介绍
此评估板用来演示降压型电流调节器LM3409HV PFET 控制器。此设计是在直流输入电压48V时可驱动12个LED (VO=42V),LED的最大平均电流为1.5A。典型的开关频率 为400KHz,但开关频率在整个工作范围内会发生变化。此 电路可接受6~75V输入电压,但如果输入电压低于LED串电 压,变换器就会进入低压降工作模式,理想情况下VO=VIN。
1. 标称开关频率
假定C7=470pF,η=0.97,可得R6:
由步骤2可得L1:
3. LED 平均电流
计算IL-MAX: 假定VADJ=1.24V,可得R9: 最接近此值,精度为1%的电阻为0.15Ω,因此ILED为:
由步骤3可得:
最接近此阻值,精度为1%的电阻为16.5 kΩ,因此实际 tOFF与目标fSW为:
上拉电阻,如果低于5V的PWM信号加在PWM2上,R3确保 CMOS门极被上拉到5V。旁路电容C5选择0.1µF。
方法#3:去掉端子J1上的跳线,使用EN引脚进行内部 PWM调光。外部PWM信号加在EN端可以提供PWM调光。
典型波形图部分列出使用两种PWM调光时的典型LED电 流波形。

(6)软轴及气管走向与固定
2012年培训教材
轻卡系列车型使用的软轴最小转弯半径为200mm,因此
在固定软轴时要避免软轴直径小于200mm。软轴使用扎带固 定,避免和其他运动部件磨碰、干涉,尽可能远离排气管。 装HW50508C变速器时气管顺着软轴进入驾驶室,和软轴捆绑 在一起。

电流检测最的三个最基础知识点电子教案
电流检测最的三个最基础知识点目前,电流检测的阻值非常低,其主要用于测量流经其山的电流。
通过该电阻的电流主要是通过电阻两端的电压反映出来,所以通过应用公式I=V/R该公式是由某著名学校的老师乔治·西蒙·欧姆提出的:即电阻上的电流与电压成正比。
上面简单的介绍就当作抛砖引玉了,本文的主题——电阻选择、高边或低边监测以及检测放大器的选择——都是以这个电气工程基本公式为基础的。
电流检测监控有助于提高一些系统的效率,减少损失。
例如,许多手机实现了电流检测监控,提高电池寿命,同时提高可靠性。
如果电流消耗太大,手机可以做出决定,降低CPU频率来减少电池负载以此延长电池寿命,同时防止手机过热来增加稳定性。
甚至有手机应用程序可以访问电流检测并且对优化手机的性能做出决策。
除了电流检测监控使用了一个电阻,另外两个不太常用的方法也使用了电阻。
其一是使用霍尔效应传感器来测量产生通量场的电流。
虽然这是非侵入性的,并且具有非插入损耗的优点。
它相对来说有点贵,并且要求一个相对大的PCB基板。
另一种方法,使用变压器测量感应的交流电流,也属于面积和成本密集型;并且同时只对交流电流有用。
本文将介绍使用一个电阻进行电流检测监控的三个基本方面:1、选择一个低阻值精度采样电阻。
如果说基板是基于“位置,位置,位置”,然而选择一个电阻就是基于“精度,精度,精度”原则。
2、选择一个检测放大器芯片。
当感应到在小于1欧姆电阻,电压很小的变化也会产生一个很大的结果。
检测放大器将电压变化放大,使无意义的事情变的更有意义。
3、检测电阻的“位置,位置,位置”。
这个若检测参考电源,称为高边检测,或者如果连接地,又叫作低边检测。
精密电流传感应用程序不再是自制食物电路;制造商已经做了所有的研究和现代设计的大部分工作。
电阻选择选择电阻值,精度和物理尺寸都取决于预期的电流测量值。
电阻值越大,测量可能就越精确,但大的电阻值也会导致更大的电流损失。
对于低功率电池驱动的设备,必须减少损失,电阻大约一毫米的长度值并且带有成百上千欧姆的电阻经常被使用。

An internal charge pump guarantees at least 10V of gate drive. The slope of the voltage rise or fall at the GATE is set by an external capacitor connected between GATE and GND, and the 10µA charge pump output cur-rent. When the circuit breaker trips, the undervoltage lockout circuit monitoring V CC trips, or the ON pin is pulled low for more than 40µs, the GATE pin is immediately pulled to GND.SENSE (Pin 7) : Circuit Breaker Set Pin. With a sense resistor placed in the supply path between V CC and SENSE,the circuit breaker will trip when the voltage across the resistor exceeds 50mV for more than 10µs. If the circuit breaker trip current is set to twice the normal operating current, only 25mV is dropped across the sense resistor during normal operation. To disable the circuit breaker,V CC and SENSE can be shorted together.V CC (Pin 8): The positive supply input, ranging from 2.7V to 13.2V for normal operation. I CC is typically 0.6mA. An undervoltage lockout circuit disables the chip until the voltage at V CC is greater than 2.47V.FBRESETGNDV SENSEGATE TIMER1422 BDONBLOCK DIAGRAWLTC142278LTC1422APPLICATIO S I FOR ATIO W UU U V OUTTIMER RESETV2V2V2V1V11.232V1.232V12341422 F04Figure 4. Supply Monitor WaveformsWhen the voltage at the FB pin rises above its reset threshold (1.232V), the comparator COMP 2 output goeshigh, and a timing cycle starts (Figure 4, time points 1 and 4). After a complete timing cycle, RESET is pulled high.The 12µA pull-up current source to V CC on RESET has a series diode so the pin can be pulled above V CC by an external pull-up resistor without forcing current back into supply.When the supply voltage at the FB pin drops below its reset threshold, the comparator Comp 2 output goes low. After passing through a glitch filter, RESET is pulled low (time point 2). If the FB pin rises above the reset threshold for less than a timing cycle, the RESET output will remain low (time point 3).Glitch FilterThe LTC1422 has a glitch filter to prevent RESET from generating a system reset when there are transients on the FB pin . The filter is 20µs for large transients (greater than 150mV) and up to 80µs for small transients. The relation-ship between glitch filter time and the transient voltage is shown in Typical Performance curve: Glitch Filter Time vs Feedback Transient.Soft ResetIn some cases a system reset is desired without a power down. The ON pin can signal the RESET pin to go low without turning off the external N-channel (a soft reset).This is accomplished by holding the ON pin low for only 15µs or less (Figure 5, time point 1). At about 30µs from the falling edge of the ON pin (time point 2) the RESET pin goes low and stays low for one timing cycle.Figure 5. Soft Reset Waveforms1422 F05If the ON pin is held low for longer than 40µs, the gate will turn off and the RESET pin will eventually go low (time points 4, 5 and 6).TimerThe system timing for the LTC1422 is generated by the circuitry shown in Figure 6. The timer is used to set the turn-on delay after the ON pin goes high and the delay before the RESET pin goes high after the output supply voltage is good as sensed by the FB pin.OUT LOADFigure 6.

ON Pin Circuitryand C3 are used to set the rise and fall delays on the 5V supply. Next, the 3.3V supply ramps up with a 20ms delay set by R6 and C2. On the falling edge, the 3.3V supply ramps down first because R6 is bypassed by the diode ing the LTC1422 as a Linear RegulatorThe LTC1422 can be used to Hot Swap the primary supply and generate a secondary low dropout regulated supply.Figure 11 shows how to switch a 5V supply and create a 3.3V supply using the reset comparator and one addi-tional transistor. The FB pin is used to monitor the 3.3V output. When the voltage on the gate of Q2 increases, the 3.3V increases. At the 3.3V threshold, the reset compara-tor will trip. The RESET pin goes high which turns on Q3.This lowers the voltage on the gate of Q2. This feedback loop is compensated by the capacitor C1 and the resistors R6 and R7.Hot Swapping 48V DC/DC Module with Active Low On/Off Control SignalUsing a 7.5V Zener and a resistor, the LTC1422 can switch supplies much greater than the 12V V CC pin rating. As shown in Figure 12, the switching FET Q1 is connected as a common source driver rather than the usual source follower used in previous applications. This allows the ground of the LTC1422 to sit at the negative terminal of the 48V input. The clamp circuit of R5 and D1 provides power to the LTC1422. The resistive divider R1 and R2 at the ON pin monitors the input supply. The switching FET Q1 is prevented from turning on until the input supply is at least 38V. Using the reset comparator to monitor the gate voltage allows the module to be turned on after the gate has reached a minimum level plus one timing cycle.

Switching 48V with Current SensingCurrent Sensing with 48V ApplicationsIn the LTC1422, the SENSE pin threshold is 50mV below the V CC pin. Typically, the current sense resistor is con-nected to the V CC pin, but in 48V applications the sense resistor is connected to the negative terminal of the 48V supply. The circuit in Figure 17 translates the current in the sense resistor to a resistor connected to the LTC1422SENSE pin.The voltage drop across the current sense resistor R SENSE is proportional to the load current I LOAD . The voltage drop across R SENSE is buffered by the op amp follower and is forced on R MIRROR .The mirror current can be described as: I MIRROR = I LOAD •R SENSE /R MIRROR . The mirror current flows through the trip resistor R TRIP . When the mirror current generates 50mV across R TRIP , the LTC1422 will latch the GATE pin low (50mV = I MIRROR • R TRIP = I LOAD • R SENSE /R MIRROR •R TRIP ). This example uses a 48V input but this translation circuit can be used anywhere the current sense resistor is not tied to V CC .Linear Technology Corporation1630 McCarthy Blvd., Milpitas, CA 95035-7417(408) 432-1900 q FAX: (408) 434-0507 q 。
