This makes it well suited to a wide range of industrial and power supply monitoring applications that require the interface to 5V systems while sensing much higher voltages.To allow this its V CC pin can be used independently of S+.Figure 1 shows the basic configuration of the ZXCT1080.Figure 1Typical configuration of ZXCT1080Load current from the input is drawn through R SENSE developing a voltage V SENSE across the inputs of the ZXCT1080.The internal amplifier forces V SENSE across internal resistance R GT causing a current to flow through MOSFET M1. This current is then converted to a voltage by R G . A ratio of 10:1 between R G and R GT creates the fixed gain of 10. The output is then buffered by the unity gain buffer.The gain equation of the ZXCT1080 is:The maximum recommended differential input voltage, V SENSE , is 150mV; it will howeverwithstand voltages up to 800m ⍀. This can be increased further by the inclusion of a resistor, R LIM ,between S- pin and the load; typical value is of the order of 10k .V OUT I L R SENSE R GRGT---------1×I L R SENSE ×10×==https://Figure 2Protection/error sources for ZXCT1080Capacitor C D provides high frequency transient decoupling when used with R LIM ; typical values are of the order 10pFFor best performance R SENSE should be connected as close to the S+ (and SE NSE ) pins;minimizing any series resistance with R SENSE .When choosing appropriate values for R SENSE a compromise must be reached between in-line signal loss (including potential power dissipation effects) and small signal accuracy.Higher values for R SENSE gives better accuracy at low load currents by reducing the inaccuracies due to internal offsets. For best operation the ZXCT1080 has been designed to operate with V SENSE of the order of 50mV to 150mV.Current monitors' basic configuration is that of a unipolar voltage to current to voltage converter powered from a single supply rail. The internal amplifier at the heart of the current monitor may well have a bipolar offset voltage but the output cannot go negative; this results in current monitors saturating at very low sense voltages.As a result of this phenomenon the ZXCT1080 has been specified to operate in a linear manner over a V SENSE range of 10mV to 150mV range, however it will still be monotonic down to VSENSE of 0V.It is for this very reason that Zetex has specified an input offset voltage (V O(10)) at 10mV. The output voltage for any V SENSE voltage from 10mV to 150mV can be calculated as follows:Alternatively the load current can be expressed as:V OUT V SENSE ()xG V O 10()+=I L V OUT V O 10()–()GxR SENSE------------------------------------------=https://Package details - SOT23-5Note: Controlling dimensions are in millimeters.

Functional operation of the device over a -40°C to +85°C temperature range is guaranteed by design, characterization and process control.(2) Nominal 'on' time (T ONnom ) is defined by the input voltage (V IN ), coil inductance (L) and peak current (I LXpkdc ) according to the expression:T ONnom = {I LX(pkdc ) x L/V IN } +200ns.(3) When using the open circuit protection feature, the maximum output voltage under normal operation should be maintained below the minimum value specified, in order to prevent possible disturbance of the current control loop.(4) This is the time for which the device remains active after the EN pin has been asserted low. This delay is necessary to allow the output to be maintained during dc PWM mode operation.(5)The minimum PWM signal frequency during this mode of operation is to ensure that the device remains active during PWM control. This provides a continuous dc output current. For lower frequencies, the device will be gated 'on' and 'off' during PWM control.(6)The maximum PWM signal frequency during this mode of operation should be kept as low as possible to minimize errors due to the turn-off delay of the device (see Enable pin turn-off delay).ZXLD1100S E M I C O N D U C T O R SISSUE 4 - JULY 20044BLOCK DIAGRAMPIN DESCRIPTIONDEVICE DESCRIPTIONThe device is a PFM flyback dc-dc boost converter, working in discontinuous mode.With reference to the chip block diagram and typical application circuit,the operation of the device is as follows:Control loopWhen'EN'is high,the control circuits become active and the low side of the coil(L1)is switched to ground via NDMOS transistor(MN).The current in L1is allowed to build up to an internally defined level (nominally320mA)before MN is turned off.The energy stored in L1is then transferred to the output capacitor (C2)via schottky diode(D1).When the voltage on C2 has risen above the threshold voltage of the series connected LEDs,current will flow through external sense resistor R1.The voltage developed across R1is sensed at pin'FB'and compared to a100mV reference voltage(V REF).A comparator senses when the feedback voltage is above V REF and its output is used to control the'off'time of the output switch.The control loop is self-oscillating,producing pulses of up to5s maximum duration(switch'on'),at a frequency that varies in proportion to the LED current.The feedback loop maintains a voltage of V REF at the FB pin and therefore defines a maximum LED current equal to V REF divided by R1.The minimum'off'time of the output switch is fixed at0.5s nominal,to allow time for the coil's energy to be dissipated before the switch is turned on again.This maintains stable and efficient operation in discontinuous mode.Open circuit protectionThere is an internal avalanche diode between the V SENSE and FB pins of the device.This diode,together with the associated resistors provides open circuit protection when the V SENSE pin is connected to the output voltage.In the event of an open circuit condition,the output voltage will rise above the breakdown voltage of the internal diode,which will then conduct and override the control signal from the current sense resistor.This maintains the output voltage at a level below the breakdown voltage of the output switch.Supply current in this condition will fall to a low value as the control loop provides only the bias current for the diode.Filtered PWM operationThe input of an internal low pass filter is switched to V REF when the EN pin is high and switched to ground when the EN pin is low.The output of this filter drives the comparator within the control loop.A continuous high state on EN therefore provides a filtered voltage of value V REF to the comparator.However,by varying the duty cycle of the EN signal at a suitably high frequency (f>10kHz),the control loop will see a voltage,that has an average value equal to the duty cycle multiplied by V REF.This provides a means of adjusting the output current to a lower value.It also allows the device to be both turned on and adjusted with a single signal at the 'EN'pin.The output during this mode of operation will be a dc current equal to (V REF/R1) x duty cycleGated PWM operationThe internal circuitry of the ZXLD1100is turned off when no signal is present on the'EN'pin for more than 120s(nominal).A low frequency signal applied to the EN pin will therefore gate the device'on'and'off'at the gating frequency and the duty cycle of this signal can be varied to provide a'chopped'output current equal to(V REF/R1)x duty cycle.For best accuracy,the gating frequency should be made as low as possible(e.g. below1kHz),such that the turn off delay of the chip is only a small proportion of the gating periodFurther details of setting output current are given in the applications section under brightness control.ZXLD1100S E M I C O N D U C T O R SISSUE 4 -

JULY 20047TYPICAL OPERATING CHARACTERISTICS(For typical applications circuit at V IN =3V, L=10H Coilcraft DO1608C Series, 3 series LEDs,I=15mA, T =25 °C unless otherwise stated)APPLICATIONSProgramming the maximum LED currentThe maximum LED current is programmed by adding a single resistor in series with the LED chain.The current is determined by the resistor value and feedback voltage and is given by:I LED= V FB/R1where V FB=100mVThe table below gives recommended resistor values for required LED currents:Dimming Control via a PWM signal on the EN pinA Pulse Width Modulated(PWM)signal can be applied to the EN pin in order to adjust the output current to a value below the maximum LED current.Two modes of adjustment are possible as described below.True Analog Dimming - Filtered ‘DC’ modeIf a PWM signal of10kHz or higher is applied to the EN pin,the device will remain active when the EN pin is low.However,the input to the internal low pass filter will be switched alternately from V REF to ground,with a duty cycle(D)corresponding to that of the PWM signal. This will present a filtered dc voltage equal to the duty cycle multiplied by V REF to the control loop and will produce a dc output current lower than the maximum set value. This current is given by:I OUTdc= 0.1D/R1This mode of adjustment minimizes flicker in the light output and system noise.Pulsed Dimming - Gated ModeIf a lower frequency of1kHz or less is applied to the EN pin,the device will be gated‘on’and‘off’at a duty cycle (D)corresponding to that of the input signal.The average output current is then given by:I OUTavg»0.1D/R1This mode may be preferred over dc current control if the purest white output is required.However,note the 120s nominal turn-off delay of the device,when using the device in this mode.Dimming Control using a DC voltageFor applications where the EN pin is not available a DC voltage can be used to control dimming.By adding resistors R2and R3and applying a DC voltage,the LED current can be adjusted from100%to0%.As the DC voltage increases,the voltage drop across R2increases and the voltage drop across R1decreases,thus reducing the current through the LEDs.Selection of R2 and R3should ensure that the current from the DC voltage is much less than the LED current and much larger than the feedback current.The component values in the diagram below represent0%to100% dimming control from a 0 to 2V DC voltage.Dimming Control using a logic signalFor applications where the LED current needs to be adjusted in discrete steps a logic signal can be applied as shown in the diagram below.When Q1os‘off’,R1 sets the minimum LED current.When Q1is‘on’,R2sets the LED current that will be added to the minimum LED current.The formula for selecting values for R1and R2 are given below:MOSFET ‘off’IVRLED MINFBLED()MOSFET‘on’IVRILED MAXLEDLED MINFB()()where V FB= 100mVZXLD1100S E M I C O N D U C T O R SISSUE 4 - JULY 20048Open circuit protectionThe voltage sense pin(V SENSE)can be connected to the output to provide open circuit protection for the device and external circuits when driving series connected LEDs,thus eliminating the need for an external Zener diode.Protection is provided by the internal avalanche diode(ZD),which limits the maximum output voltage to a value below the breakdown voltage of the output switch when the connection to the diodes is broken.Capacitor selectionA ceramic capacitor grounded close to the GND pin of the package is recommended at the output of the device.Surface mount types offer the best performance due to their lower inductance.A minimum value of0.22F is advised,although higher values will lower switching frequency and improve efficiency especially at lower load currents.A higher value will also minimize ripple when using the device to provide an adjustable dc output current.A good quality,low ESR capacitor should also be used for input decoupling,as the ESR of this capacitor is effectively in series with the source impedance and lowers overall efficiency.This capacitor has to supply the relatively high peak current to the coil and smooth the current ripple on the input supply.A minimum value of1F is acceptable if the input source is close to the device,but higher values will improve performance at lower input voltages,when the source impedance is high.The input capacitor should be mounted as close as possible to the IC For maximum stability over temperature,capacitors with X7R dielectric are recommended,as these have a much smaller temperature coefficient than other types.A table of recommended manufacturers is provided below:ZXLD1100S E M I C O N D U C T O R SISSUE 4 - JULY 20049Inductor selectionThe choice of inductor will depend on available board space as well as required performance.Small value inductors have the advantage of smaller physical size and may offer lower series resistance and higher saturation current compared to larger values.A disadvantage of lower inductor values is that they result in higher frequency switching,which in turn causes reduced efficiency due to switch losses.Higher inductor values can provide better performance at lower supply voltages.However,if the inductance is too high,the output power will be limited by the internal oscillator,which will prevent the coil current from reaching its peak value.This condition will arise whenever the ramp time (I LX(peak)x L/V IN )exceeds the nominal 5s maximum ‘on’time limit for the LX output.The graphs opposite show the ZXLD1100performance for given inductor values and different manufacturers.Recommended inductor values for the ZXLD1100are in the range 6.8H to 22H.The inductor should be mounted as close to the device as possible with low resistance connections to the LX and VIN pins.Suitable coils for use with the ZXLD1100are shown in the table below:Diode selectionThe rectifier diode (D1)should be a fast low capacitance schottky diode with low reverse leakage at the working voltage.It should also have a peak current rating above the peak coil current and a continuous current rating higher than the maximum output load current.The table below gives some typical characteristics for diodes that can be used with the ZXLD1100:(mA)I R at 30V (A)Package 15SOD32315SOT23Layout considerationsPCB tracks should be kept as short as possible to minimize ground bounce,and the ground pin of the device should be soldered directly to the ground plane.It is particularly important to mount the coil and the input/output capacitors close to the device to minimize parasitic resistance and inductance,which will degrade efficiency.The FB pin is a high impedance input so PCB track lengths to this should also be kept as short as possible to reduce noise pickup.Excess capacitancefrom the FB pin to ground should be avoided.ZXLD1100S E M I C O N D U C T O R SISSUE 4 -

DESCRIPTIONThe ZXCD1000provides complete control and modulation functions at the heart of a high efficiency high performance Class D switching audio amplifier solution.In combination with Zetex HDMOS MOSFET devices,the ZXCD1000provides a high performance audio amplifier with all the inherent benefits of Class D. The ZXCD1000solution uses proprietary circuit design to realise the true benefits of Class D without the traditional drawback of poor distortion performance. The combination of circuit design,magnetic component choice and layout are essential to realising these benefits.FEATURES•>90% efficiency• 4 / 8Ωdrive capability•Noise Floor -115dB for solution•Flat response 20Hz -

AUGUST 2007© Zetex Semiconductors plc 2007ZXCD1000 Class D controller ICA functional block diagram of the ZXCD1000is shown in Figure 2.The on chip series regulators drop the external V CC supply (12V-18V)to the approximate 9V (9VA/9VB)and 5.5V (5V5)supplies required by the internal circuitry.A triangular waveform is generated on chip and is brought out at the OscA and OscB outputs.The frequency of this is set (to ~200kHz)by an external capacitor (C osc )and on chip resistor.The triangular waveform must be externally AC coupled back into the ZXCD1000 at the TriangleA and TriangleB inputs.AC coupling ensures symmetrical operation resulting in minimal system DC offsets.TriangleA is connected to one of the inputs of a comparator and TriangleB is connected to one of the inputs of a second comparator.The other inputs of these two comparators are connected to the AudioA and AudioB inputs,which are anti-phase signals externally derived from the audio input.The triangular wave is an order higher in frequency than the audio input (max 20kHz).The outputs of the comparators toggle every time the TriangleA/B and the (relatively slow)AudioA/B signals cross.ZXCD10004V CCC o s c5V 59V B9V A T r i a n g l e BT r i a n g l e AO s c BO s c AD i s tG n G n d Figure 2.Functional Block DiagramWith no audio input signal applied,the AudioA/B inputs are biased at the mid-point of the triangular wave,and the duty cycle at the output of the comparators is nominally 50%.As the AudioA/B signal ascends towards the peak level,the crossing points with the (higher frequency)triangular wave also ascend.The comparator monitoring these signals exhibits a corresponding increase in output duty cycle.Similarly,as the AudioA/B signal descends,the duty cycle is correspondingly reduced.Thus the audio input Pulse Width Modulates the comparator outputs.This principle is illustrated in Figures 3a,b,c and d.The comparator outputs are buffered and used to drive the OutA and OutB outputs.These in turn drive the speaker load (with the audio information contained in the PWM signal)via the off chip output bridge and single stage L-C filter network.The ramp amplitude is approximately 1V.The AudioA,AudioB,TriangleA and TriangleB inputs are internally biased to a DC voltage of approximately VCC/5.The mid -point DC level of the OscA and OscB triangular outputs is around 2V.The triangular wave at the Cosc pin traverses between about 2.7Vand 3.8V and the dist pin exhibits a roughly square wave from about 1.4V to 2V.(The above voltages may vary in practice and are included for guidance only).ZXCD1000ISSUE 4 -

The speaker is connected as a Bridge Tied Load(BTL). This means that both sides of the speaker are driven from the output bridge and therefore neither side of the speaker connects to ground.This allows maximum power to be delivered to the load,from a given supply voltage.The supply voltage for this solution is nominally 16V for 25W into a 4⍀load.A schematic diagram for the solution is shown in Figure4.The audio input is AC coupled and applied to a low pass filter and a phase splitter built around the NE5532dual op-amp.One of these op-amps is configured as a voltage follower and the other as a X1 inverting amplifier.This produces in phase and inverted signals for application to the ZXCD1000.The op-amp outputs are AC coupled into the ZXCD1000 Audio A and AudioB inputs via simple R-C low pass filters(R16/C3and R15/C7).The op-amps are biased to a DC level of approximately 6V by R11 and R12.The Pulse Width Modulated(PWM)outputs,OutA and OutB,which contain the audio information,are AC coupled and DC restored before driving the Zetex ZXM64P03X and ZXM64N03X PMOS and NMOS output bridge FET’s.AC coupling is via C17,C18,C19 and C20.DC restoration is provided by the D2(A1a)/R4, D1(A4a)/R2and D3(A1a)/R6,D4(A4a)/R9components. This technique allows the output stage supply voltage to be higher than the high level of the OutA and OutB outputs(approximately8.5V),whilst still supplying almost the full output voltage swing to the gates of the bridge FET’s(thereby ensuring good turn on).This can be exploited to yield higher power solutions with higher supply voltages – this is discussed later.The resistor/diode combinations(R5/D2(A16b), R3/D1(A4b),R7/D3(A1b)and R8/D4(A4b))in series with the bridge FET gates,assist in controlling the switching of the bridge FET’s.This design minimises shoot through currents whilst still achieving the low distortion characteristics of the system.The purpose of the special inductors in conjunction with the output capacitors C23,C24,C25and C26is to low pass filter the high frequency switching PWM signal that comes from the bridge.Thus the lower frequency audio signal is recovered and is available at the speakerA and speakerB outputs across which the speaker should be connected.Zetex can offer advice on suitable source for the specialist magnetics.The optional components R17and C3form a Zobel network.The applicability of these depends upon the application and speaker characteristics.Suggested values are 47nF and 10 ohmsEfficiencyThe following plots show the measured efficiency of the Zetex solution at various power levels into both4Ωand8Ωloads.As a comparison,typical efficiency is plotted for a class A-B amplifier.They clearly demonstrate the major efficiency benefits available from the Zetex class D solution.ZXCD1000ISSUE 4 - AUGUST 2007© Zetex Semiconductors plc 20077Figure 5ISSUE 4 - AUGUST 2007© Zetex Semiconductors plc 2007ZXCD10008Class D Mono Open Loop solution (Bridge Tied Load -BTL) Solution - Demonstration boardThe circuit design shown in figure 4is available as a demonstration board to enable evaluation of the circuit excellent performance.Full bill of materials (BOM)and Gerber files are also available.The demonstration board part number is yout and component selection are critical to maximising performance from this solution,the demonstration board and circuit can be used as a guide to facilitate design of production circuits.Zetex applications can advise if any circuit modifications are required for specific requirements.The board can be used to demonstrate the ZXCD amplifier capability with output power typically of 25W into 4⍀or 8⍀load depending on chosen supply voltage.Operating instructions are included in the demonstration board literature.A very important feature of the Zetex solution is that the residual distortion is almost totally free of any crossover artifacts.This lack of crossover distortion sets the ZXCD1000solutions quite apart from most other presently available low cost solutions,which in general suffer from severe crossover distortion problems.It is well known that this kind of distortion is particularly unpleasant to the listener.The two scope traces of Figure 7clearly show the lack of such artifacts with the ZetexsolutionFigure 7aZETEX Class D Solution. (10W into 4Ω)Note lack of Crossover ArtifactsFigure 7bTypical Class D Solution.Note Large Crossover ArtifactsFigure 6Mono solution demonstration boardOther Solutions - Stereo, Closed Loop and Higher Powers. STEREOIt is possible to duplicate the above solution to give a2 channel stereo solution.However if the oscillator frequencies are not locked together,a beat can occur which is acoustically audible.This is undesirable.A stereo solution which avoids this problem can be achieved by synchronising the operating frequencies of both ZXCD1000’s class D controller IC’s,by slaving one device from the other.This is illustrated in Figure8.Great care must be taken when linking the triangle from the master to the slave.Any pickup can cause slicing errors and result in increased distortion.The best connection method is to run two tracks,side by side, from the master to the slave.One of these tracks would be the triangle itself,and the other would be the direct local ground linking the master pin9ground to the slave pin 9 ground.A demonstration board,ZXCD1000EVSOL,is available for a stereo 25W solution.ZXCD1000ISSUE 4 - AUGUST 2007© Zetex Semiconductors plc 20079SLAVEFigure 8 Frequency synchronisation for stereo applicationsISSUE 4 - AUGUST 2007© Zetex Semiconductors plc 2007ZXCD100010F i g u r e 950W M a s t e r C h a n n e l w i t h f e e d b a c kClass D 50W Mono Bridge Tied Load (BTL) Solution with Feedback – Circuit DescriptionWith the addition of feedback(hence closed loop solution)it is possible to obtain even better THD performance.A schematic diagram for this is shown in Figure9.Again proprietary circuit and special magnetic design is necessary to yield the high THD performance and deviation from this could significantly reduce performance.Much of the circuitry is the same as described for the open loop solution.The main differences being a consequence of using the feedback circuitry.The audio input is ac coupled and applied to an op-amp(1/2of U3) configured as a non–inverting amplifier with a gain of approximately 4.Feedback is applied differentially from the bridge outputs via the other half of U3 op-amp.A portion of the single ended output from this op-amp is subtracted from the output of the non-inverting op-amp output above.Overall negative feedback is applied due to the polarity and connection of the signals involved.The audio signal from the above circuitry is applied to a phase splitter as was done for the open loop solution. This is built around the other5532dual op-amp(U2). One of these op-amps is configured as a voltage follower and the other as a X1inverting amplifier.This produces in phase and inverted signals for application to the ZXCD1000Audio A and Audio B inputs respectively.The output circuitry downstream of the ZXCD1000is as described for the open loop solution.In order to support the50W output power of this solution a25V rail is required for a4⍀load.The MOSFETs used are SOT223 packaged (ZXM64N035G and ZXM64P035).Further information on this design is available through Zetex applications.Higher Power SolutionsWith some modifications the applications solutions can be extended to give output power up to100W.The main differences being the supply voltage,the TO220 MOSFETs,and the output magnetics.The magnetics for100W are necessarily larger than required for 25/50W in order to handle the higher load currents.For 100W operation the supply voltage to the circuit is nominally35V with a4⍀load.However the maximum supply voltage to the ZXCD1000class D controller IC is 18V,hence a voltage dropper is required.This could be done,for example,as in the open loop solution described previously.A100W circuit is shown on figure 10.This features a35V bridge supply TO220MOSFETs (ZXM64N035L3and ZXM64P035L3)and also proposed protection circuits for over current and over temperature and an alternative anti pop circuit.Further information on this100W reference design can be obtained through Zetex applications.The ZXCD1000class D controller IC is inherently capable of driving even higher power solutions,with the appropriate external circuitry.However as stated above the maximum supply voltage to the ZXCD1000 class D controller IC is18V and the higher supply voltages must therefore be dropped.Also due consideration must be given to the ZXCD1000output drive levels and the characteristics of the bridge MOSFET’s.The latter must be sufficiently enhanced by the OutA and OutB outputs to ensure the filter and load network is driven properly.If the gate drive of the ZXCD1000is too low for the chosen MOSFET then the OUTA and OUTB signal must be buffered using an appropriate MOSFET driver circuit.Additionally, suitable magnetics are essential to achieve good THD performance.Package detailsThe ZXCD1000is available in a16pin exposed pad QSOP package.The exposed pad on the underside of the package should be soldered down to an area of copper on the PCB,to function as a heatsink.The PCB should have plated through vias to the underside of the board, again connecting to an area of copper.ZXCD1000ISSUE 4 -

(as shown in figure 1.0). The Voltage reference has a maximum current sink capability.This magnitude of current will be influenced by the value of R1which is inserted between V ref and V cc.The value of current flowing through R1can be expressed as:I = (Vcc -Vref) / R1ComparatorThe open collector output is active low and is asserted when Vsense x 10 (Vout) > Vcomp_in.It can be connected to any voltage rail up to Vin via a pull-up resistor.Suggest values for the resistor are in the range of 10-100k⍀.In the case where high load currents or a short circuit occurs,thus reducing the common mode signals(V+, V-)typically below2.2V,the comparator will default to the asserted state.This can eliminate a closed loop system‘latch-up’condition,allowing the controller to remove the applied power.StabilityTo ensure stable operation of the ZXCT1030,it is recommended a decoupling capacitor is placed across the V CC and ground connections.A ceramic10F will be adequate.Pin Name Pin FunctionVcc Supply voltageSense-Negative sense inputSense+Positive sense inputGND GroundComp_in Comparator input,usually aratio of the reference or othercontrol signal.Vref_out Reference outputVout Current Monitor outputvoltageComp_out Open collector comparatoroutputZXCT1030S E M I C O N D U C T O R SPROVISIONAL ISSUE J - MAY 20045V ccSense-Sense+GNDComp_outV outVref_outComp_in12348765PIN CONNECTIONSMSOP8 FIGURE 1.0External resistor for reference levelZXCT1030S E M I C O N D U C T O R S6PROVISIONAL ISSUE J - MAY 2004EuropeZetex GmbHStreitfeldstraße 19D-81673 München GermanyTelefon: (49) 89 45 49 49 0Fax: (49) 89 45 49 49 49europe.sales@AmericasZetex Inc700 Veterans Memorial Hwy Hauppauge, NY 11788USATelephone: (1) 631 360 2222Fax: (1) 631 360 8222usa.sales@Asia PacificZetex (Asia) Ltd3701-04Metroplaza Tower 1Hing Fong Road, Kwai Fong Hong KongTelephone: (852) 26100 611Fax: (852) 24250 494asia.sales@Corporate HeadquatersZetex Semiconductors plcZetex Technology Park,Chadderton Oldham, OL9 9LL United KingdomTelephone (44) 161 622 4444Fax: (44) 161 622 4446hq@These offices are supported by agents and distributors in major countries world-wide.This publication is issued to provide outline information only which (unless agreed by the Company in writing)may not be used,applied or reproduced for any purpose or form part of any order or contract or be regarded as a representation relating to the products or services concerned.The Company reserves the right to alter without notice the specification, design, price or conditions of supply of any product or service.For the latest product information, log on to ©Zetex Semiconductors plc 2004PAD LAYOUT DETAILSDIMMillimetres Inches MINMAX MIN MAX A - 1.10-0.043A10.050.150.0020.006B0.250.400.0100.016C 0.130.230.0050.009D2.903.100.1140.122e 0.65 BSC 0.0256 BSC E 2.903.100.1140.122H 4.90 BSC 0.193 BSC L 0.400.700.0160.028°0°6°0°6°PACKAGE DIMENSIONS。
