General DescriptionThe MAX13080E–MAX13089E +5.0V, ±15kV ESD-protect-ed, RS-485/RS-422 transceivers feature one driver and one receiver. These devices include fail-safe circuitry,guaranteeing a logic-high receiver output when receiver inputs are open or shorted. The receiver outputs a logic-high if all transmitters on a terminated bus are disabled (high impedance). The MAX13080E–MAX13089E include a hot-swap capability to eliminate false transitions on the bus during power-up or hot insertion.The MAX13080E/MAX13081E/MAX13082E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 250kbps. The MAX13083E/MAX13084E/MAX13085E also feature slew-rate-limited drivers but allow transmit speeds up to 500kbps. The MAX13086E/MAX13087E/MAX13088E driver slew rates are not limited, making transmit speeds up to 16Mbps possible. The MAX13089E slew rate is pin selectable for 250kbps,500kbps, and 16Mbps.The MAX13082E/MAX13085E/MAX13088E are intended for half-duplex communications, and the MAX13080E/MAX13081E/MAX13083E/MAX13084E/MAX13086E/MAX13087E are intended for full-duplex communica-tions. The MAX13089E is selectable for half-duplex or full-duplex operation. It also features independently programmable receiver and transmitter output phase through separate pins.The MAX13080E–MAX13089E transceivers draw 1.2mA of supply current when unloaded or when fully loaded with the drivers disabled. All devices have a 1/8-unit load receiver input impedance, allowing up to 256transceivers on the bus.The MAX13080E/MAX13083E/MAX13086E/MAX13089E are available in 14-pin PDIP and 14-pin SO packages.The MAX13081E/MAX13082E/MAX13084E/MAX13085E/MAX13087E/MAX13088E are available in 8-pin PDIP and 8-pin SO packages.

These devices feature fail-safe circuit-ry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted, or when they are connected to a terminated transmission line with all dri-vers disabled (see the Fail-Safe section). The MAX13080E/MAX13082E/MAX13083E/MAX13085E/ MAX13086E/MAX13088E/MAX13089E also feature a hot-swap capability allowing line insertion without erroneous data transfer (see the Hot Swap Capability section). The MAX13080E/MAX13081E/MAX13082E feature reduced slew-rate drivers that minimize EMI and reduce reflec-tions caused by improperly terminated cables, allowing error-free data transmission up to 250kbps. The MAX13083E/MAX13084E/MAX13085E also offer slew-rate limits allowing transmit speeds up to 500kbps. The MAX13086E/MAX13087E/MAX13088Es’ driver slew rates are not limited, making transmit speeds up to 16Mbps possible. The MAX13089E’s slew rate is selectable between 250kbps, 500kbps, and 16Mbps by driving a selector pin with a three-state driver.The MAX13082E/MAX13085E/MAX13088E are half-duplex transceivers, while the MAX13080E/MAX13081E/ MAX13083E/MAX13084E/MAX13086E/MAX13087E are full-duplex transceivers. The MAX13089E is selectable between half- and full-duplex communication by driving a selector pin (H/F) high or low, respectively.All devices operate from a single +5.0V supply. Drivers are output short-circuit current limited. Thermal-shutdown circuitry protects drivers against excessive power dissi-pation. When activated, the thermal-shutdown circuitry places the driver outputs into a high-impedance state.Receiver Input Filtering The receivers of the MAX13080E–MAX13085E, and the MAX13089E when operating in 250kbps or 500kbps mode, incorporate input filtering in addition to input hysteresis. This filtering enhances noise immunity with differential signals that have very slow rise and fall times. Receiver propagation delay increases by 25% due to this filtering.Fail-Safe The MAX13080E family guarantees a logic-high receiver output when the receiver inputs are shorted or open, or when they are connected to a terminated transmission line with all drivers disabled. This is done by setting the receiver input threshold between -50mV and -200mV. If the differential receiver input voltage (A - B) is greater than or equal to -50mV, RO is logic-high. If (A - B) is less than or equal to -200mV, RO is logic-low. In the case of a terminated bus with all transmitters disabled, the receiv-er’s differential input voltage is pulled to 0V by the termi-nation. With the receiver thresholds of the MAX13080E family, this results in a logic-high with a 50mV minimumnoise margin. Unlike previous fail-safe devices, the-50mV to -200mV threshold complies with the ±200mVEIA/TIA-485 standard.Hot-Swap Capability (Except MAX13081E/MAX13084E/MAX13087E)Hot-Swap InputsWhen circuit boards are inserted into a hot or powered backplane, differential disturbances to the data buscan lead to data errors. Upon initial circuit board inser-tion, the data communication processor undergoes itsown power-up sequence. During this period, the processor’s logic-output drivers are high impedanceand are unable to drive the DE and RE inputs of these devices to a defined logic level. Leakage currents up to±10µA from the high-impedance state of the proces-sor’s logic drivers could cause standard CMOS enableinputs of a transceiver to drift to an incorrect logic level. Additionally, parasitic circuit board capacitance couldcause coupling of V CC or GND to the enable inputs. Without the hot-swap capability, these factors could improperly enable the transceiver’s driver or receiver.When V CC rises, an internal pulldown circuit holds DElow and RE high. After the initial power-up sequence,the pulldown circuit becomes transparent, resetting thehot-swap tolerable input.Hot-Swap Input CircuitryThe enable inputs feature hot-swap capability. At theinput there are two NMOS devices, M1 and M2 (Figure 9). When V CC ramps from zero, an internal 7µstimer turns on M2 and sets the SR latch, which alsoturns on M1. Transistors M2, a 1.5mA current sink, andM1, a 500µA current sink, pull DE to GND through a5kΩresistor. M2 is designed to pull DE to the disabledstate against an external parasitic capacitance up to100pF that can drive DE high. After 7µs, the timer deactivates M2 while M1 remains on, holding DE low against three-state leakages that can drive DE high. M1 remains on until an external source overcomes the required input current. At this time, the SR latch resetsand M1 turns off. When M1 turns off, DE reverts to a standard, high-impedance CMOS input. Whenever V CCdrops below 1V, the hot-swap input is reset.For RE there is a complementary circuit employing two PMOS devices pulling RE to V CC. MAX13080E–MAX13089E+5.0V, ±15kV ESD-Protected, Fail-Safe, Hot-Swap, RS-485/RS-422 TransceiversM A X 13080E –M A X 13089EMAX13089E ProgrammingThe MAX13089E has several programmable operating modes. Transmitter rise and fall times are programma-ble, resulting in maximum data rates of 250kbps,500kbps, and 16Mbps. To select the desired data rate,drive SRL to one of three possible states by using a three-state driver: V CC , GND, or unconnected. F or 250kbps operation, set the three-state device in high-impedance mode or leave SRL unconnected. F or 500kbps operation, drive SRL high or connect it to V CC .F or 16Mbps operation, drive SRL low or connect it to GND. SRL can be changed during operation without interrupting data communications.Occasionally, twisted-pair lines are connected backward from normal orientation. The MAX13089E has two pins that invert the phase of the driver and the receiver to cor-rect this problem. F or normal operation, drive TXP and RXP low, connect them to ground, or leave them uncon-nected (internal pulldown). To invert the driver phase,drive TXP high or connect it to V CC . To invert the receiver phase, drive RXP high or connect it to V CC . Note that the receiver threshold is positive when RXP is high.The MAX13089E can operate in full- or half-duplex mode. Drive H/F low, leave it unconnected (internal pulldown), or connect it to GND for full-duplex opera-tion. Drive H/F high for half-duplex operation. In full-duplex mode, the pin configuration of the driver and receiver is the same as that of a MAX13080E. In half-duplex mode, the receiver inputs are internally connect-ed to the driver outputs through a resistor-divider. This effectively changes the function of the device’s outputs.Y becomes the noninverting driver output and receiver input, Z becomes the inverting driver output and receiver input. In half-duplex mode, A and B are still connected to ground through an internal resistor-divider but they are not internally connected to the receiver.±15kV ESD ProtectionAs with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against electro-static discharges encountered during handling and assembly. The driver outputs and receiver inputs of the MAX13080E family of devices have extra protection against static electricity. Maxim’s engineers have devel-oped state-of-the-art structures to protect these pins against ESD of ±15kV without damage. The ESD struc-tures withstand high ESD in all states: normal operation,shutdown, and powered down. After an ESD event, the MAX13080E–MAX13089E keep working without latchup or damage.ESD protection can be tested in various ways. The transmitter outputs and receiver inputs of the MAX13080E–MAX13089E are characterized for protec-tion to the following limits:•±15kV using the Human Body Model•±6kV using the Contact Discharge method specified in IEC 61000-4-2ESD Test ConditionsESD performance depends on a variety of conditions.Contact Maxim for a reliability report that documents test setup, test methodology, and test results.Human Body ModelFigure 10a shows the Human Body Model, and Figure 10b shows the current waveform it generates when dis-charged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest,which is then discharged into the test device through a 1.5k Ωresistor.IEC 61000-4-2The IEC 61000-4-2 standard covers ESD testing and performance of finished equipment. However, it does not specifically refer to integrated circuits. The MAX13080E family of devices helps you design equip-ment to meet IEC 61000-4-2, without the need for addi-tional ESD-protection components.+5.0V , ±15kV ESD-Protected, Fail-Safe, Hot-Swap, RS-485/RS-422 TransceiversThe major difference between tests done using the Human Body Model and IEC 61000-4-2 is higher peak current in IEC 61000-4-2 because series resistance is lower in the IEC 61000-4-2 model. Hence, the ESD with-stand voltage measured to IEC 61000-4-2 is generally lower than that measured using the Human Body Model. Figure 10c shows the IEC 61000-4-2 model, and Figure 10d shows the current waveform for IEC 61000-4-2 ESD Contact Discharge test.Machine Model The machine model for ESD tests all pins using a 200pF storage capacitor and zero discharge resis-tance. The objective is to emulate the stress caused when I/O pins are contacted by handling equipment during test and assembly. Of course, all pins require this protection, not just RS-485 inputs and outputs.Applications Information256 Transceivers on the BusThe standard RS-485 receiver input impedance is 12kΩ(1-unit load), and the standard driver can drive up to 32-unit loads. The MAX13080E family of transceivers has a1/8-unit load receiver input impedance (96kΩ), allowingup to 256 transceivers to be connected in parallel on one communication line. Any combination of these devices,as well as other RS-485 transceivers with a total of 32-unit loads or fewer, can be connected to the line.Reduced EMI and ReflectionsThe MAX13080E/MAX13081E/MAX13082E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to250kbps. The MAX13083E/MAX13084E/MAX13085Eoffer higher driver output slew-rate limits, allowing transmit speeds up to 500kbps. The MAX13089E withSRL = V CC or unconnected are slew-rate limited. WithSRL unconnected, the MAX13089E error-free data transmission is up to 250kbps. With SRL connected toV CC,the data transmit speeds up to 500kbps. MAX13080E–MAX13089E+5.0V, ±15kV ESD-Protected, Fail-Safe, Hot-Swap, RS-485/RS-422 TransceiversM A X 13080E –M A X 13089ELow-Power Shutdown Mode (Except MAX13081E/MAX13084E/MAX13087E)Low-power shutdown mode is initiated by bringing both RE high and DE low. In shutdown, the devices typically draw only 2.8µA of supply current.RE and DE can be driven simultaneously; the devices are guaranteed not to enter shutdown if RE is high and DE is low for less than 50ns. If the inputs are in this state for at least 700ns, the devices are guaranteed to enter shutdown.Enable times t ZH and t ZL (see the Switching Characteristics section) assume the devices were not in a low-power shutdown state. Enable times t ZH(SHDN)and t ZL(SHDN)assume the devices were in shutdown state. It takes drivers and receivers longer to become enabled from low-power shutdown mode (t ZH(SHDN), t ZL(SHDN))than from driver/receiver-disable mode (t ZH , t ZL ).Driver Output ProtectionTwo mechanisms prevent excessive output current and power dissipation caused by faults or by bus contention.The first, a foldback current limit on the output stage,provides immediate protection against short circuits over the whole common-mode voltage range (see the Typical Operating Characteristics ). The second, a thermal-shut-down circuit, forces the driver outputs into a high-imped-ance state if the die temperature exceeds +175°C (typ).Line LengthThe RS-485/RS-422 standard covers line lengths up to 4000ft. F or line lengths greater than 4000ft, use the repeater application shown in Figure 11.Typical ApplicationsThe MAX13082E/MAX13085E/MAX13088E/MAX13089E transceivers are designed for bidirectional data commu-nications on multipoint bus transmission lines. F igures 12 and 13 show typical network applications circuits. To minimize reflections, terminate the line at both ends in its characteristic impedance, and keep stub lengths off the main line as short as possible. The slew-rate-lim-ited MAX13082E/MAX13085E and the two modes of the MAX13089E are more tolerant of imperfect termination.Chip InformationTRANSISTOR COUNT: 1228PROCESS: BiCMOS+5.0V , ±15kV ESD-Protected, Fail-Safe, Hot-Swap, RS-485/RS-422 TransceiversFigure 11.

conditions,see the Electrical Characteristics.Note 2:Voltage internally clamped.If clamp voltage is exceeded,limit current to a maximum of 1mA.Note 3:The human body model is a 100pF capacitor discharged through a 1.5k resistor;the Machine Model is 200pF discharged through a 0Ωresistor.Note 4:Typical numbers are at 25˚C and represent the most likely norm.Note 5:All limits guaranteed at room temperature (standard type face)and at temperature extremes (bold type face).All room temperature limits are 100%production tested.All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC)methods.All limits are used to calculate Average Outgoing Quality Level (AOQL).Note 6:External components such as the catch diode,inductor,input and output capacitors can affect switching regulator system performance.When the LM2590HV-AQ is used as shown in the Figure 1test circuit,system performance will be as shown in system parameters section

1.Standard Test Circuits and Layout GuidesL M 2590H V -A Q 10Block Diagram20097130Pin Functions+V IN(Pin1)—This is the positive input supply for the IC switching regulator.A suitable input bypass capacitor must be present at this pin to minimize voltage transients and to supply the switching currents needed by the regulator. Output(Pin2)—Internal switch.The voltage at this pin switches between approximately(+V IN−V SAT)and approxi-mately−0.5V,with a duty cycle of V OUT/V IN.Error Flag(Pin3)—Open collector output that goes active low(≤1.0V)when the output of the switching regulator is out of regulation(less than95%of its nominal value).In this state it can sink maximum3mA.When not low,it can be pulled high to signal that the output of the regulator is in regulation(power good).During power-up,it can be pro-grammed to go high after a certain delay as set by the Delay pin(Pin5).The maximum rating of this pin should not be exceeded,so if the rail to which it will be pulled-up to is higher than45V,a resistive divider must be used instead of a single pull-up resistor,as indicated in Figure1.Ground(Pin4)—Circuit ground.Delay(Pin5)—This sets a programmable power-up delay from the moment that the output reaches regulation,to the high signal output(power good)on Pin3.A capacitor on this pin starts charging up by means on an internal()3µA) current source when the regulated output rises to within5% of its nominal value.Pin3goes high(with an external pull-up)when the voltage on the capacitor on Pin5exceeds 1.3V.The voltage on this pin is clamped internally to about 1.7V.If the regulated output drops out of regulation(less than95%of its nominal value),the capacitor on Pin5is rapidly discharged internally and Pin3will be forced low in about1/1000th of the set power-up delay time.Feedback(Pin6)—Senses the regulated output voltage to complete the feedback loop.This pin is directly connected tothe Output for the fixed voltage versions,but is set to1.23Vby means of a resistive divider from the output for the Adjustable version.If a feedforward capacitor is used(Ad-justable version),then a negative voltage spike is generatedon this pin whenever the output is shorted.This happens because the feedforward capacitor cannot discharge fast enough,and since one end of it is dragged to Ground,theother end goes momentarily negative.To prevent the energyrating of this pin from being exceeded,a small-signal Schot-tky diode to Ground is recommended for DC input voltagesabove40V whenever a feedforward capacitor is present(See Figure1).Feedforward capacitor values larger than0.1µF are not recommended for the same reason,whatever bethe DC input voltage.Shutdown/Soft-start(Pin7)—The regulator is in shut-down mode,drawing about90µA,when this pin is driven toa low level(≤0.6V),and is in normal operation when this Pinis left floating(internal-pullup)or driven to a high level(≥2.0V).The typical value of the threshold is1.3V and the pinis internally clamped to a maximum of about7V.If it is drivenhigher than the clamp voltage,it must be ensured by meansof an external resistor that the current into the pin does not exceed1mA.The duty cycle is minimum(0%)if this Pin isbelow 1.8V,and increases as the voltage on the pin is increased.The maximum duty cycle(100%)occurs whenthis pin is at2.8V or higher.So adding a capacitor to this pin produces a softstart feature.An internal current source willcharge the capacitor from zero to its internally clamped value.The charging current is about5µA when the pin isbelow1.3V but is reduced to only1.6µA above1.3V,so asto allow the use of smaller softstart capacitors.LM2590HV-AQPin Functions(Continued)Note If any of the above three features (Shutdown /Soft-start,Error Flag,or Delay)are not used,the respective pins can be left open.20097131FIGURE 2.Soft-Start,Delay,Error OutputL M 2590H V -A QPin Functions(Continued)Inductor Value Selection Guides(For Continuous Mode Operation)20097132FIGURE 3.Timing Diagram for 5V Output20097126FIGURE 4.LM2590HV-3.3-AQLM2590HV-AQInductor Value Selection Guides (For Continuous Mode Operation)(Continued)20097127FIGURE 5.LM2590HV-5.0-AQ20097129FIGURE 6.LM2590HV-ADJ-AQL M 2590H V -A QInductor Value Selection Guides(For Continuous Mode Operation)(Continued)20097165FIGURE7.Current Ripple RatioCoilcraft Inc.Phone(USA):1-800-322-2645Web Address Coilcraft Inc.,Europe Phone(UK):1-236-730595Web Address Pulse Engineering Inc.Phone(USA):1-858-674-8100Web Address Pulse Engineering Inc.,Phone(UK):1-483-401700Europe Web Address Renco Electronics Inc.Phone(USA):1-321-637-1000Web Address Schott Corp.Phone(USA):1-952-475-1173Web Address Cooper Electronic Tech.

SELECTION PROCEDUREApplication Note AN-1197titled"Selecting Inductors for BuckConverters"provides detailed information on this topic.For aquick-start the designer may refer to the nomographs pro-vided in Figure4to Figure6.To widen the choice of theDesigner to a more general selection of available inductors,the nomographs provide the required inductance and alsothe energy in the core expressed in microjoules(µJ),as analternative to just prescribing custom parts.The followingpoints need to be highlighted:1.The Energy values shown on the nomographs apply tosteady operation at the corresponding x-coordinate(rated maximum load current).However under start-up,without soft-start,or a short-circuit on the output,thecurrent in the inductor will momentarily/repetitively hitthe current limit I CLIM of the device,and this currentcould be much higher than the rated load,I LOAD.Thisrepresents an overload situation,and can cause theInductor to saturate(if it has been designed only tohandle the energy of steady operation).However mosttypes of core structures used for such applications havea large inherent air gap(for example powdered irontypes or ferrite rod inductors),and so the inductancedoes not fall off too sharply under an overload.Thedevice is usually able to protect itself by not allowing thecurrent to ever exceed I CLIM.But if the DC input voltageto the regulator is over40V,the current can slew up sofast under core saturation,that the device may not beable to act fast enough to restrict the current.The cur-rent can then rise without limit till destruction of thedevice takes place.Therefore to ensure reliability,it isrecommended,that if the DC Input Voltage exceeds40V,the inductor must ALWAYS be sized to handle aninstantaneous current equal to I CLIM without saturating,irrespective of the type of core structure/material.2.The Energy under steady operation iswhere L is inµH and I PEAK is the peak of the inductorcurrent waveform with the regulator delivering I LOAD.These are the energy values shown in the nomographs.See Example1below.3.The Energy under overload isIf V IN>40V,the inductor should be sized to handlee CLIM instead of the steady energy values.The worstcase I CLIM for the LM2590HV-AQ is3A.The Energyrating depends on the Inductance.See Example2be-low.4.The nomographs were generated by allowing a greateramount of percentage current ripple in the Inductor asthe maximum rated load decreases(see Figure7).Thiswas done to permit the use of smaller inductors at lightloads.Figure7however shows only the’median’valueof the current ripple.In reality there may be a greatspread around this because the nomographs approxi-mate the exact calculated inductance to standard avail-able values.It is a good idea to refer to AN-1197fordetailed calculations if a certain maximum inductor cur-rent ripple is required for various possible reasons.Alsoconsider the rather wide tolerance on the nominal induc-tance of commercial inductors.5.Figure6shows the inductor selection curves for theAdjustable version.The y-axis is’Et’,in Vµsecs.It is theapplied volts across the inductor during the ON time ofthe switch(V IN-V SAT-V OUT)multiplied by the time forwhich the switch is on inµsecs.See Example3below.Example1:(V IN≤40V)LM2590HV-5.0-AQ,V IN=24V,Output5V@0.8A1.A first pass inductor selection is based upon Inductanceand rated max load current.We choose an inductor with theInductance value indicated by the nomograph(Figure5)anda current rating equal to the maximum load current.Wetherefore quick-select a100µH/0.8A inductor(designed for150kHz operation)for this application.2.We should confirm that it is rated to handle50µJ(seeFigure5)by either estimating the peak current or by adetailed calculation as shown in AN-1197,and also that thelosses are acceptable.Example2:(V IN>40V)LM2590HV-5.0-AQ,V IN=48V,Output5V@1A1.A first pass inductor selection is based upon Inductanceand the switch currrent limit.We choose an inductor with theInductance value indicated by the nomograph(Figure5)anda current rating equal to I CLIM.We therefore quick-select a100µH/3A inductor(designed for150kHz operation)for thisapplication.2.We should confirm that it is rated to handle e CLIM by theprocedure shown in AN-1197and that the losses are accept-able.Here e CLIM is:Example3:(V IN≤40V)LM2590HV-ADJ-AQ,V IN=20V,Output10V@1A1.Since input voltage is less than40V,a first pass inductorselection is based upon Inductance and rated max loadcurrent.We choose an inductor with the Inductance valueindicated by the nomograph Figure6and a current ratingequal to the maximum load.But we first need to calculate Etfor the given application.The Duty cycle iswhere V D is the drop across the Catch Diode()0.5V for aSchottky)and V SAT the drop across the switch()1.5V).SoAnd the switch ON time iswhere f is the switching frequency in Hz.SoLM259HV-AQApplication Information(Continued) Therefore,looking at Figure4we quick-select a100µH/1Ainductor(designed for150kHz operation)for this applica-tion.2.We should confirm that it is rated to handle100µJ(see Figure6)by the procedure shown in AN-1197and that the losses are acceptable.(If the DC Input voltage had been greater than40V we would need to consider e CLIM as in Example2above).Note that we have taken V SAT as1.5V which includes an estimated resistive drop across the inductor.This completes the simplified inductor selection procedure. For more general applications and better optimization,the designer should refer to AN-1197.Figure8provides helpful contact information on suggested Inductor manufacturers who may be able to recommend suitable parts,if the require-ments are known.FEEDFORWARD CAPACITOR(Adjustable Output Voltage Version)C FF-A Feedforward Capacitor C FF,shown across R2in Figure1is used when the output voltage is greater than10V or when C OUT has a very low ESR.This capacitor adds lead compensation to the feedback loop and increases the phase margin for better loop stability.If the output voltage ripple is large(>5%of the nominal output voltage),this ripple can be coupled to the feedback pin through the feedforward capacitor and cause the error comparator to trigger the error flag.In this situation,adding a resistor,R FF,in series with the feedforward capacitor,ap-proximately3times R1,will attenuate the ripple voltage at the feedback pin.INPUT CAPACITORC IN—A low ESR aluminum or tantalum bypass capacitor is needed between the input pin and ground pin.It must be located near the regulator using short leads.This capacitor prevents large voltage transients from appearing at the in-put,and provides the instantaneous current needed each time the switch turns on.The important parameters for the Input capacitor are the voltage rating and the RMS current rating.Because of the relatively high RMS currents flowing in a buck regulator’sinput capacitor,this capacitor should be chosen for its RMScurrent rating rather than its capacitance or voltage ratings, although the capacitance value and voltage rating are di-rectly related to the RMS current rating.The voltage rating ofthe capacitor and its RMS ripple current capability mustnever be exceeded.OUTPUT CAPACITORC OUT—An output capacitor is required to filter the outputand provide regulator loop stability.Low impedance or lowESR Electrolytic or solid tantalum capacitors designed for switching regulator applications must be used.When select-ing an output capacitor,the important capacitor parametersare;the100kHz Equivalent Series Resistance(ESR),theRMS ripple current rating,voltage rating,and capacitance value.For the output capacitor,the ESR value is the most important parameter.The ESR should generally not be lessthan100mΩor there will be loop instability.If the ESR is too large,efficiency and output voltage ripple are effected.SoESR must be chosen carefully.CATCH DIODEBuck regulators require a diode to provide a return path forthe inductor current when the switch turns off.This must bea fast diode and must be located close to the LM2590HV-AQusing short leads and short printed circuit traces.Because of their very fast switching speed and low forward voltage drop,Schottky diodes provide the best performance, especially in low output voltage applications(5V and lower).Ultra-fast recovery,or High-Efficiency rectifiers are also agood choice,but some types with an abrupt turnoff charac-teristic may cause instability or EMI problems.Ultra-fast recovery diodes typically have reverse recovery times of50ns or less.The diode must be chosen for its average/RMScurrent rating and maximum voltage rating.The voltagerating of the diode must be greater than the DC input voltage(not the output voltage).SHUTDOWN/SOFT-STARTThis reduction in start up current is useful in situations wherethe input power source is limited in the amount of current itcan deliver.In some applications Soft-start can be used to replace undervoltage lockout or delayed startup functions.If a very slow output voltage ramp is desired,the Soft-start capacitor can be made much larger.Many seconds or even minutes are possible.If only the shutdown feature is needed,the Soft-start capaci-tor can be eliminated.LM2590HV-AQ。

PRODUCT DESCRIPTION
500mV
200µs
The AD823 is a dual precision, 16 MHz, JFET input op amp that can operate from a single supply of +3.0 V to +36 V, or dual supplies of ± 1.5 V to ± 18 V. It has true single supply capability with an input voltage range extending below ground in single supply mode. Output voltage swing extends to within 50 mV of each rail for IOUT ≤ 100 µA providing outstanding output dynamic range. Offset voltage of 800 µV max, offset voltage drift of 2 µV/°C, input bias currents below 25 pA and low input voltage noise provide dc precision with source impedances up to a Gigohm. 16 MHz, –3 dB bandwidth, –108 dB THD @ 20 kHz and 22 V/µs slew rate are provided with a low supply current of 2.6 mA per amplifier. The AD823 drives up to 500 pF of direct capacitive load as a follower, and provides an output current of 15 mA, 0.5 V from the supply rails. This allows the amplifier to handle a wide range of load conditions. This combination of ac and dc performance, plus the outstanding load drive capability results in an exceptionally versatile amplifier for applications such as A/D drivers, high-speed active filters, and other low voltage, high dynamic range systems.

When the Enable signal is Low the input clock pulses will be inhibited and the counter will be held at the state it was in prior to bringing the Enable Low. A High Reset signal clears the counter to zero count.Depending on the device used, a Low on the Division Select in-put will cause a Divide by 6, 60, 120, 360, 600 or 3600. A High on the Division Select will cause a Divide by 5, 50, 100, 300, 500or 3000.All outputs are 50% duty cycle except RED 5, where output is low for two clocks and high for three clocks.CLOCK INPUTIf input signals are less than the Vss or greater than V DD , a series input resistor should be used to limit the maximum input current to 2 mA.MARKING AS FOLLOWS:PART MARKING RED 5/6 RED 6RED 50/60 RED 60RED 100/120 RED 120RED 300/360 RED 360RED 500/600 RED 600RED 3000/3600 RED 3600V DD (V+)LSI12348765OUTPUTRESET V SS (-V)NC DIVISION SELECTENABLECLOCK INPUTPIN ASSIGNMENT - TOP VIEWFIGURE 1The information included herein is believed to be accurate and reliable.

Supply Current in Shutdown Mode < 1µA Low Output Noise at 224µV RMSStable with low cost ceramic capacitorsApplicationsNotebook Computers Cellular Phones PDAsDigital still Camera and Video Recorders Hand-Held Devices Audio CodecGeneral DescriptionThe G923 is a low supply current, high PSRR, and low dropout linear regulator that comes in a space saving SOT-23-5 package. The supply current at no-load is 90µA. In the shutdown mode, the maximum supply current is less than 1µA. Operating voltage range of the G923 is from 2.50V to 5.50V. The over-current protection limit is set at 550mA typical. An over- tem-perature protection circuit is built-in in the G923 to prevent thermal overload. These power saving fea-tures make the G923 ideal for use in the bat-tery-powered applications such as notebook com-puters, cellular phones, and PDA ’s.The G923 has two modes of operation. When the SET pin is connected to ground, its output is a pre-set value: 1.50V~5.00V. There is no external component needed to decide the output voltage. When an output other than the preset value is needed, two external resistors should be used as a voltage divider. The output volt-age is then decided by the resistor ratio. The G923 comes in a space saving SOT-23-5 package.Pin ConfigurationSETOUTSOT-23-5SHDNGNDIN Adjustable modeFixed modeOrdering InformationFor other output voltage, please contact us at sales @Note: T1: SOT-23-5U: Tape & ReelSelector GuideORDER NUMBERORDER NUMBER(Pb free)OUTPUT VOLTAGE (V)MARKINGG923-150T1U G923-150T1Uf 1.50 92AAx G923-160T1U G923-160T1Uf 1.60 92ABx G923-170T1U G923-170T1Uf 1.70 92ACx G923-180T1U G923-180T1Uf 1.80 92ADx G923-190T1U G923-190T1Uf 1.90 92AEx G923-200T1U G923-200T1Uf 2.00 92AFx G923-210T1U G923-210T1Uf 2.10 92AGx G923-220T1U G923-220T1Uf 2.20 92AHx G923-230T1U G923-230T1Uf 2.30 92AIx G923-240T1U G923-240T1Uf 2.40 92AJx G923-250T1U G923-250T1Uf 2.50 92AKx G923-260T1U G923-260T1Uf 2.60 92ALx G923-270T1U G923-270T1Uf 2.70 92AMx G923-280T1U G923-280T1Uf 2.80 92ANx G923-285T1U G923-285T1Uf 2.85 92AOx G923-290T1U G923-290T1Uf 2.90 92APx G923-300T1U G923-300T1Uf 3.00 92AQx G923-310T1U G923-310T1Uf 3.10 92ARx G923-315T1U G923-315T1Uf 3.15 92ASx G923-320T1U G923-320T1Uf 3.20 92ATx G923-330T1U G923-330T1Uf 3.30 92AUx G923-340T1U G923-340T1Uf 3.40 92AVx G923-350T1U G923-350T1Uf 3.50 92AWx G923-360T1U G923-360T1Uf 3.60 92AXx G923-370T1U G923-370T1Uf 3.70 92AYx G923-380T1U G923-380T1Uf 3.80 92AZx G923-390T1U G923-390T1Uf 3.90 92BAx G923-400T1U G923-400T1Uf 4.00 92BBx G923-410T1U G923-410T1Uf 4.10 92BCx G923-420T1U G923-420T1Uf 4.20 92BDx G923-430T1U G923-430T1Uf 4.30 92BEx G923-440T1U G923-440T1Uf 4.40 92BFx G923-450T1U G923-450T1Uf 4.50 92BGx G923-460T1U G923-460T1Uf 4.60 92BHx G923-470T1U G923-470T1Uf 4.70 92BIx G923-475T1U G923-475T1Uf 4.75 92BJx G923-480T1U G923-480T1Uf 4.80 92BKx G923-490T1U G923-490T1Uf 4.90 92BLx G923-500T1U G923-500T1Uf5.0092BMxORDER NUMBERORDER NUMBER(Pb free)MARKING VOLTAGE TEMP.

It consists of an error amplifier, 1.25V bandgap reference, PMOS output transistor, internal feedback voltage divider, mode comparator, shutdown logic, over current protec-tion circuit, and over temperature protection circuit.The mode comparator compares the SET pin voltage with an internal 350mV reference. If the SET pin volt-age is less than 350mV, the internal feedback voltage divider’s central tap is connected to the non-inverting input of the error amplifier. The error amplifier com-pares non-inverting input with the 1.25V bandgap ref-erence. If the feedback voltage is higher than 1.25V, the error amplifier’s output becomes higher so that the PMOS output transistor has a smaller gate-to-source voltage (V GS). This reduces the current carrying capa-bility of the PMOS output transistor, as a result the output voltage decreases until the feedback voltage is equal to 1.25V. Similarly, when the feedback voltage is less than 1.25V, the error amplifier causes the output PMOS to source more current to pull the feedback voltage up to 1.25V. Thus, through this feedback ac-tion, the error amplifier, output PMOS, and the voltage dividers effectively form a unity-gain amplifier with the feedback voltage force to be the same as the 1.25V bandgap reference. The output voltage, V OUT, is then given by the following equation:V OUT = 1.25 (1 + R1/R2). (1) Alternatively, the relationship between R1 and R2 is given by:R1 = R2 (V OUT /1.25 - 1). (2) For the reasons of reducing power dissipation and loop stability, R2 is chosen to be 100KΩ. For G923- 330, R1 is 164K, and the pre-set VOUT is 3.30V. When external voltage divider is used, as shown in Figure 2, the SET pin voltage will be larger than 350mV. The non-inverting input of the amplifier will be connected to the external voltage divider. However, the operation of the feedback loop is the same, so that the conditions of Equations 1 and 2 are still true. The output voltage is still given by Equation 1.Figure 1. Functional DiagramFigure 2. Adjustable Output Using ExternalFeedback ResistorsOver Current ProtectionThe G923 uses a current sense-resistor to monitor the output current. A portion of the PMOS output transis-tor’s current is mirrored to a resistor such that the voltage across this resistor is proportional to the output current. Once the output current exceeds limit thresh-old, G923 would be protected with a limited output current. Further more, when the output is short to ground, the output current would be folded-back to a less limit.Over Temperature ProtectionTo prevent abnormal temperature from occurring, the G923 has a built-in temperature monitoring circuit. When it detects the temperature is above 145°C, the output transistor is turned off. When the IC is cooled down to below 120°C, the output is turned on again. In this way, the G923 will be protected against abnormal junction temperature during operation.Shutdown ModeWhen the SHDN pin is connected a logic low voltage, the G923 enters shutdown mode. All the analog cir-cuits are turned off completely, which reduces the current consumption to only the leakage current. The G923 output pass transistor would get into high im-pedance level. There is an internal discharge path to help to shorten discharge delay time.Operating Region and Power DissipationSince the G923 is a linear regulator, its power dissipa-tion is always given by P = I OUT (V IN - V OUT). The maxi-mum power dissipation is given by:P D(MAX) = (T J - T A) /θJA,=(150°C-25°C)/240°C/W = 520mW Where (T J -T A) is the temperature difference the G923die and the ambient air,θJA, is the thermal resistance of the chosen package to the ambient air. For surface mount device, heat sinking is accomplished by using the heat spreading capabilities of the PC board and its copper traces. In the case of a SOT-23-5 package, the thermal resistance is typically 240°C/Watt. (See Rec-ommended Minimum Footprint) [Figure 3] Refer to Figure 4 is the G923 valid operating region (Safe Op-erating Area) & refer to Figure 5 is maximum power dissipation of SOT-23-5.The die attachment area of the G923’s lead frame is connected to pin 2, which is the GND pin. Therefore, the GND pin of G923 can carry away the heat of the G923 die very effectively. To improve the maximum power providing capability, connect the GND pin to ground using a large ground plane near the GND pin. Applications InformationCapacitor Selection and Regulator Stability Normally, use a 1µF capacitor on the input and a 1µF capacitor on the output of the G923. Larger input ca-pacitor values and lower ESR provide better sup-ply-noise rejection and transient response. A higher- value input capacitor (10µF) may be necessary if large, fast transients are anticipated and the device is lo-cated several inches from the power source.Power-Supply Rejection and Operation from Sources Other than BatteriesThe G923 is designed to deliver low dropout voltages and low quiescent currents in battery powered sys-tems. Power-supply rejection is 65dB at low frequen-cies. As the frequency increases above 20kHz, the output capacitor is the major contributor to the rejec-tion of power-supply noise.When operating from sources other than batteries, improve supply-noise rejection and transient response by increasing the values of the input and output ca-pacitors, and using passive filtering techniques.Load Transient ConsiderationsThe G923 load-transient response graphs show two components of the output response: a DC shift of the output voltage due to the different load currents, and the transient response. Typical overshoot for step changes in the load current from 10mA to 300mA is 8mV. Increasing the output capacitor's value and de-creasing its ESR attenuates transient spikes.Input-Output (Dropout) VoltageA regulator's minimum input-output voltage differential (or dropout voltage) determines the lowest usable sup-ply voltage. In battery-powered systems, this will de-termine the useful end-of-life battery voltage. Because the G923 use a P-channel MOSFET pass transistor, their dropout voltage is a function of R DS(ON) multiplied by the load current.OUTPUTLayout GuideAn input capacitance of ≅ 1µF is required between the G923 input pin and ground (the amount of the capaci-tance may be increased without limit), This capacitor must be located a distance of not more than 1cm from the input and return to a clean analog ground.Input capacitor can filter out the input voltage spike caused by the surge current due to the inductive effect of the package pin and the printed circuit board’s rout-ing wire. Otherwise, the actual voltage at the IN pin may exceed the absolute maximum rating. The output capacitor also must be located a distance of not more than 1cm from output to a clean analog ground. Because it can filter out the output spike caused by the surge current due to the inductive effect of the package pin and the printed circuit board’s rout-ing wire.
