These modules operate over a 7 to 14Vdc input range and provide a precisely regulated output voltage from 0.6 to 1.5Vdc. The output voltage is programmable via an external resistor and/or PMBus control. Features include a digital interface using the PMBus protocol, remote On/Off, adjustable output voltage, Power Good signal and overcurrent, overvoltage and overtemperature protection. The PMBus interface supports a range of commands to both control and monitor the module. The module also includes a real time compensation loop that allows optimizing 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 # The PMBus name and logo are registered trademarks of the System Management Interface Forum (SMIF) April 20, 2018 ©2017 General Electric Company.

Power Module Wizard GE offers a free web based easy to use tool that helps users simulate the Tunable Loop performance of the TJT170. Go to http://ge.transim.com/pmd/Home and sign up for a free account and use the module selector tool. The tool also offers downloadable Simplis/Simetrix models that can be used to assess transient performance, module stability, etc. Bin ‘a’ and Bin ‘b’ settings using the models available through Power Module Wizard The TJT170 module has a built-in non-linear compensation adjustment to speed up its transient response to dynamic loading conditions. When the module senses a load transition in progress, it automatically adjusts the KD, KI, KP settings to higher values and then reverts to the values set before the transient conditions. The adjustment of the PID coefficients is as follows: Steady State Transient Condition Bin ‘a’ – User set values based on RTUNE or programmed Bin ‘b’ – Controller adjusted values for duration of transient KD KI KP KD KI KP A B X 1.5 x A 2 x B 2 x C For determining the voltage response to a current load transient, it is more accurate to use the Bin ‘b’ settings corresponding to the selected KD, KI, KP values. For Loop Stability Simulations, the selected PID values corresponding to Bin ‘a’ should be used. April 20, 2018 ©2017 General Electric Company. All rights reserved.

The software can be downloaded for free at http://go.ge-energy.com/DigitalPowerInsight.html. A GE USB to I2C adapter and associated cable set are required for proper functioning of the software suite. For first time users, the GE DPI Evaluation Kit can be purchased from leading distributors at a nominal price and can be used across the entire range of GE Digital POL Modules.

Page 33 Data Sheet GE TM 170A TeraDLynx : Non-Isolated DC-DC Power Modules 7Vdc –14Vdc input; 0.6Vdc to 1.5Vdc output; 170A Output Current Thermal Considerations Power modules operate in a variety of thermal environments; however, sufficient cooling should always be provided to help ensure reliable operation. 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 37. The preferred airflow direction for the module is in Figure 38. 25.4_ Wind Tunnel (1.0) PWBs Power Module Figure 38. Preferred airflow direction and location of hot- 76.2_ spots of the module (Tref). (3.0) The thermal reference points, T used in the specifications ref x are also shown in Figure 38. For reliable operation the temperatures at these points should not exceed 120°C. The Probe Location for measuring output power of the module should not exceed the rated 12.7_ airflow and power of the module (Vo,set x Io,max). (0.50) ambient temperature Please refer to the Application Note “Thermal Characterization Process For Open-Frame Board-Mounted Air Power Modules” for a detailed discussion of thermal aspects flow including maximum device temperatures.
