Description The JC030-Series Power Modules are dc-dc converters that operate over an input voltage range of 18 Vdc to 36 Vdc and provide precisely regulated 2 V, 5 V, 12 V, and 15 V outputs. The outputs are isolated from the inputs, allowing versatile polarity configurations and grounding connections. The modules have maximum power ratings of 30 W at a typical full-load efficiency of 81%. The power modules feature remote on/off, output sense (both negative and positive leads), and output voltage adjustment, which allows output voltage adjustment from 60% to 110% (80% to 110% for the JC030A-M and JC030D-M) of the nominal output voltage. For disk-drive applications, the JC030B-M Power Module provides a motor-start surge current of 3 A. The modules are PC-board mountable and encapsulated in metal cases. The modules are rated to full load at 100 C case temperature with no 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 Data Sheet March 26, 2008 JC030-Series Power Modules: 18 Vdc to 36 Vdc Inputs; 2 Vdc to 15 Vdc Outputs;13 W to 30 W Electrical Specifications (continued) Table 2.

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 remote on/off, device code suffix "1," turns the module off during a logic high and on during a logic low. Standard modules provide positive logic remote on/off. The power module has an isolated case ground pin. The case is not connected internally allowing the user flexibility in grounding. Input Source Impedance The power module should be connected to a low acimpedance input source. Highly inductive source impedances can affect the stability of the power module. 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. 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 1950, CSA C22.2 No. 950-95, and VDE 0805 (EN60950, IEC950). For the converter output to be considered meeting the requirements of safety extra-low voltage (SELV), the input must meet SELV requirements. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. To turn the power module 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 can be an open collector or equivalent (see Figure 22). A logic low is Von/off = -0.7 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 6 V. The maximum allowable leakage current of the switch at Von/off = 6 V is 50 A. The module has internal capacitance to reduce noise at the ON/OFF pin. Additional capacitance is not generally needed and may degrade the start-up characteristics of the module. CAUTION: To avoid damaging the power module or external on/off circuit, the connection between the VI(-) pin and the input source must be made before or simultaneously to making a connection between the ON/OFF pin and the input source (either directly or through the external on/off circuit.) The input to these units is to be provided with a maximum 5 A normal-blow fuse in the ungrounded lead. VI(+) VI(-) Feature Descriptions - SENSE(+) Von/off VO(+) + 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. Lineage Power Ion/off REMOTE ON/OFF LOAD VO(-) SENSE(-) 8-720(C).h Figure 22.

The voltage 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.: [VO(+) - VO(-)] - [SENSE(+) - SENSE(-)] 0.5 V The voltage between the VO(+) and VO(-) terminals must not exceed the minimum output overvoltage shutdown voltage as indicated in the Feature Specifications table. This limit includes any increase in voltage due to remote-sense compensation and output voltage setpoint adjustment (trim). See Figure 23. If not using the remote-sense feature to regulate the output at the point of load, then connect SENSE(+) to VO(+) and SENSE(-) to VO(-) at the module.

The following equation determines the required external resistor value to obtain an output voltage change of %y. 1 + % V O,nom R adj-up = ------------------ - 1 ------------------- 10 k 2.5 %y For example, to increase the output voltage of the JC030B by 5%, the external resistor value must be: 1 + 0.05 12.0 R adj-up = ----------- - 1 --------------------- 10 k = 798 k 2.5 0.05 The combination of the output voltage adjustment and sense range and the output voltage given in the Feature Specifications table cannot exceed 110% of the nominal output voltage between the VO(+) and VO(-) terminals. The JC030 Power Module family has a fixed currentlimit set point. Therefore, as the output voltage is adjusted down, the available output power is reduced. In addition, the minimum output current is a function of the output voltage. As the output voltage is adjusted down, the minimum required output current can increase. VI (+) Output Voltage Adjustment Output voltage 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 SENSE(+) or SENSE(-) pins. With an external resistor between the TRIM and SENSE(-) pins (Radj-down), the output voltage set point (VO, adj) decreases (see Figure 24). The following equation determines the required external resistor value to obtain an output voltage change of %y. 12 ON/OFF CASE VO (+) SENSE(+) RLOAD TRIM Radj-down VI (-) SENSE(-) VO(-) 8-748(C).b Figure 24.

The control loop of the clamp has a higher voltage set point than the primary loop (see Feature Specifications table).

The graphs in Figures 27 through 32 provide general guidelines for use. Actual performance can vary depending on the particular application environment. The maximum case temperature of 100 C must not be exceeded. Basic Thermal Performance The JC030-Series power modules are built with a specially designed, heat spreading enclosure. As a result, full-load operation in natural convection at 50 C can be achieved without the use of an external heat sink. Higher ambient temperatures can be sustained by increasing the airflow or by adding a heat sink. As stated, this data is based on a maximum case temperature of 100 C and measured in the test configuration shown in Figure 26. POWER DISSIPATION, PD (W) The thermal data presented is based on measurements taken in a wind tunnel.

As with any electronic component, sufficient cooling must be provided to help ensure reliable operation. Heat-dissipating components inside the module are thermally coupled to the case to enable heat removal by conduction, convection, and radiation to the surrounding environment.

Figures 27 through 30 show typical power dissipation for those power modules over a range of output currents. With the known power dissipation and a given local ambient temperature, the appropriate airflow can be chosen from the derating curves in Figure 31. For example, if the unit dissipates 6.2 W, the minimum airflow in an 80 C environment is 1.02 ms-1 (200 ft./min.). 14 Lineage Power Data Sheet March 26, 2008 JC030-Series Power Modules: 18 Vdc to 36 Vdc Inputs; 2 Vdc to 15 Vdc Outputs;13 W to 30 W Thermal Considerations (continued) 9 8 POWER DISSIPATION, PD (W) Forced Convection Cooling (continued) POWER DISSIPATION, PD (W) 7 6 VI = 36 V VI = 27 V 5 4 3 VI = 18 V 7 6 5 400 ft./min.

Forced Convection Power Derating with No Heat Sink; Either Orientation 8-1211(C) Figure 29. JC030B-M Power Dissipation vs. Output Current Several heat sinks are available for these modules. The case includes through threaded mounting holes allowing attachment of heat sinks or cold plates from either side of the module. The mounting torque must not exceed 0.56 N-m (5 in.-lb.). 6 POWER DISSIPATION, PD (W) Heat Sink Selection 5 Figure 32 shows the case-to-ambient thermal resistance, (C/W), for these modules. These curves can be used to predict which heat sink will be needed for a particular environment. For example, if the unit dissipates 7 W of heat in an 80 C environment with an airflow of 0.66 ms-1 (130 ft./min.), the minimum heat sink required can be determined as follows: VI = 24 V VI = 36 V 4 3 2 VI = 18 V 1 ( T C, max - T A ) P D 0 0.0 0.2 0.4 0.6 0.8 1.0 1.2 1.4 1.6 1.8 2.0 OUTPUT CURRENT, I O (A) 8-1212(C).a Figure 30. JC030C-M Power Dissipation vs. Output Current where: = module's total thermal resistance TC, max = case temperature (See Figure 26.) TA = inlet ambient temperature (See Figure 26.) PD = power dissipation (100 - 80)/7 2.9 C/W From Figure 32, the 1/2 inch high heat sink or greater is required.

Heat Sink Selection (continued) The thermal resistances shown in Figure 32 are for heat transfer from the sides and bottom of the module as well as the top side with the attached heat sink; therefore, the case-to-ambient thermal resistances shown will generally be lower than the resistance of the heat sink by itself. The data in Figure 32 was taken with a thermally conductive dry pad between the case and the heat sink to minimize contact resistance (typically 0.1 C/W to 0.3 C/W).
