The compensation capacitor is typically between 100 pf and 33 nf, and is wired in parallel with the output voltage setting resistor, R2. It provides additional stability for high output voltage, low input-output voltages, and/or very low ESR output capacitors, such as solid tantalum capacitors. CFF=1/(31*1000*R2); This capacitor type can be ceramic, plastic, silver mica, etc. (Because of the unstable characteristics of ceramic capacitors made with Z5U material, they are not recommended.)3A 380KHz 23V Buck DC to DC Converter XL1583 Schottky Diode Selection TableCurrent SurfaceMount ThroughHoleVR (The same as system maximum input voltage)20V 30V 40V 50V 60V1A √1N5817 1N5818 1N5819√1N5820 1N5821 1N5822√MBR320 MBR330 MBR340 MBR350 MBR360 √SK32 SK33 SK34 SK35 SK36√30WQ03 30WQ04 30WQ05√31DQ03 31DQ04 31DQ053A√SR302 SR303 SR304 SR305 SR3063A 380KHz 23V Buck DC to DC Converter XL1583 Typical System Application for 12V ~ 5V/3A VersionFigure6.

The instruction manual must be read and ws, standards, or directives applicable to the intended use must be observed. In relation to hazardous areas, Directive 1999/92/EC must be observed.The corresponding data sheets, declarations of conformity, EC-type-examination certificates, certificates and Control Drawings if applicable (see data sheet) are an integral part of this document. You can find this information under .Mounting/InstallationUse only one conductor per terminal.■If cable glands are needed for installation, the following points must be considered / evaluated:■The cable glands used must be suitably certified for the application■The temperature range of the cable glands must be chosen according tothe application.■The cable glands fitted must not reduce the IP rating.If you use stranded wires, crimp on wire end ferrules.In order to guarantee the temperature classes, ensure that power dissipation is lower than the figure stated in the certificate. Most of the power dissipation arises from current flowing in the cables.In order to minimize power dissipation, observe the maximum possible cable lengths.Observe the tightening torque of the terminal screws.Unused conductors must be either connected to terminals or securely tied down and isolated.If mounting the enclosure on concrete use expanding bolts. If mounting the enclosure to a steel framework use vibration resistant mounting equipment.The insulation stripping length must be considered.To ensure the IP degree of protection:■all seals must be undamaged and correctly fitted■all screws of the surrounding enclosure and its cover must be tightened with the appropriate torque■only cable of the appropriate size must be used in the cable glands ■all cable glands must be tightened with the appropriate torque■all empty cable glands must be sealed with the corresponding plugsWhen installing additional components, make sure that these components are listed in the EC-Type-Examination Certificate of the control station.Select suitable conductors in order to ensure, that the maximum permitted temperature of the conductors fit to the maximum permitted ambient temperature of the control station.The permitted ambient temperatures of the built-in components must not be exceeded.The minimum bending radius has to be adhered to.When installing the conductors the insulation must reach up to the terminal.In order to prevent condensation in the enclosure, use suitable certified breathers.Connect all bare non-energized metal parts to the protective earth conductor.Observe IEC/EN 60079-17 for maintenance and testing.Before opening the enclosure make sure, that the built-in components are de-engergized.When energized, the enclosure may only be opened for maintenance, if only intrinsically safe circuits are used inside the enclosure.If there is a defect, the product must be repaired by Pepperl+Fuchs.When the internal/external ground bolt is supplied loose, the components should be fitted as shown in the figure below.Technical Specifications1Enclosure wall 2Enclosure exterior 3Enclosure interior(F)XL******.CS (formerly .CP)GL*****.CS (formerly .CP)Refer to type code builder in chapter …Typecodes“Refer to type code builder in chapter …Typecodes“Hazardous Area ATEX certificate number SIRA13ATEX3059XIECEx certificate number IECEx SIR 13.0021 (no IECEx for Control Stations fitted withSchmersal controls)CE numberCertification coding for ATEX/IECEx Certification digit in type code 1II 2 GD Ex de IIC T* Gb II 2 GD Ex tb IIIC T** DbCertification digit in type code 3II 2 GD Ex ib IIC T* Gb II 2 GD Ex tb IIIC T** DbCertification digit in type code 5II 2 GD Ex de ib IIC T* Gb II 2 GD Ex tb IIIC T** DbGas/dust temperature class Maximum ambient temperatureTa +55°CTa +40°C Applications with 5°K internal riseT5 / T95°C T6 / T80°C Applications with 10°K internal riseT4 / T130°C T6 / T80°C Applications with 15°K internal riseT4 / T130°C T5 / T95°C When Schmersal controls fittedT4 / T130°CT4 / T130°CRefer to the enclosure certification label for confirmation Minimum ambient temperature -40°C (-25°C / 0°C when fitted with Schmersal controls)-50°C with specific equipment optionsIP RatingIP 66 (IP 65 when fitted with Schmersal controls)0102Dissipation of copper cables in W/mMaximum internal power dissipation (MDP)Dependent on enclosure size and application internal rise – see certification labelMechanical XL/FXL types MaterialStainless steel models 316L Mild steel modelsCR4FinishStainless steel models Electropolished Mild steel modelsPowder coatedGL types Material Glass reinforced polyester FinishAs mouldedAll typesCover screw torque 2 NmEntry threadform Refer to Customer Specific Drawing produced at time of orderingElectrical Maximum voltageDependent on terminals & equipment fitted – see certification labelMaximum currentDependent on terminals, cable & equipment fitted – see certification label ConformityEN 60079-0: 2012EN 60079-7: 2007EN 60079-31: 2009EN 60079-1: 2007EN 60079-11: 2007EN 60529Current (A)Cable CSA 124610161 mm 20.01680.06720.2690.605 1.68 4.32.5 mm 20.006720.02690.1080.2420.672 1.724 mm 20.00420.01680.0670.1510.42 1.086 mm20.00280.01120.0450.1010.280.717(F)XL******.CS (formerly .CP)GL*****.CS (formerly .CP)Refer to type code builder in chapter …Typecodes“Refer to type code builder in chapter …Typecodes“Typecodes(F)XL*.CS Typecode:GL*.CS Typecode:。

二：XL1583 PCB板布局建议：
（1）流大电流的线要粗，短，不拐弯。
（2）4脚（GND），2脚（VIN）线要粗，短线，不拐弯，且输入电解电容CIN和105 C1陶瓷电容紧挨第2脚（VIN）和4脚(GND)。
（主要是为了减小输入电源布线寄生的电感，电阻产生的高压开关毛刺干扰）
（3）3脚（SW）输出线要粗，短线，不拐弯，电感和续流二极管要紧挨第3脚（SW）输出端。
（4）5脚（FB）走线要接到输出滤波电容C2,COUT之后, PCB布线远离L1,D1,避免噪声干扰。
