Description
The GigaTLynxTM series of power modules are non-isolated dc-dc converters that can deliver up to 50A of output current. These modules operate over a wide range of input voltage (VIN = 4.5Vdc-14Vdc) and provide a precisely regulated output voltage from 0.7Vdc to 2.0Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage, over current and over temperature protection, output voltage sequencing and paralleling. The Ruggedized version (-D) is capable of operation up to 105°C and withstand high levels of shock and vibration. The Tunable Loop TM feature, allows the user to optimize the dynamic response of the converter to match the load with reduced amount of output capacitance leading to savings on cost and PWB area.

An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of sophisticated power architecture. 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 surface mount, fast acting fuse (ie. Littelfuse 456030 series) with a maximum rating of 30 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. Refer to the fuse manufacturer’s data sheet for further information.

September 7, 2011 GigaTLynxTM SMT Non-isolated Power Modules: 4.5 – 14Vdc input; 0.7Vdc to 2.0Vdc, 50A Output LINEAGE POWER 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 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. When using the EZ-SEQUENCE TM feature to control start-up of the module, pre-bias immunity 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 using the EZ-SEQUENCE TM feature, modules goes through an internal set-up time of 10msec, and will be in synchronous rectification mode when the voltage at the SEQ pin is applied. This will result in the module sinking current if a pre-bias voltage is present at the output of the module. When pre-bias immunity during start-up is required, the EZ-SEQUENCETM feature must be disabled. For additional guidelines on using the EZ- SEQUENCE TM feature please contact the Lineage Power technical representative for additional information. Active Load Sharing (-P Option) For additional power requirements, the Giga TLynxTM 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 Some special considerations apply for design of converters in parallel operation:
- 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 conditions 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 90% of the sum of the individual converters. As an example, for a system of four Giga TLynx TM converters in parallel, the total current drawn should be less that 90% of (4 x 50A) , i.e. less than 180A.
- All modules should be turned on and off together. 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. When not using the active load share feature, share pins should be left unconnected. Power Good The Giga TLynxTM modules provide a Power Good (PGOOD) signal to indicate that the output voltage is within the regulation limits of the power module. The PGOOD signal will be de-asserted to a low state if any condition such as overtemperature, overcurrent or loss of regulation occurs that would result in the output voltage going ±12.5% outside the setpoint value. The PGOOD terminal is internally pulled-up and provides a voltage of ~5V, when asserted, thus eliminating the need for an external source and pull-up resistor. Additional external drive capability can be provided to the PGOOD terminal by using a source less than 5V and a suitable pull-up resistor to keep the overall external current below 4.5mA Tunable Loop The Giga TLynxTM modules have a new feature that optimizes transient response of the module called Tunable LoopTM. External capacitors are usually added to the output of the module for two reasons: to reduce output ripple and noise (see Fig. 23) and to reduce output voltage deviations from the steady-state value in the presence of dynamic load current changes. Adding external capacitance however affects the voltage control loop of the module, typically causing the loop to slow down with sluggish response. Larger values of external capacitance could also cause the module to become unstable. The Tunable Loop TM allows the user to externally adjust the voltage control loop to match the filter network connected to the output of the module. The Tunable Loop TM is implemented by connecting a series R-C between the SENSE and TRIM+ pins of the module, as shown in Fig. 28. This R-C allows the user to externally

The ruggedized modules have been successfully tested to the following conditions: Non operating random vibration: Random vibration tests conducted at 25C, 10 to 2000Hz, for 30 minutes each level, starting from 30Grms (Z axis) and up to 50Grms (Z axis). The units were then subjected to two more tests of 50Grms at 30 minutes each for a total of 90 minutes. Operating shock to 40G per Mil Std. 810F, Method 516.4 Procedure I: The modules were tested in opposing directions along each of three orthogonal axes, with waveform and amplitude of the shock impulse characteristics as follows: All shocks were half sine pulses, 11 milliseconds (ms) in duration in all 3 axes. Units were tested to the Functional Shock Test of MIL-STD-810, Method 516.4, Procedure I - Figure 516.4-4. A shock magnitude of 40G was utilized. The operational units were subjected to three shocks in each direction along three axes for a total of eighteen shocks. Operating vibration per Mil Std 810F, Method 514.5 Procedure I: The ruggedized (-D version) modules are designed and tested to vibration levels as outlined in MIL-STD-810F, Method 514.5, and Procedure 1, using the Power Spectral Density (PSD) profiles as shown in Table 4 and Table 5 for all axes. Full compliance with performance specifications was required during the performance test. No damage was allowed to the module and full compliance to performance specifications was required when the endurance environment was removed. The module was tested per MIL-STD-810, Method 514.5, Procedure I, for functional (performance) and endurance random vibration using the performance and endurance levels shown in Table 4 and Table 5 for all axes. The performance test has been split, with one half accomplished before the endurance test and one half after the endurance test (in each axis). The duration of the performance test was at least 16 minutes total per axis and at least 120 minutes total per axis for the endurance test. The endurance test period was 2 hours minimum per axis.
