voltage references that are specifically designed for excellent initial voltage accuracy and The REF50xx family of voltage references features drift.Figure 21shows a simplified block diagram of extremely low dropout voltage.With the exception of the REF50xx.the REF5020,which has a minimum supply requirement of 2.7V,these references can be operated with a supply of 200mV above the output voltage in an unloaded condition.For loaded conditions,a typical dropout voltage versus load plot is shown in Figure 6of the Typical Characteristics.The REF50xx provides a very accurate voltage output.However,V OUT can be adjusted from the nominal value for the purpose of trimming system errors by configuring the TRIM pin (pin 5).The TRIM pin provides for adjustment of the voltage at V OUT over a ±15mV range.Figure 23shows a typical circuit using the TRIM pin to adjust V OUT .When using this technique,the temperature coefficients of the resistors can degrade the temperature drift at the output.Figure 21.REF50xx Simplified Block DiagramFigure 22shows the typical connections for the REF50xx.A supply bypass capacitor ranging between 1μF to 10μF is recommended.A 1μF to 50μF,low-ESR output capacitor (C L )must be connected to V OUT .Figure 23.V OUT Adjustment Using the TRIM PinThe REF50xx is designed for minimal drift error,which is defined as the change in output voltage over temperature.The drift is calculated using the box method,as described by the following equation:Figure 22.Basic ConnectionsThe REF50xx features a maximum drift coefficient of 3ppm/°C for the high-grade version,and 8ppm/°C for the standard-grade.TEMPERATURE MONITORINGPOWER DISSIPATIONNOISE PERFORMANCEREF5020,,REF5025REF5030,REF5040REF5045,REF5050SBOS410–JUNE 2007The temperature output

contains all of the features needed to implement Push-Pull and Bridge topolo-gies,using current-mode control in a small10pin package. Features included are,startup regulator,dual mode current limit,dual alternating gate drivers,thermal shutdown,soft-start and slope compensation.This high speed IC has total propagation delays<100nS.The Functional Block Diagram of the LM5030is shown in Figure1.The LM5030is designed for Current-Mode Control convert-ers which require alternating outputs,such as Push-Pull and Half/Full Bridge topologies.The features included in the LM5030enable all of the advantages of Current-Mode Con-trol,line feed-forward,cycle by cycle current limit and sim-plified loop compensation.The oscillator ramp is internally buffered and added to the PWM comparator input to provide slope compensation necessary for current mode control at higher duty cycles.High Voltage Start-Up RegulatorThe LM5030contains an internal high voltage startup regu-lator.The input pin(Vin)can be connected directly to line voltages as high as100V.The regulator output is internally current limited to10mA.Upon power up,the regulator is enabled and sources current into an external capacitor con-nected to the V CC pin.The recommended capacitance range for the V CC regulator is0.1µF to50µF.When the voltage on the V CC pin reaches the regulation point of7.7V,the control-ler outputs are enabled.The outputs will remain enabled unless,V CC falls below6.1V or if the SS/SHUTDOWN pin is pulled to ground or an over temperature condition occurs.In typical applications,an auxiliary transformer winding is diode connected to the V CC pin.This winding raises the V CC voltage greater than8V,effectively shutting off the internal startup regulator and saving power while reducing the con-troller dissipation.The external V CC capacitor must be sized such that the self-bias will maintain a V CC voltage greater than6.1V during the initial start-up.During a fault mode when the converter self bias winding is inactive,external current draw on the V CC line should be limited as to not exceed the maximum power dissipation of the controller.An external start-up or other bias rail can be used instead of the internal start-up regulator by connecting the V CC and the Vin pins and feeding the external bias voltage(8-15V)to that node.Error AmplifierAn internal high gain error amplifier is provided within theLM5030.The amplifier’s non-inverting reference is tied to1.25V.In non-isolated applications the power converter out-put is connected to the VFB pin via the voltage settingresistors and loop compensation is connected between theCOMP and VFB pins.For most isolated applications the error amplifier function isimplemented on the secondary side ground.Since the inter-nal error amplifier is configured as an open drain output itcan be disabled by connecting VFB to ground.The internal5K pull-up resistor,connected between the5V reference andCOMP,can be used as the pull-up for an optocoupler orother isolation device.PWM ComparatorThe PWM comparator compares the compensated currentramp signal to the loop error voltage from the internal erroramplifier(COMP pin).This comparator is optimized forspeed in order to achieve minimum discernable duty cycles.The comparator polarity is such that zero Volts on the COMPpin will cause a zero duty cycle.Current Limit/Current SenseThe LM5030contains two levels of over-current protection.Ifthe voltage on the current sense comparator exceeds0.5Volts the present cycle is terminated(cycle by cycle currentlimit).If the voltage on the current sense comparator ex-ceeds0.625Volts,the controller will terminate the presentcycle and discharge the softstart capacitor.A small RC filter,located near the controller,is recommended for the CS pin.An internal MOSFET discharges the current sense filtercapacitor at the conclusion of every cycle,to improve dy-namic performance.The LM5030CS and PWM comparators are very fast,andas such will respond to short duration noise youtconsiderations are critical for the current sense filter andsense resistor.The capacitor associated with the CS filtermust be placed very close to the device and connecteddirectly to the pins of the IC(CS and RTN).Also if a currentsense transformer is used,both leads of the transformersecondary should be routed to the sense resistor,whichshould also be located close to the IC.If a current senseresistor located in the drive transistor sources is used,forcurrent sense,a low inductance resistor should be chosen.LM50307Current Limit/Current Sense(Continued)In this case all of the noise sensitive low power grounds should be commoned together around the IC and then a single connection should be made to the power ground (sense resistor ground point).The second level threshold is intended to protect the power converter by initiating a low duty cycle hiccup mode when abnormally high,fast rising currents occur.During excessive loading,the first level threshold will always be reached and the output characteristic of the converter will be that of a current source but this sustained current level can cause excessive temperatures in the power train especially the output rectifiers.If the second level threshold is reached,the softstart capacitor will be fully discharged,a retry will com-mence following the discharge detection.The second level threshold will only be reached when a high dV/dt is present at the current sense pin.The signal must be fast enough to reach the second level threshold before the first threshold detector turns off the driver.This can usually happen for a saturated power inductor or shorted load.Excessive filtering on the CS pin,extremely low value current sense resistor or an inductor that does not saturate with excessive loading may prevent the second level threshold from ever being reached.Oscillator,Shutdown and Sync CapabilityThe LM5030oscillator is set by a single external resistor connected between the RT pin and return.To set a desired oscillator frequency the necessary RT resistor can be calcu-lated as:Each output switches at half the oscillator frequency in a Push-Pull configuration.The LM5030can also be synchro-nized to an external clock.The external clock must be of higher frequency than the free running frequency set by the RT resistor.The clock signal should be capacitively coupled into the RT pin with a 100pF capacitor.A peak voltage level greater than 3Volts with respect to ground is required for detection of the sync pulse.The sync pulse width should be set in the 15to 150nS range by the external components.The RT resistor is always required,whether the oscillator is free running or externally synchronized.The voltage at the RT pin is internally regulated to a nominal 2Volts.The RT resistor should be located very close to the device and connected directly to the pins of the IC (RT and GND).Slope CompensationThe PWM comparator compares the current sense signal to the voltage derived from the COMP pin.The COMP voltage is set by either the internal error amplifier or an external error amplifier through an optocoupler.At duty cycles greater than 50%(composite of alternating outputs)current mode control circuits are prone to subharmonic oscillation.By adding an additional ramp signal to the current sense ramp signal this condition can be avoided.The LM5030integrates this slope compensation by buffering the internal oscillator ramp and summing it internally to the current sense (CS)signal.Addi-tional slope compensation may be added by increasing the source impedance of the current sense signal.Soft Start/ShutdownThe softstart feature allows the converter to gradually reach the initial steady state operating point,thus reducing start-up stresses and surges.An internal 10uA current source and an external capacitor generate a ramping voltage signal which limits the error amplifier output during start-up.In the event of a second level current limit fault,the softstart capacitor will be fully discharged which disables the output drivers.When the fault condition is no longer present,the softstart capaci-tor is released to ramp and gradually restart the converter.The SS pin can also be used to disable the controller.If the SS pin voltage is pulled down below 0.45V (nominal)the controller will disable the outputs and enter a low power state.OUT1,OUT2and Time DelayThe LM5030provides two alternating outputs,OUT1and OUT2.The internal gate drivers can each sink 1.5A peak each.The maximum duty cycle for each output is inherently limited to less than 50%.The typical deadtime between the falling edge of one gate driver output and the rising edge of the other gate driver output is 135ns.Thermal ProtectionInternal Thermal Shutdown circuitry is provided to protect the integrated circuit in the event the excessive junction tem-perature.When activated,typically at 165degrees Celsius,the controller is forced into a low power reset state,disabling the output drivers and the bias regulator.This feature is provided to prevent catastrophic failures from accidental device overheating.L M 5030 8T y p i c a l A p p l i c a t i o n C i r c u i tT y p i c a l A p p l i c a t i o n C i r c u i t ,36V -75V I N a n d 3.3V ,10A O U

产品说明
MBI5030是专为LED全彩显示面板的应用设计的驱动IC，内建可选择16位或是12位灰阶控制的脉波宽度调变功能。 MBI5030 内建16位位移缓存器可以将串行的输入资料转换成每个输出通道的灰阶像数。而且，MBI5030的16个恒流 输出通道所输出的电流值不受输出端负载电压影响并提供一致并且恒定的输出电流。MBI5030的使用者可以经由选用 不同阻值的外接电阻来调整MBI5030各输出级的电流大小。除此之外，MBI5030的使用者还可以藉由可程序化的8位 电流增益调整来调整整体LED的驱动电流。 藉由Scrambled-PWM (S-PWMTM) 的技术，MBI5030可加强脉波宽度调变的功能，并将导通的时间分散成数个较短的 导通时间，进而增加了视觉的更新率。在建立16位灰阶应用的全彩显示面板时，可藉由S-PWM™ 来减少画面的闪烁。 除此之外，MBI5030可降低对于控制器对于脉波宽度调变时钟频率的要求，使用者只需数兆赫的时间频率来达到16位 的灰阶脉波宽度调变。MBI5030可以藉由输入的影像数据来调整相对应LED的亮度。而且，MBI5030可以使每个输出 通道表现出16位(65,536灰阶)的颜色变化。此外，MBI5030可以藉由16位影像数据中用来补偿gamma修正或是LED偏 差的信息来调整每一颗LED明亮度。
