To preserve maximum flexibility, internal fusing is not included, however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 15 A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used.

However, additional output For the converter output to be considered meeting the filtering may be required by the system designer for a number requirements of safety extra-low voltage (SELV), the input of reasons. First, there may be a need to further reduce the must meet SELV requirements. The power module has extra- output ripple and noise of the module. Second, the dynamic low voltage (ELV) outputs when all inputs are ELV. response characteristics may need to be customized to a particular load step change. The input to these units is to be provided with a fast-acting fuse with a maximum rating of 15A in the positive input lead. To reduce the output ripple and improve the dynamic response to a step load change, additional capacitance at the output can be used. Low ESR polymer and ceramic capacitors are recommended to improve the dynamic response of the module. For stable operation of the module, limit the capacitance to less than the maximum output capacitance as specified in the electrical specification table.

When using Remote Sense, the output voltage of the module can Voltage Sequencing increase, which if the same output is maintained, increases the TM Austin SuperLynx II 12V series of modules include a power output by the module. Make sure that the maximum TM sequencing feature, EZ-SEQUENCE that enables users to output power of the module remains at or below the maximum implement various types of output voltage sequencing in their rated power. When the Remote Sense feature is not being applications. This is accomplished via an additional used, connect the Remote Sense pin to output pin of the sequencing pin.

The SEQ voltage must be set higher than the Sense set-point voltage of the module. The output voltage follows the R LOAD voltage on the SEQ pin on a one-to-one volt basis. By connecting multiple modules together, customers can get multiple modules to track their output voltages to the voltage R R R R distribution contact contact distribution applied on the SEQ pin. COM COM Figure 31. Remote sense circuit configuration. For proper voltage sequencing, first, input voltage is applied to the module. The On/Off pin of the module is left unconnected (or tied to GND for negative logic modules or tied to VIN for positive logic modules) so that the module is ON by default. After applying input voltage to the module, a minimum of 10msec delay is required before applying voltage on the SEQ pin. During this time, potential of 50mV (± 10 mV) is maintained on the SEQ pin. After 10msec delay, an analog voltage is applied to the SEQ pin and the output voltage of the module will track this voltage on a one-to-one volt bases until output reaches the set-point voltage. To initiate simultaneous shutdown of the modules, the SEQ pin voltage is lowered in a controlled manner. Output voltage of the modules tracks the voltages below their set-point voltages on a one-to-one basis. A valid input voltage must be maintained until the tracking and output voltages reach ground potential to ensure a controlled shutdown of the modules. TM When using the EZ-SEQUENCE feature to control start-up of the module, pre-bias immunity feature during start-up is disabled. The pre-bias immunity feature of the module relies on the module being in the diode-mode during start-up. When TM using the EZ-SEQUENCE feature, modules goes through an internal set-up time of 10msec, and will be in synchronous rectification mode when voltage at the SEQ pin is applied. This will result in sinking current in the module if pre-bias voltage is present at the output of the module. When pre-bias immunity TM during start-up is required, the EZ-SEQUENCE feature must TM be disabled. For additional guidelines on using EZ-SEQUENCE TM feature of Austin SuperLynx II 12V, contact GE technical representative for preliminary application note on output voltage sequencing using Austin Lynx II series. Remote Sense TM The Austin SuperLynx II 12V SMT power modules have a Remote Sense feature to minimize the effects of distribution losses by regulating the voltage at the Remote Sense pin (See Figure 31). The voltage between the Sense pin and Vo pin must not exceed 0.5V. January 14, 2016 ©2016 General Electric Company. All rights reserved.

The recommended linear reflow profile using Sn/Ag/Cu solder is shown in Figure. 37. MSL Rating The Austin SuperLynx II 12V SMT modules have a MSL rating of 3. Storage and Handling The recommended storage environment and handling procedures for moisture-sensitive surface mount packages is detailed in J-STD-033 Rev. A (Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices). Moisture barrier bags (MBB) with desiccant are required for MSL ratings of 2 or greater. These sealed packages should not be broken until time of use. Once the original package is broken, the floor life of the product at conditions of ≤ 30°C and 60% relative humidity varies according to the MSL rating (see J-STD-033A). The shelf life for dry packed SMT packages will be a minimum of 12 months from the bag seal date, when stored at the following conditions: < 40° C, < 90% relative humidity. Post Solder Cleaning and Drying Considerations Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly.
