These modules operate over an extra wide range of input voltage (V = 9Vdc – 36Vdc) and provide a precisely regulated output IN voltage from 3Vdc to 18Vdc, programmable via an external resistor. Two new features added with this family of products are the ability to externally tune the voltage control loop and a variable current limit inversely dependent on output voltage. Other features include remote On/Off, adjustable output voltage, over current, over temperature protection and sync capability. The TM Ruggedized version (-D) is capable of operation up to 105°C and withstand high levels of shock and vibration. The Tunable Loop , 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 and AutoLimit enables the module to deliver the max possible output power across the entire voltage range. The 9-36V ProLynx can also be used for negative output voltage loads through the use of a specific application schematic * 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 1 Output range linked to input voltage range see page 24 March 14, 2017 ©2017 General Electric Company.

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 fast-acting fuse with a maximum rating of 8 A fast acting (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.

Two On/Off logic options are available. In VIN+ the Positive Logic On/Off option, (device code suffix “4” – see Ordering Information), the module turns ON during a logic High Rpullup on the On/Off pin and turns OFF during a logic Low. With the ISS Negative Logic On/Off option, (no device code suffix, see Ordering Information), the module turns OFF during logic High PWM Enable and ON during logic Low. The On/Off signal is always I D1 ON/OFF referenced to ground. ON/OFF Q2 + 22K V ON/OFF For positive logic modules, the circuit configuration for using CSS Q1 22K the On/Off pin is shown in Figure 32. When the external transistor Q1 is in the OFF state, the ON/OFF pin is pulled high GND _ and transistor Q2 is OFF leading to Q3 also being OFF which turns the module ON. The external resistor Rpullup (100k Figure 33. Circuit configuration for using negative On/Off recommended) must be sized so that V is never more ON/OFF logic. than 12V when Q1 is OFF. In particular, if Vpullup is made the same as the input voltage Vin, the resistor R must be large pullup Overcurrent Protection enough so that VON/OFF is never more than 12V. If the On/Off pin To provide protection in a fault (output overload) condition, the is left floating the module will be in the ON state. unit is equipped with internal current-limiting circuitry and can For negative logic On/Off modules, the circuit configuration is endure current limiting continuously. At the point of shown in Fig. 33. When the external transistor Q1 is in the ON current-limit inception, the unit enters hiccup mode. The unit state, the ON/OFF pin is pulled low causing transistor Q2 to be operates normally once the output current is brought back into OFF and the module to be turned ON. To turn the module OFF, its specified range. The 9-36V ProLynx modules employ an Q1 is turned OFF, causing the ON/OFF pin to be pulled high innovative, patent pending, ‘AutoLimit’ capability. This results in turning Q2 ON and the module to be turned OFF. If the On/Off automatic scaling of current limit with output voltage through pin is left floating, the module will be in the ON state. an inverse relationship of the current limit threshold with the output voltage. This feature shown graphically in Fig. 34, allows Vpullup MODULE higher output currents to be drawn from the module at lower +5V output voltages thereby optimizing the power delivery Rpullup capability of the module. 22K ISS 14 I ON/OFF Q2 PWM Enable ON /OFF 22K 12 Q3 + 42K V ON/OFF 10 CSS Q1 22K GN D _ 8 Figure 32.

Instead of directly turning Q1 On, the level shifting circuit is used to turn Q1 On by first turning Q2 ON. When Q1 is in the ON state, the ON/OFF pin is pulled low causing transistor Q5 Figure 47.
