7 GUI Operation: The evaluation kit is designed to automatically detect and display the connected power module. Please refer to the power module data sheet for deeper understanding of supported commands and expected operation of the power module. The power module comes pre-configured with default settings. The GUI will allow users to easily change many settings and explore performance options. Note: The store function can be used only -3 times before memory is filled up and the device can not be reprogrammed any more. To ensure highest reliability, we did not use flash memory in this part. User can change settings as often as desired in working memory to try things, but generally should not store to the NVM (non-volatile memory). Settings can be exported to a file to use again later rather than storing to the device s NVM. Store: Load: Store your settings in the FILE menu Export Configuration File. You can load your settings any time during operation by using the FILE menu Import Configuration File. 04 TDK Lambda Americas Inc. ijb_eval rev.0 /7/04 7/3

8 Once the device is powered on and detected by PC on the USB port it will appear on the device list. Immediately below the device list is the status & faults window for the detected device. System mode is for parallel evaluation only I C device name [ I C address ] green except during NVM storage operation shows if the module is ON or OFF indicates if V out is within the limits green when V in is lower than set limit in the fault section green when V in is higher than set limit in the fault section green when V out is lower than set limit in the fault section loss of sense, when V sense is lost module will be set OFF green when V out is higher than set limit in the fault section green when I out is lower than set limit in the fault section green when short circuit protection has not been active green when Temp. is lower than set limit in the fault section green when Temp. is lower than set limit in the fault section green when Temp. is higher than set limit in the fault section green when Temp. is higher than set limit in the fault section indicates invalid or unsupported data indicates communication / memory / logic status Clear Faults can be used to clear any previous fault flags that were raised 04 TDK Lambda Americas Inc. ijb_eval rev.0 /7/04 8/3

9 GUI main screen the output voltage set point can be changed, the margin up & down are automatically updated to keep a correct percentage. The monitoring graphs can be paused, zoomed in, zoomed out using the button bars in the top center of the charts. Data Monitor V out setting ON / OFF switch Margining switches 04 TDK Lambda Americas Inc. ijb_eval rev.0 /7/04 9/3

10 GUI configure tab screen - the configure tab and sub tabs allow the device to be configured in more detail. The basic tab allows the user to change items such as turn on delay and rise time, on/off polarity, and voltage margining range. Users should pay special attention to the Vout Scale Loop button which may need to be changed to exercise the module over the full operating voltage range. This adjustment is generally automatically done by the module in a real / non-ev kit application. Basic Tab If you want to change to higher voltage then you must turn voltage divider on (select 0.857). This will happen automatically if resistor on Vset pin is changed so generally a user does not need to worry about this item, but in case of EV-kit they may need to turn on or off. Select YES to activate and use the Operation button located at bottom of the GENERAL page. 04 TDK Lambda Americas Inc. ijb_eval rev.0 /7/04 0/3

11 The fault tab allows the user to change items such as over current thresholds, input and output over voltage thresholds and response times. There are some soft ware limits and safe guards to help prevent damage to the EV-kit, but users should still exercise care to keep settings within the power module s ratings to avoid inadvertent damage to the kit. Fault: Warning: except for UTP when a fault limit is exceeded a fault signal is indicated, and the module will be shut down. when a warning limit is exceeded a warning signal is indicated, the module will continue operation. 04 TDK Lambda Americas Inc. ijb_eval rev.0 /7/04 /3

12 The store tab allows the user to permanently change the configuration in NVM so values will be retained during next power up. As explained on page 7, this feature generally should not be performed on the EV-kit. Do NOT use "STORE" function. 04 TDK Lambda Americas Inc. ijb_eval rev.0 /7/04 /3
