However, additional output filtering may be required by the system designer for a number of reasons. First, there may be a need to further reduce the output ripple and noise of the module. Second, the dynamic response characteristics may need to be customized to a particular load step change. 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. Figure 48 shows the output ripple voltage for various output voltages at 30A of load current with different external capacitance values and an input of 12V. Figure 49 shows data for the 5Vin case for various output voltages at 30A of load current with different external capacitance values.

Safety Considerations For safety agency approval the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standards, i.e., UL 60950, CSA C22.2 No. 60950-00, EN60950 (VDE 0850) (IEC60950, 3rd edition) Licensed. For the converter output to be considered meeting the requirements of safety extra-low voltage (SELV), the input must meet SELV requirements. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. Feature Descriptions Remote On/Off The Austin MegaLynxTM SMT power modules feature a On/Off pin for remote On/Off operation. If not using the On/Off pin, connect the pin to ground (the module will be ON). The On/Off signal (Von/off) is referenced to ground. Circuit configuration for remote On/Off operation of the module using the On/Off pin is shown in Figure 50.

The external resistor R1 should be chosen to maintain 3.0V minimum on the On/Off pin to ensure that the module is OFF when transistor Q1 is in the OFF state. Suitable values for R1 are 4.7K for input voltage of 12V and 3K for 5Vin. During Logic-Low when Q1 is turned ON, the module is turned ON. The ATS030A0X3-62SRHZ and ATS030A0X3-62SRPHZ modules have a higher value resistor of 100K connected internally between the gate and source of the internal FET used to control the PWM Enable line. The On/Off pin can also be used to synchronize the output voltage start-up and shutdown of multiple modules in parallel. By connecting On/Off pins of multiple modules, the output start-up can be synchronized (please refer to characterization curves). When On/Off pins are connected together, all modules will shutdown if any one of the modules gets disabled due to undervoltage lockout or over temperature protection. 5 0.5 1 1.5 Output Voltage(Volts) 2 2.5 Figure 49.

Remote On/Off Implementation using ON/OFF . The Austin MegaLynxTM 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 51). 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 power output by the module. Make sure that the maximum output power of the module remains at or below the maximum rated power. When the Remote Sense feature is not being used, connect the Remote Sense pin to output of the module. Rcontact Rcontact VIN(+) Rdistribution VO Sense RLOAD Rdistribution At input voltages below the input undervoltage lockout limit, the module operation is disabled. The module will begin to operate at an input voltage above the undervoltage lockout turn-on threshold. Output Voltage Programming Remote Sense Rdistribution To provide protection in a fault condition, the unit is equipped with a thermal shutdown circuit. The unit will shutdown if the overtemperature threshold of 125oC is exceeded at the thermal reference point Tref. The thermal shutdown is not intended as a guarantee that the unit will survive temperatures beyond its rating. Once the unit goes into thermal shutdown it will then wait to cool before attempting to restart. Rcontact Rcontact COM Rdistribution The output voltage of the Austin MegaLynxTM can be programmed to any voltage from 0.8dc to 3.63Vdc by connecting a resistor (shown as Rtrim in Figure 52) between Trim and GND pins of the module. Without an external resistor between Trim and GND pins, the output of the module will be 0.8Vdc. To calculate the value of the trim resistor, Rtrim for a desired output voltage, use the following equation: 1200 Rtrim = - 100 Vo - 0.80 Rtrim is the external resistor in Vo is the desired output voltage By using a 0.5% tolerance trim resistor with a TC of 100ppm, a set point tolerance of 1.5% can be achieved as specified in the electrical specification. Table 1 provides Rtrim values required for some common output voltages. The POL Programming Tool, available at www.gecriticalpower.com under the Design Tools section, helps determine the required external trim resistor needed for a specific output voltage. COM Figure 51. Effective Circuit Configuration for Remote Sense operation. Over Current Protection To provide protection in a fault (output overload) condition, the unit is equipped with internal current-limiting circuitry and can endure current limiting continuously. At the point of current-limit inception, the unit enters hiccup mode. The unit operates normally once the output current is brought back into its specified range. The average output current during hiccup is 10% IO, max. V IN(+) V O(+) ON/OFF TRIM LOAD Rtrim GND Figure 52. Circuit configuration to program output voltage using an external resistor.

Figure 53 shows the circuit configuration for output voltage margining. The POL Programming Tool, available at www.gecriticalpower.com under the Design Tools section, also calculates the values of Rmargin-up and Rmargin-down for a specific output voltage and % margin. Please consult your local GE technical representative for additional details. Vo Rmargin-down Austin Lynx or Lynx II Series required before applying voltage on the SEQ pin. During this delay time, the SEQ pin should be kept at a voltage of 50mV ( 20 mV). After the 10msec delay, the voltage applied to the SEQ pin is allowed to vary and the output voltage of the module will track this voltage on a one-to-one volt basis until the output reaches the set-point voltage. To initiate simultaneous shutdown of the modules, the SEQ pin voltage is lowered in a controlled manner. The output voltages of the modules track the sequence pin voltage when it falls below their set-point voltages. A valid input voltage must be maintained until the tracking and output voltages reach zero to ensure a controlled shutdown of the modules. For a more detailed description of sequencing, please refer to Application Note AN04-008 titled "Guidelines for Sequencing of Multiple Modules". When using the EZ-SEQUENCETM 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 startup. When using the EZ-SEQUENCETM 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 during start-up is required, the EZSEQUENCETM feature must be disabled. Active Load Sharing (-P Option) Q2 Trim Rmargin-up Rtrim For additional power requirements, the Austin MegaLynx series power module is also available with a parallel option. Up to five modules can be configured, in parallel, with active load sharing. Good layout techniques should be observed when using multiple units in parallel. To implement forced load sharing, the following connections should be made: * The share pins of all units in parallel must be connected together. The path of these connections should be as direct as possible. * All remote-sense pins should be connected to the power bus at the same point, i.e., connect all the SENSE(+) pins to the (+) side of the bus. Close proximity and directness are necessary for good noise immunity Q1 GND Figure 53. Circuit Configuration for margining Output voltage. Some special considerations apply for design of converters in parallel operation: Voltage Sequencing The Austin MegaLynxTM series of modules include a sequencing feature that enables users to implement various types of output voltage sequencing in their applications. This is accomplished via an additional sequencing pin. When not using the sequencing feature, either leave the SEQ pin unconnected or tied to VIN. For proper voltage sequencing, first, input voltage is applied to the module. The On/Off pin of the module is or tied to GND so that the module is ON by default. After applying input voltage to the module, a delay of 10msec minimum is January 20, 2016 * When sizing the number of modules required for parallel operation, take note of the fact that current sharing has some tolerance. In addition, under transient condtions such as a dynamic load change and during startup, all converter output currents will not be equal. To allow for such variation and avoid the likelihood of a converter shutting off due to a current overload, the total capacity of the paralleled system should be no more than 75% of the sum of the individual converters. As an example, for a system of four ATS030A0X3-SR converters the parallel, the total (c)2016 General Electric Company. All rights reserved.

This is so that all modules come up at the same time avoiding the problem of one converter sourcing current into the other leading to an overcurrent trip condition. To ensure that all modules come up simultaneously, the on/off pins of all paralleled converters should be tied together and the converters enabled and disabled using the on/off pin. * The share bus is not designed for redundant operation and the system will be non-functional upon failure of one of the unit when multiple units are in parallel. In particular, if one of the converters shuts down during operation, the other converters may also shut down due to their outputs hitting current limit. In such a situation, unless a coordinated restart is ensured, the system may never properly restart since different converters will try to restart at different times causing an overload condition and subsequent shutdown. This situation can be avoided by having an external output voltage monitor circuit that detects a shutdown condition and forces all converters to shut down and restart together.

Thermal Test Setup. Power modules operate in a variety of thermal environments; however, sufficient cooling should always be provided to help ensure reliable operation. The thermal reference points, Tref used in the specifications are shown in Figure 56. For reliable operation the temperatures at these points should not exceed 125oC. The output power of the module should not exceed the rated power of the module (Vo,set x Io,max). Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel. The test set-up is shown in Figure 54. Note that the airflow is parallel to the short axis of the module as shown in Figure 55. The derating data applies to airflow in either direction of the module's long axis.

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 to withstand reflow temperatures of up to 300oC. The label also carries product information such as product code, serial number and location of manufacture. In a conventional Tin/Lead (Sn/Pb) solder process peak reflow temperatures are limited to less than 235oC. Typically, the eutectic solder melts at 183oC, 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. Figure 57. Pick and Place Location. Nozzle Recommendations REFLOW TIME (S) Tin Lead Soldering The Austin MegaLynxTM 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 recommended that the customer review data sheets in order to customize the solder reflow profile for each 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. January 20, 2016 Figure 58. Reflow Profile for Tin/Lead (Sn/Pb) process. MAX TEMP SOLDER (C) The module weight has been kept to a minimum by using open frame construction. Even so, these modules have a relatively large mass when compared to conventional SMT components. Variables such as nozzle size, tip style, vacuum pressure and pick & placement speed should be considered to optimize this process. The minimum recommended inside nozzle diameter for reliable operation is 3mm. The maximum nozzle outer diameter, which will safely fit within the allowable component spacing, is 5 mm max. Figure 59.

Once the original package is broken, the floor life of the product at conditions of <= 30C 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).
