SubjectAltName字段在SSL证书中,SubjectAltName(SAN)字段是扩展的一部分,它允许证书持有者在同一个证书中包含多个域名或IP位置区域。

这对于拥有多个域名的全球信息湾和多站点证书非常重要,可以减少证书的数量和管理成本,同时提高了全球信息湾的灵活性和安全性。

3. SAN字段的应用和好处SAN字段的应用范围非常广泛,它可以包含主域名、子域名、IP位置区域甚至是通配符。

对于企业和组织来说,SAN字段可以为不同的子全球信息湾或虚拟主机提供统一的SSL保护,简化了证书的管理和部署。

SAN字段还可以为全球信息湾提供多域名的安全保护,满足了多域名全球信息湾和多站点需求。

4. 个人观点和理解从个人的角度来看,SSL证书的安全性和多功能性是非常重要的。

SAN字段的应用为全球信息湾提供了更加灵活和全面的安全保护,大大提高了全球信息湾的安全性和可信度。

在当前网络安全形势下,采用SSL证书并合理利用SAN字段,对于保护全球信息湾和用户信息至关重要。

总结和回顾在本文中,我们深入探讨了SSL证书及其扩展字段SubjectAltName 的重要作用和应用。

通过对SSL证书的深入理解,我们可以更好地保护全球信息湾安全,提升用户体验,确保网络通信的安全性。

san(subject alternative name)证书

san(subject alternative name)证书

san(subject alternative name)证书在数字证书中,subject alt name(简称为SAN)是指证书主体(即证书持有者)的可选名称。

这种机制允许证书持有者使用多个域名或替代域名来扩展证书的有效域名列表。

这在网络安全的实际应用中具有重要意义,因为这样可以减少因证书混淆或域名覆盖导致的安全风险。

本篇文章将介绍san证书的基本概念、应用场景和操作步骤。

一、什么是SAN证书?SAN证书是一种数字证书,其中包含额外的域名信息,用于扩展证书的主题名称(Subject Name)。

传统的证书主题名称是唯一的,用于标识证书持有者。

而SAN证书则允许在主题名称之外添加多个替代域名,提高了证书的灵活性和安全性。

二、SAN证书的应用场景1. 多域名站点:一个实体拥有多个域名,需要为每个域名配置独立的SSL证书。

SAN证书可以解决因使用单个证书而覆盖其他域名的风险,确保每个域名都得到保护。

2. 临时替换域名:在临时情况下,一个实体可能需要访问另一个域名的资源,例如在测试或应急响应期间。

SAN证书允许使用替代域名进行临时访问,而无需更换整个证书。

3. 证书混淆防护:通过使用SAN证书,可以减少因混淆攻击而导致其他域名被覆盖的风险。

这种攻击试图将恶意代码插入正常的SSL 证书中,以窃取敏感数据或执行其他恶意操作。

通过使用SAN证书,可以减少这种攻击的潜在目标。

三、SAN证书的操作步骤1. 申请SSL证书:首先,需要向可信的SSL证书提供商申请常规的或SAN证书。

确保选择支持SAN机制的证书类型。

2. 提交域名列表:在申请过程中,需要提交要保护的替代域名的列表。

这可以包括实际的域名、测试域名或其他临时替换的域名。

3. 验证域名所有权:证书颁发机构(CA)可能会要求验证替代域名的所有权,以确保它们属于申请者。

这可以通过提供DNS记录或通过电子邮件确认来完成。

4. 安装和管理证书:一旦获得SAN证书,需要将其安装到服务器上,并确保服务器能够正确管理和更新证书。

8.1 Start-up and UnderVoltage LockOut (UVLO)
Initially, the IC is self-supplying from the rectified mains voltage. The IC starts switching as soon as the voltage on pin VCC passes the VCC(startup) level. The supply can be taken over by the auxiliary winding of the transformer as soon as VCC is high enough and the supply from the line is stopped for high efficiency operation. Alternatively the IC can be supplied via a bleeder resistor connected to a high voltage. Note however the maximum VCC voltage rating of the IC. If for some reason the auxiliary supply is not sufficient, the high-voltage supply can also supply the IC. As soon as the voltage on pin VCC drops below the VCC(UVLO) level, the IC stops switching and will restart from the rectified mains voltage, if the internal current delivered is sufficient.
