Description The LUW025-Series Power Modules are low-profile, open-frame dc-dc converters that operate over an input voltage range of 36 Vdc to 75 Vdc and provide a precisely regulated output. The output is isolated from the input, allowing versatile polarity configurations and grounding connections. The modules feature remote on/off and a wide range of output voltage adjustments. Built-in filtering for both input and output minimizes the need for external filtering.

Fusing Considerations CAUTION: This power module is not internally fused. An input line fuse must always be used. This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of a 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 normal-blow fuse with a maximum rating of 5 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 for further information. 2 Lineage Power LUW025-Series Power Modules: dc-dc Converters: 36 Vdc to 75 Vdc In; 3.3 Vdc and 5 Vdc Out; 16.5 W and 25 W Data Sheet April 2008 Electrical Specifications (continued) Table 2.

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 circuit-board cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly.

Highly inductive source impedances can affect the stability of the power module. For the test configuration in Figure 10, a 33 F electrolytic capacitor (ESR < 0.7 3/4 at 100 kHz) mounted close to the power module helps ensure stability of the unit. For other highly inductive source impedances, consult the factory for further application guidelines. 7 LUW025-Series Power Modules: dc-dc Converters: 36 Vdc to 75 Vdc In; 3.3 Vdc and 5 Vdc Out; 16.5 W and 25 W Data Sheet April 2008 Safety Considerations Remote On/Off 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, CSA C22.2 No. 60950-00, and VDE 0805 (IEC60950). The remote on/off signal is referenced to the primary and is available with either positive or negative logic. Positive logic remote on/off turns the module on during a logic-high voltage on the REMOTE ON/OFF pin, and off during a logic low. Negative logic, device code suffix "1," turns the module off during a logic high and on during a logic low and is the factory-preferred configuration (see the Feature Specifications table). If the input source is non-SELV (ELV or a hazardous voltage greater than 60 Vdc and less than or equal to 75 Vdc), for the module's output to be considered meeting the requirements of safety extra-low voltage (SELV), all of the following must be true: n n n n The input source is to be provided with reinforced insulation from any other hazardous voltages, including the ac mains. One VI pin and one VO 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, as required by the safety agencies, on the combination of supply source and the subject module 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. To turn the power module output on and off, the user must supply a switch to control the voltage between the on/off terminal and the VI(-) terminal (Von/off). The switch may be an open collector or equivalent (see Figure 13). A logic low is Von/off = 0 V to 1.2 V. The maximum Ion/off during a logic low is 1 mA. The switch should maintain a logic-low voltage while sinking 1 mA. During a logic high, the maximum Von/off generated by the power module is 10 V. The maximum allowable leakage current of the switch at Von/off = 10 V is 50 A. Ion/off + REMOTE ON/OFF V O (+) LOAD V on/off - V O (-) V I(-) V I(+) The power module has extra-low voltage (ELV) outputs when all inputs are ELV. The input to these units is to be provided with a maximum 5 A normal-blow fuse in the ungrounded lead. Feature Descriptions Overcurrent Protection To provide protection in a fault (output overload) condition, the unit is equipped with internal current-limiting circuitry and can endure current limiting for an unlimited duration. At the point of current-limit inception, the unit shifts from voltage control to current control. If the output voltage is pulled very low during a severe fault, the current-limit circuit can exhibit either foldback or tailout characteristics (output-current decrease or increase). The unit operates normally once the output current is brought back into its specified range. 8 8-758e Figure 13. Remote On/Off Implementation Output Voltage Set-Point Adjustment (Trim) Output voltage adjustment (trim) allows the user to increase or decrease the output voltage set point of a module. This is accomplished by connecting an external resistor between the TRIM pin and either the VO(+) or VO(-) pin. Connecting an external resistor between the TRIM pin and VO(-) pin (Radj-down) decreases the output voltage set point (see Figure 14). In order to maintain the output voltage accuracy, the trim resistor tolerance should be 0.1%. Lineage Power LUW025-Series Power Modules: dc-dc Converters: 36 Vdc to 75 Vdc In; 3.3 Vdc and 5 Vdc Out; 16.5 W and 25 W Data Sheet April 2008 Feature Descriptions (continued) Output Overvoltage Protection Output Voltage Set-Point Adjustment (Trim) (continued) The output overvoltage clamp consists of control circuitry, independent of the primary regulation loop, that monitors the voltage on the output terminals. This control loop of the protection circuit has a higher voltage set point than the primary loop (see Feature Specifications table). In a fault condition, the overvoltage clamp ensures that the output voltage does not exceed VO, clamp, max. This provides a redundant voltage-control that reduces the risk of output overvoltage.

Circuit Configuration to Decrease Output Voltage The relationship between the output voltage and the trim resistor value for a y% reduction in output voltage is: 511 R adj-down = ---------- - 6.11 k % These modules feature an overtemperature protection circuit to safeguard against thermal damage. The circuit shuts down and latches off the module when the maximum Tref temperature is exceeded. The module will automatically restart when the Tref temperature cools sufficiently. Thermal Considerations Connecting an external resistor between the TRIM pin and VO(+) pin (Radj-up) increases the output voltage set point (see Figure 15). The power modules operate in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation of the unit. Heat is removed by convection and radiation to the surrounding environment. The relationship between the output voltage and the trim resistor value for a y% increase in output voltage is: Considerations include ambient temperature, amount of airflow, module power dissipation, and need for increased reliability.

Circuit Configuration to Increase Output Voltage Lineage Power The monitor temperature reference point, Tref, referenced in the specification is T1. Proper cooling can be verified by measuring the power module's temperature at the top center surface of T1 as shown in Figures 17--18. The temperature at the thermocouple location, T1, should not exceed 110 C during the operation of the module. The output power of the module should not exceed the rated power. The thermal data presented is based on measurements taken in a wind tunnel. The test setup shown in Figure 16 was used to collect data for Figures 17--18. Note that the orientation of the module with respect to airflow affects thermal performance. Two orientations are shown in Figures 17--18. 9 LUW025-Series Power Modules: dc-dc Converters: 36 Vdc to 75 Vdc In; 3.3 Vdc and 5 Vdc Out; 16.5 W and 25 203.2 (8.0) Thermal Considerations (continued) Data Sheet April 2008 Convection Requirements for Cooling To predict the approximate cooling needed for the module, determine the power dissipated as heat by the unit for the particular application.
