Highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 16 a 33µF electrolytic capacitor (ESR<0.7Ω at 100kHz), mounted close to the power module helps ensure the stability of the unit. Refer to EMC considerations or consult the factory for further application guidelines. LTEST CS Data Sheet October 20, 2008 Safety Considerations For safety-agency approval of the system in which the power module is used, the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standard, i.e., UL 60950-1, CSA C22.2 No. 60950-1rd 03, and VDE 0805 (IEC60950, 3 Edition). If the input source is non-SELV (ELV or a hazardous voltage greater than 60 Vdc and less than or equal to 75Vdc), for the module’s output to be considered as meeting the requirements for safety extra-low voltage (SELV), all of the following must be true: • The input source is to be provided with reinforced insulation from any other hazardous voltages, including the ac mains. • One VIN pin and one VOUT pin are to be grounded, or both the input and output pins are to be kept floating. • The input pins of the module are not operator accessible. • Another SELV reliability test is conducted on the whole system (combination of supply source and subject module), as required by the safety agencies, to verify that under a single fault, hazardous voltages do not appear at the module’s output. Note: Do not ground either of the input pins of the module without grounding one of the output pins. This may allow a non-SELV voltage to appear between the output pins and ground. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. For input voltages exceeding –60 Vdc but less than or equal to –75 Vdc, these converters have been evaluated to the applicable requirements of BASIC INSULATION between secondary DC MAINS DISTRIBUTION input (classified as TNV-2 in Europe) and unearthed SELV outputs (-B option only). The input to these units is to be provided with a maximum 8A fast-acting fuse in the ungrounded lead. LINEAGE POWER Data Sheet October 20, 2008 JQW Series Power Modules; dc-dc Converters 36 to 75 Vdc Input; Single Output up to 25A Feature Descriptions Remote On/Off Enable The module is fitted with a Remote On/Off Enable control feature. This feature allows users to turn the output voltage on and off by means of external circuits. This control feature is primary referenced. The Remote On/Off Enable features positive logic as standard. To turn the power module on and off, the user must supply a switch (open collector or equivalent) to control the voltage (Von/off) between the ON/OFF terminal and the VIN(-) terminal. A logic low (less than 1.2V) applied to the module Remote On/Off Enable pin will disable the output voltage. The typical Ion/off during a logic low is 0.5mA. For reliable operation the switch should maintain a logic low level whilst sinking a minimum of 1.0mA. A logic high voltage on the Remote On/Off Enable pin will enable the output. During a logic high, the typical Von/off generated by the module is 4.2V, and the maximum allowable leakage current in the external device at Von/off = 4.2V is 50µA. The module has an in-built pull-up, avoiding the need to supply an external pull-up. If not using the Remote Of/Off Enable function, leave the pin open (no connection). Vin+ VO(+) back into its specified range. If the output voltage is subjected to a severe fault, such as a short circuit (VO ≤ 0.3V), the over current protection circuitry may cause the module to hiccup off once. The module will then attempt to auto restart and will enter constant current mode if the S/C persists. If the S/C is then removed the module will resume normal operation. Over Temperature Protection These modules feature an over temperature protection circuit to safeguard against thermal damage. The circuit shuts down the module if the over temperature threshold is exceeded. It will then wait for the module to cool sufficiently before automatically attempting to restart. The module will typically enter thermal shutdown when the temperature measured at the thermal reference point Tref (see Figure 23) reaches 120°C. Output Over Voltage Protection The output over voltage protection consists of control circuitry, independent of the primary regulation loop, which monitors the voltage at the output terminals. This redundant circuit has a higher voltage set point than the primary loop (see VO, limit values in the Feature Specifications table). In the unlikely event of a fault, the over voltage loop ensures that the output voltage does not exceed the specified values. As standard the module will attempt to auto recover. Input Under Voltage Lockout Ion/off ON/OFF Von/off Vin- VO(-) At input voltages below the input under voltage lockout limit, the module operation is disabled. The module will only begin to operate once the input voltage is raised above the under voltage lockout turn-on threshold, VUV/ON. Avoid applying reverse polarity input voltage as this may damage the unit. Figure 19. Remote On/Off Implementation Once operating, the module will continue to operate until the input voltage is taken below the under voltage turn-off threshold, VUV/OFF. Output Over Current Protection Input Over Voltage Lockout To provide protection in a fault (output overload) condition, the unit is equipped with internal current-limiting circuitry that can endure current limiting continuously. At the point of current-limit inception, the unit shifts from voltage control to current control (constant current mode). The unit operates normally once the output current is brought At input voltages above the input over voltage lockout limit, the module operation is disabled. The module will shut down if the input voltage is raised above the turn-off threshold, VOV/OFF. The module will auto restart once the input supply drops back below the high voltage turn-on threshold, VOV/ON. LINEAGE POWER 9 JQW Series Power Modules; dc-dc Converters 36 to 75 Vdc Input; Single Output up to 25A With an external resistor between the TRIM and SENSE(-) pins (Radj-down), the output voltage set point (VO, adj) decreases (see Figure 21). Feature Descriptions (continued) Remote Sense Remote sensing minimises the effects of distribution losses by regulating the voltage at the remote-sense connections, i.e. at the point of load (Figure 20).

Circuit Configuration to Decrease Output Voltage Figure 20. Circuit Configuration for Remote Sense Operation The voltage difference between the remote-sense pins and the output terminals must not exceed the output voltage sense range given in the Feature Specifications table, i.e. The following equation determines the required external-resistor value to obtain percentage decease in output voltage change of Δ%. [VO(+) – VO(-)] – [SENSE(+) – SENSE(-)] ≤ 10%VO,nom The voltage between the VO(+) and VO(-) terminals must not exceed the minimum value of the output over voltage protection. This limit includes any increase in voltage due to remote-sense compensation and output voltage set-point adjustment (trim). If not using the remote sense feature to regulate the voltage at the point of load, then connect SENSE(+) to VO(+) and SENSE(-) to VO(-) at the module. Although the output voltage can be increased by both the remote sense and by the trim, the maximum increase for the output voltage is not the sum of the two maximum specifications. The maximum increase is limited to the larger of either the remote sense or the trim value. Example: to trim down 10% Radj-down = 8kΩ With an external resistor connected between the TRIM and SENSE(+) pins (Radj-up), the output voltage set point (VO, adj ) increases (see Figure 22). Vin+ V O+ VO SENSE + Radj-down ON/OFF RLOAD Trim Output Voltage Set-Point Adjustment (TRIM) The trimming feature allows the user to adjust the output voltage set point of the module. If not using the trim feature, leave the TRIM pin open. 10 Vin- VO SENSE VO- Figure 22. Circuit Configuration to Increase Output Voltage LINEAGE POWER Data Sheet October 20, 2008 JQW Series Power Modules; dc-dc Converters 36 to 75 Vdc Input; Single Output up to 25A Feature Descriptions (continued) The following equation determines the required external-resistor value to obtain a percentage increase in the nominal output voltage (VO) of Δ%. Example: to trim nominal 3.3V module up 10% Radj-up = 17.63kΩ The voltage between the VO(+) and VO(-) terminals must not exceed the minimum value of the output over voltage protection. This limit includes any increase in voltage due to remote-sense compensation and output voltage set-point adjustment (trim). See Figure 20. External Output Capacitance In typical applications, the user may add external capacitors to meet the specific demands of his load. Typically, such capacitors present very low impedance, as they often comprise the parallel combination of electrolytic, ceramic and polymer types. These power modules are specified to remain stable, with adequate gain and phase margins, when driving significant values of very low ESR capacitors as specified in ‘Electrical Specifications’. Thermal Considerations DC-DC power converter modules may operate in a variety of thermal environments. 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 reference point, Tref used in the specifications is shown in Figure 23. For reliable operation this temperature should not exceed 110°C. Please refer to the Application Note “Thermal Characterization Process For Open-Frame BoardMounted Power Modules” for a detailed discussion of thermal aspects including maximum device temperatures. LINEAGE POWER Tref Figure 23. Tref Temperature Measurement Location. Heat Transfer via Convection Increased airflow over the module enhances the heat transfer via convection. Derating figures showing the maximum output current that can be delivered versus local ambient temperature (TA) for natural convection and up to 2ms-1 (400 ft./min) forced convection are shown in the Characteristics Curves section. EMC Considerations The JQW series of DC/DC converters contain internal input and output differential filters and employ other techniques to minimize noise and the need for external filtering. However, to meet regulatory conducted emissions standards such as EN55022, Class A it is expected that some external filter components will need to be fitted. Layout Considerations Avoid placing copper areas on the outer layer of the application PCB directly underneath the power module. Also avoid placing via interconnects underneath the power module. For further information on designing for EMC compliance, as well as layout guidelines, refer to the FLTR100V10 data sheet (FDS01-043EPS). 11 JQW Series Power Modules; dc-dc Converters 36 to 75 Vdc Input; Single Output up to 25A Data Sheet October 20, 2008 Feature Descriptions (continued) Through-Hole Lead-Free Soldering Information The RoHS-compliant through-hole products use the SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant components. They are designed to be processed through single or dual wave soldering machines. The pins have an RoHS-compliant finish that is compatible with both Pb and Pb-free wave soldering processes. A maximum preheat rate of 3°C/s is suggested. The wave preheat process should be such that the temperature of the power module board is kept below 210°C. For Pb solder, the recommended pot temperature is 260°C, while the Pb-free solder pot is 270°C max. Not all RoHS-compliant through-hole products can be processed with paste-through-hole Pb or Pb-free reflow process. If additional information is needed, please consult with your Lineage Power representative for more details. 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 Lineage Power Board Mounted Power Modules: Soldering and Cleaning Application Note (AP01-056EPS). 12 LINEAGE POWER Data Sheet October 20, 2008 JQW Series Power Modules; dc-dc Converters 36 to 75 Vdc Input; Single Output up to 25A Mechanical Outline Dimensions are in millimeters and [inches].
