Therefore, it only provides the basic instructions.

The CAN-8823 CAN connector is D-Sub 9-pin. User can connect it directly to CAN-8123/CAN-8223/CAN-8423 with any other standard male 5-pin screw terminal and to CAN-8823 with D-Sub 9-pin connector. T ake a note that the CAN-8423 power pin of CAN connector is useless. Therefore, users need to give CAN-8423 power by using power connector. Please refer to the CAN-8423 Hardware Structure described before. Terminal ResistanceIn order to minimize the reflection effects on the CAN bus line, the CAN bus line has to be terminatedatbothendsbytwoterminalresistances.TheCAN-8123/CAN-8223/CAN-8423/CAN-8823 has the 120Ω terminal resistance inside. The JP2 of the CAN-8123/CAN-8223 and the JP1 of the CAN-8423/CAN-8823 is for terminal resistance.

Then, press “Next” button.Step 3: Then, select a specific device presented in the “Off line Setting” frame, and choose a correct slot module inserted.For example, if the I-87057 and I-8051 modules are inserted in slot 0 and slot 1 respectively, please select 87057 in the list box, and click “Apply Module” to save the configuration.Step 4: After finishing the configuration, users can one-left click on the slot modul e in the “Off Line Setting” frame if need to change the configuration. If the configuration is successful, users can see the correct module name when mouse moving in, for example 87057 on the top of the slot module..Step 5: Then, repeat the step 3~4 to configure the slot 1 to I-8042 module. Then, click “Save Setting” button to finish the off-line parameter settings..Step 6:Then users can press button “Create EDS Module”for create CANopen slave EDS file.Step 7:The two fields, “description” and “create by”, can help users to do some notes in EDS files. If these two fields are empty, the “ICPDAS CANopen I/O Slave Device” and “ICPDAS” will be used as the default value when creating the EDS file.Step 8: Users can select the “PDO Info”, the “Device Info“and the “Module Info” button forpurpose to view the PDO objects, device profile and slot module configuration information. These information dialogs are shown below.If everything is ok, click the “Finish” button to create the EDS file.Note: If users use off-line method to get the EDS file, the objects which are used to record the input/output range of the analog modules will be described to default value in the EDS file. However, the I-87K slot modules hold the input/output range parameter settings in their own EEPROM. It may cause the mismatch between real input/output range setting and EDS file. By the way, II-8KCPSx needs to configure the input/output range settings by using CANopen SDO protocol. For more detail, please refer to the section 5.5 in CAN-8123/CAN-8223/ CAN-8423/CAN-8823 user manual.CAN-8423/CAN-8823 Configuration (On-line mode)Before using the CAN Slave utility, please make sure that you have connected COM1 of the CAN-8423/CAN-8823 with the available COM port on your PC. The architecture is displayed in the following figure. In this example, the CAN-8423 will be used, and slot modules, I-87057, I-8051, I-8024 and I-8017H are plugged in the slot 0, 1, 2, 3 respectively (If users don’t have any slot module, they can also follow this demo to configure their CAN-8423. But some situation or information relative with slot modules will be difference).PCCOM 1 AvailableCOM portRS-232Step 1: Turn off the CAN-8423. Set the “Baud” rotary switch of CAN-8423 to 9 for configuration mode. Then Turn on the CAN-8423.Step 2:Use the “ID” rotary switch and “Baud” rotary switch to set the baud rate of CAN-8423. The node ID is useless when the value exceeds the 7F (127 for decimal format) because of the CANopen spec definition. The relationship between the rotary switch value and practical baud rate is displayed in the following table. Here, use ID 123 and baud rate 1000Kbps for the demo. Therefore, set the “ID” rotary switch to “7B” (7B=7*16+B=112+11=123) and “Baud” rotary switch to 7.Rotary Switch Value Baud rate (K BPS)0 101 202 503 1254 2505 5006 8007 1000Step 3: T o execute the CAN_SL.exe file, and to display the figure, users have to connect a PC COM port and the CAN-8423 or CAN-8823 well. Here, take the PC COM 1 as an example. Click “Connect” button to get the informat ion stored in the CAN-8823.Step 4:Then, users can set the slot information of CAN-8823 in the below of “CAN-8x23 Configure” frame.Step 5: Please select the slot module 3 in the control tab area, and choose the output range inthe channel area. Here, take the selection -5.00V~+5.00V as an example. Because of the feature of I-8017H8 slot module, output range on each channel will be changed in the same way after users select the output range in one of the channels.Step 6:After setting the proper output range, users can click “Set” button to store the configuration. If all of slot module configurations are finished, click “Next” button to next stepStep 7: Then, “EDS File Information” window will pop out. Users can fill the “Description” and “Create by” fields for the EDS file. Also, users can see the CANopen objects information and modules information by clicking the buttons.If User wants to set dynamic PDO COB-ID, input the COB-ID into the field of “PDO setting Result” window.Then press button “ Set Dynamic PDO” to store the dynamic PDO COB-ID.Note1: The CAN-8423/8823 can also create the EDS file by using off-line mode, and set the analog input range or analog output range by using the CANopen SDO protocol. Note2: The function, dynamic PDO setting, is only supported on-line mode.Application ProcedureSetthe CAN-8423/CAN-8823 terminal resistanceConfigure the CAN-8123/CAN-8223/ CAN-8423 by using off-line modeConfigurethe CAN-8423/CAN-8823 byusing on-line mode Set the CAN-8123/CAN-8223/ CAN-8423 terminal resistancePower offthe CAN-8423/CAN-8823Set ID and Baud rate by using rotary switchConnect the CAN-8423/CAN-8823 CAN connector Connect the CAN-8123/CAN-8223/ CAN-8423 CAN connector.Power onthe CAN-8423/CAN-8823Power on the CAN-8123/CAN-8223/ CAN-8423Apply the CAN-8423/CAN-8823 into CANopen network.Apply the CAN-8123/CAN-8223/ CAN-8423 into CANopen network.

2）恒流原理：如图2所示，芯片对IFB1脚电压V IFB1进行采样，将V IFB1与芯片内部基准VADJ 值进行比较，如果高于VADJ值，功率管Q2导通时间会缩短，传递到输出的能量减少；如果低于该值，功率管Q2导通时间会加长，传递到输出的能量增多，经过内部多个周期的调整后，芯片会处于一个动态平衡状态处于个动态平衡状态。

注：以上仅以1通道来做分析，2通道原理与1通道相同。

Orient-chip Semiconductor (SH) Co.LtdD1L1VINOrient-chip Semiconductor (SH) Co.Ltd2、工作频率IC在一个恒定的频率下工作，这个恒定的频率是通过一个连接在RSET 与GND之间的外部电阻R5来设定，其值由以下公式近似得出(KHz)=6380/R5(Kf OP(KHz)6380/R5(KΩ)3、LED电流调整及模拟调光控制模拟调光是通过在引脚ADIM输入大约0.5V~1.5V的电压来实现，当调整VADIM 时，内部基准ADJ相应的在0.1V~0.3V范围调整。

LED电流由与引脚IFB相连的电阻RIFB（R26/R32）设定，由以下公式近似得出：(mA)=VI LED(mA)V ADIM(mV)/5/R IFB (Ω)如果ADIM脚的电压超过1.5V，引脚IFB电压被调整到固定的0.3V。

当OVP1/OVP2脚电压高于0.2V 时，故障解除，IC正常工作。

时故障解除IC正常工作Orient-chip Semiconductor (SH) Co.Ltd3）输出回路短路保护在正常工作期间，当LED电流回路发生短路，即VIFB>1.5*ADJ时，LED 电流开关Q3/Q5立即关断限制电流涌入，此时连接在TIMER脚的电容C4开始由8uA的电流源对它充电。

在C4充电期间，IC定期的打开LED电流开关Q3/Q5检测故障是否还在，如果C4上电压在上升到3V之前故障解除，那么IC恢复正常工作，C4开始放电。

当C4上电压超过3V时故障仍没解除，IC关断并锁定，需重新启动IC进入正常工作。

4）功率MOSFET过流保护功率MOSFET Q1的开关电流通过连接在CS脚的电阻R22/R28反馈到CS1/CS2脚。

当CS1/CS2脚电压超过近似0.5V的典型阈值时，过流保护功CS1/CS2脚当CS1/CS2脚电压超过近似05V的典型阈值时过流保护功能启动，Q1立即被关断并且持续到下一个开关周期的到来。

5）输出过载保护在IC正常工作期间，当IFB1/IFB2脚电压低于ADIM设定电压值的75%时，输出过载保护启动，此时连接在TIMER脚的电容C4开始由8uA的电流源对它充电。

当C4上电压超过3V时故障仍没解除，IC关断并锁定，需重新启动IC进入正常工作。

但在大尺寸LED背光应用中，boost拓扑使用率是最高的，为此以下的讨论就基于boost转换器。

boost转换器存在两种转换模式，即连续与非连续转换模式（CCM 和DCM）。
