Licensed TRIM- GND SENSE- SENSE-  ISO** 9001 and ISO 14001 certified manufacturing facilities Description TM The GigaTLynx 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 (V = 4.5Vdc-14Vdc) and provide a precisely IN 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 TM and vibration. The Tunable Loop 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. * UL is a registered trademark of Underwriters Laboratories, Inc. † CSA is a registered trademark of Canadian Standards Association. ‡ VDE is a trademark of Verband Deutscher Elektrotechniker e.V. ** ISO is a registered trademark of the International Organization of Standards Document No: DS010-005 ver. 1.23 PDF name: APTS050A0X_ds.pdf TM Data Sheet GigaTLynx SMT Non-isolated Power Modules: September 7, 2011 4.5 – 14Vdc input; 0.7Vdc to 2.0Vdc, 50A Output Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device.

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.

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.
