The power module has extra-low response characteristics may need to be customized to a voltage (ELV) outputs when all inputs are ELV. particular load step change. The input to these units is to be provided with a fast-acting fuse with a maximum rating of 20A in the positive input lead.

Two On/Off logic options are ON/OFF TM available in the Austin SuperLynx II series modules. Positive + PWM Enable Logic On/Off signal, device code suffix “4”, turns the module ON V ON/OFF R1 during a logic High on the On/Off pin and turns the module OFF during a logic Low. Negative logic On/Off signal, no device code suffix, turns the module OFF during logic High and turns Q2 CSS Q1 the module ON during logic Low. R2 For positive logic modules, the circuit configuration for using the On/Off pin is shown in Figure 28. The On/Off pin is an open GND _ collector/drain logic input signal (Von/Off) that is referenced to ground. During a logic-high (On/Off pin is pulled high internal Figure 29. Circuit configuration for using negative logic to the module) when the transistor Q1 is in the Off state, the On/OFF power module is ON. Maximum allowable leakage current of the transistor when Von/off = V is 10µA. Applying a logic- IN,max low when the transistor Q1 is turned-On, the power module is Overcurrent Protection OFF.

At the point of current-limit inception, the unit enters hiccup mode. The unit VIN+ MODULE operates normally once the output current is brought back into its specified range.

The module will begin to operate R3 at an input voltage above the undervoltage lockout turn-on threshold.

The module will automatically restart after it For negative logic On/Off devices, the circuit configuration is cools down. shown is Figure 29. The On/Off pin is pulled high with an external pull-up resistor (typical Rpull-up = 68k, +/- 5%). When transistor Q1 is in the Off state, logic High is applied to the On/Off pin and the power module is Off. The minimum On/off voltage for logic High on the On/Off pin is 1.5Vdc. To turn the module ON, logic Low is applied to the On/Off pin by turning ON Q1. When not using the negative logic On/Off, leave the pin unconnected or tie to GND.

Make sure that the maximum Feature Descriptions (continued) output power of the module remains at or below the maximum Voltage Sequencing rated power. When the Remote Sense feature is not being used, connect the Remote Sense pin to the output pin. TM Austin SuperLynx II series of modules include a sequencing feature, EZ-SEQUENCE that enables users to implement various types of output voltage sequencing in their applications. This is R R R R distribution contact contact distribution VIN(+) VO accomplished via an additional sequencing pin. When not using the sequencing feature, either tie the SEQ pin to VIN or Sense leave it unconnected. R LOAD When an analog voltage is applied to the SEQ pin, the output R R R R distribution contact contact distribution COM COM voltage tracks this voltage until the output reaches the set- point voltage. The SEQ voltage must be set higher than the set-point voltage of the module. The output voltage follows the Figure 32. Remote sense circuit configuration 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 applied on the SEQ pin. 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. 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 be disabled. For additional guidelines on using EZ- TM TM SEQUENCE feature of Austin SuperLynx II, contact the GE technical representative for preliminary application note on output voltage sequencing using Austin Lynx II series. Remote Sense TM The Austin SuperLynx 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 32). The voltage between the Sense pin and Vo pin must not exceed 0.5V. The amount of power delivered by the module is defined as the output voltage multiplied by the output current (Vo x Io). When using Remote Sense, the output voltage of the module can increase, which if the same output is maintained, increases the January 14, 2016 ©2016 General Electric Company. All rights reserved.

The modules are fitted with a label designed to provide a large surface area for pick and place operations. The label meets all the requirements for surface mount processing, as well as safety standards, and is able o C. The label to withstand reflow temperatures of up to 300 also carries product information such as product code, serial number and the location of manufacture. Nozzle Recommendations REFLOW TIME (S) The module weight has been kept to a minimum by using open frame construction. Even so, these modules have a Figure 35. Reflow Profile for Tin/Lead (Sn/Pb) process relatively large mass when compared to conventional SMT components. Variables such as nozzle size, tip style, vacuum pressure and placement speed should be considered to optimize this process. The minimum recommended nozzle diameter for reliable operation is 6mm. The maximum nozzle outer diameter, which will safely fit within the allowable component spacing, is 9 mm. Oblong or oval nozzles up to 11 x 9 mm may also be used within the space available. Tin Lead Soldering TM The Austin SuperLynx II SMT power modules are lead free modules and can be soldered either in a lead-free solder process or in a conventional Tin/Lead (Sn/Pb) process. It is o recommended that the customer review data sheets in Figure 36. Time Limit Curve Above 205 C for Tin/Lead order to customize the solder reflow profile for each (Sn/Pb) process application board assembly. The following instructions must be observed when soldering these units. Failure to observe these instructions may result in the failure of or cause damage to the modules, and can adversely affect long-term reliability. In a conventional Tin/Lead (Sn/Pb) solder process peak o reflow temperatures are limited to less than 235 C. o Typically, the eutectic solder melts at 183 C, wets the land, and subsequently wicks the device connection. Sufficient time must be allowed to fuse the plating on the connection to ensure a reliable solder joint. There are several types of SMT reflow technologies currently used in the industry. These surface mount power modules can be reliably soldered using natural forced convection, IR (radiant infrared), or a combination of convection/IR. For reliable soldering the solder reflow profile should be established by accurately measuring the modules CP connector temperatures. January 14, 2016 ©2016 General Electric Company.

The suggested Pb-free solder paste is Sn/Ag/Cu (SAC). The recommended linear reflow profile using Sn/Ag/Cu solder is shown in Fig. 37. MSL Rating The Austin SuperLynx II SMT modules have a MSL rating of 2a. 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. For guidance on appropriate soldering, cleaning and drying procedures, refer to Board Mounted Power Modules: Soldering and Cleaning Application Note (AN04-001).
