QX5305【指导书】关于尽量避免使用QX5305的EN引脚做PWM调光的说明 20140509

QX5305【指导书】关于尽量避免使用QX5305的EN引脚做PWM调光的说明 20140509

关于尽量避免使用QX5305的EN引脚做PWM调光的说明QX5305的EN引脚是具备一个传统的使能芯片工作和关闭的功能。

我们可以使用该引脚做低速的开关控制,譬如爆闪,SOS等,但如果用于PWM高速调光(譬如超过100Hz的频率),那么,就需要充分了解PWM调光在EN使能控制上的弱点。

一一 QX5305的DRV开启和关闭是跟随EN引脚的,但可能存在延时。

一一 PWM高速调光时,在EN=LOW的时候,电感能量还得释放。

由于存在延时,因此,我们来看整一个调光周期,假定DRV驱动频率Fdrv=200kHz,PWM调光频率Fpw m=200Hz,占空比50%。

1.PWM 开始,一个周期为5ms ,占空比50%,2.5ms 高电平,2.5ms 低电平。

当Rfb 的电压Vfb 》0.2V 时,Toff 固定时间关断序列启动,DRV 开始输出低电平,关断MOS.因此,从下图可以看出,在整个EN=HIGH 的2.5ms 中,DRV 引脚都是一个开关信号,开启MOS ,对电感充电; 关闭MOS ,环路电动势提升,电感放电,使得输出电流恒定在预设水平。

但是,由于DC/DCBOOST的电路架构,使得高速调整EN来实现线性调光并不现实。

这是因为,一旦EN=LOW时,DRV会立即关断,因此,MOS会立即被关闭。

而电路很可能会遇到这样一个情况:上图是对于DC/DCBOOST架构进行高速EN调整时所出现的情形。

因此,使用PWM来控制EN引脚调光是难以达到线性的调光效果,如下图:输出电流与占空比的关系可能呈现出:非线性的n型曲线。

因此,我们建议使用QX5305的EN使能,着重强调开启和关闭整机系统这个功能,而不是进行高速调光。

即使是调光,也最好只应用在低速率的,如爆闪,SOS效果等。

QX5305采用固定off-t ime 控制工作方式,其工作频率可高达2.5MHz ,可使外部电感和滤波电容、体积减少,效率提高。

在DIM 脚加PWM 信号,可调节LED 灯的亮度。

通过调节外置的电阻,能控制高亮度LED 灯的驱动电流,使LED 灯亮度达到预期恒定亮度,流过高亮度LED 灯的电流可从几毫安到2安培变化。

片内的R-S触发器分别由off-time定时器置位和CS比较器、FB比较复位,它控制外部MOSFET管并和功率电感L、LED、肖特基二极管共同构成一个自振荡的,连续电感电流模式的升压型恒流LED驱动电路(参见图1)。

除了固定off-time控制这点外,QX5305的工作方式和普通的电流模式PWM控制型DC/DC升压电路非常相似。

当工作在连续电流模式下时,流过功率电感的电流I L如图2所示。

V DD上电时,off-time定时器的输出置位内部触发器使输出为高,驱动外部了功率MOSFET导通,T ON周期开始。

这时候,流过功率电感L的初始电流为零,电流以上升的模式从V IN通过功率电感L,MOSFET和电流采样电阻R CS流到地。

该电流将一部分能量储存在功率电感里并在R CS 上产生一个压降V CS。

与此同时输出滤波电容对LED放电,该电流在R FB上产生一个压降V FB,V FB被误差放大器放大。

当电流上升到使得V CS > 260mV或V FB > 误差放大器的输出电压时,CS 或FB比较器的输出复位内部触发器使得输出变低,控制外部功率MOSFET关断,T ON周期结束,T OFF周期开始。

T OFF周期内,储存在功率电感里的能量以反电势的形式与VIN叠加后,通过肖特基二极管、LED、电流反馈电阻R FB构成回路,电流呈下降的模式,与此同时输出滤波电容被充电。

当预先设置的T OFF时间间隔到达时,off-time定时器的输出再次置位内部触发器使得输出为高,外部功率MOSFET重新导通,T OFF周期结束,开始新的T ON周期,电流再次以上升的模式流通,同时输出电容对LED放电……。

依次循环往复,使LED上的电流得以连续而且保持稳定。

正常工作情况下,电感电流上升、下降的斜率与V IN、功率电感L的感值和LED的正向压降相关。

V CS间接反映了电感的峰值电流,也代表了峰值功率,而V FB间接反映了输出电流的大小。

QX5305根据V FB来不断调节外部功率MOSFET管导通的时间T ON,即输出电流的脉冲宽度(也就是输入到功率电感L中的能量增加,导致流过负载的输出电流变大,反之则反。

如此闭环调节使得输出电流能够得到恒定。

应用指引1)L ED 电流的设定LED的电流由R FB设定,R F B阻值不同,就可以设置不同的LED驱动电流。

R F B 的估算公式如下:R F B=260mV/I OI O为驱动LED灯的电流。

2)峰值功率的限定限定峰值功率可以减小上电时的冲击电流,并且在电路异常时可以起到保护作用。

峰值功率由R C S设定,R C S的计算公式如下:R C S=260mV/Io*K K=0.7*V I N/V O也即:R C S=R FB*0.7*V I N/V OI O为驱动LED灯的电流;V O为输出电压,即所有串联LED正向电压的总和。

3)工作频率的确定QX5305采用固定o ff-t ime控制工作方式,其工作频率为F=1/(T O F F+T O N)其中T O N时间与功率电感的感值和输入输出的电压差相关,而T O FF的off-t ime 时间由片内的off-t ime 定时器和片外的T O F F管脚的R O FF、C O F F决定。

因此可通过外部电阻和电容设置最小T O F F时间,从而间接设定工作频率,其中点空比约为D≈(V O UT-V I N)/V O UT,而T O F F计算公式如下:这里100KΩ电阻和12pF电容是芯片内部集成的参数,当T OF F管脚悬空时:在T O FF管脚上单独接R O F F电阻可以提搞工作频率,而单独接C O FF则可以降低工作频率。

例如:当T O FF脚接470pF电容时,T O F F≈24.6uS,如果D=0.1,则电路工作频率F约为36.6KHz。

工作频率的高低,是要根据实际使用情况来决定的。

工作频率高,功率电感的数值可以越小,电感的体积也越小,同时也有利于选用低容值小体积的输入输出滤波电容。

但是较高的工作频率会导致MOSFET管和肖特基二极管的开关损耗增加,发热加剧,导致电路的效率下降。

这点在高输出电压下工作时较为明显。

因此,如果在高于80V的工作条件下,建议QX5305的工作频率不宜超过80KHz。

4)功率电感L选择功率电感L的选用原则,一是确保流过LED的电流是连续的并且纹波电流ΔI 值远小于流过LED的电流值,其次是保证其工作时不会出现磁饱和现象。

QX5305电路在工作时,输入电源在MOSFET管导通T O N期间直接对功率电感提供能量,其于时间则由电源与功率电感内储存的能量来维持LED电流。

换句话说,功率电感在MOSFET管导通时储能,MOSFET管关闭时释放能量,电感及LED上的电流方向始终是不变的。

功率电感的充放电在输出电流上形成锯齿状纹波电流(见图2)。

纹波电流(ΔI=I M A X-I LI N)的上升下降斜率及幅值直接与电感上的电压和电感量相关,其关系如下式:T O N时:V L=V I N-V D P-V C S;T O F F时:V L=-V I N+LED+V F纹波电流ΔI的大小与功率电感的电感量成反比例,当纹波电流过大时,将导致输出电流的断续(此时可以理解为:T O N时功率电感内储存的能量不足以在T O F F 时释放来维持负载电流)。

因而,一定的工作电压、负载下,不同的电感元件参数,流过负载的电流会出现连续模式和非连续两种模式。

在驱动LED的情况下,为保持LED电流的恒定,不希望出现非连续模式。

因此,在工作电压、负载一定的情况下,必须合理地选择功率电感数值以保证电路工作于连续模式下。

当功率电感的电感量足够大时,一般可保证电流不会出现非连续模式。

同时较大的电感量也使得流过负载的电流脉动分量较小,有利于延长LED的寿命。

通常可根据以下公式估算出保证连续模式工作的最小电感量,然后在条件许可的情况下,尽可能地采用较大的电感量值。

在off-t ime期,流过LED灯的ΔI L计算如下:为了使流过LED灯电流波动小于ΔI L,电感值应满足:T O F F在上一节中由R O F F和C O F F来设定,ΔI L可取I L的十分之一。

通常,当输入、输出电压的压差较大或者输出功率较大时,需要加大功率电感的值,反之,可以用较小的功率电感值。

一般取值约在几百微亨到十几毫亨,视实际应用而定。

另外不可忽视的一个问题是,QX5305工作时流过功率电感的峰值电流通常可高达安培级以上,所选用的功率电感必须具有足够的DC 工作电流容量,否则电感会发生磁饱和,造成电路的效率大大下降,甚至电路不能正常稳定工作。

一般情况下,要求功率电感的饱和电流必须大于最大输出电流的 1.5倍以上。

同时在大电流条件下功率电感本身的内阻(ESR)也不可忽视,它会极大地影响转换效率。

所以,在确定了电感量以后,如果希望提高QX5305驱动器的工作效率,在体积允许的情况下,可选用较大的磁性元件及较粗的导线绕制的功率电感。

5)MOSFET 管的选用首先要考虑MOSFET的耐压,一般要求MOSFET的耐压高于最大输出的电压 1.5倍以上。

其次,根据驱动LED灯电流的大小,选择MOSFET的I最大电流。

一般情D S最大电流是LED灯驱动电流的3倍以上。

另外MOSFET 况下,应选用MOSFET的ID S越小,在MOSFET管上面的功率越小,电路的工作效率就越的内阻要尽可能小;RD S高。

另外,高电压应用时,由于高耐压的MOSFET管完全导通所需的驱动电压V G S也比较高(可能会高于QX5305的输出驱动电平),为此应该选择V G S低于5V的型号。

6)EN使能端在EN端接(低电平)地时,QX5305处于休眠状态,此时,工作电流小于10uA,自耗电非常小,当EN端为高电平时,QX5305处于工作状态,此时空载工作电流约为200uA。

7)LED灯亮度调节LED灯的亮度调节,可由以下二种方法:第一种方法是模拟调光,通过改变R FB的电阻。
