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 in series with the input (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 Tyco Electronics Corp.

Data Sheet January 2000 CC030-Series Power Modules; dc-dc Converters: 18 Vdc to 36 Vdc Inputs, 30 W Design Considerations (continued) Remote On/Off Input Source Impedance 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 16). A logic low is Von/off = -0.7 V to 1.2 V, during which the module is off. The maximum Ion/off during a logic low is 1 mA. The switch should maintain a logiclow voltage while sinking 1 mA. The power module should be connected to a low ac-impedance input source. Source inductance greater than 12 H can affect the stability of the power module. A 33 F electrolytic capacitor (ESR < 0.7 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. (See Figure 14.) 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. 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. VI(+) VI(-) - SENSE(+) Von/off VO(+) + Ion/off REMOTE ON/OFF The input to these units is to be provided with a maximum 5 A normal-blow fuse in the ungrounded lead. LOAD VO(-) SENSE(-) 8-720(C).i Figure 16. Remote On/Off Implementation Feature Descriptions Overcurrent Protection Remote Sense 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. Remote sense minimizes the effects of distribution losses by regulating the voltage at the remote-sense connections. 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, for example, for the CC030Bs: Tyco Electronics Corp. [VO(+) - VO(-)] - [SENSE(+) - SENSE(-)] 0.5 V The voltage between the VO(+) and VO(-) terminals must not exceed 13.2 V. This limit includes any increase in voltage due to remote-sense compensation, set-point adjustment, and trim (see Figure 17). 9 CC030-Series Power Modules; dc-dc Converters: 18 Vdc to 36 Vdc Inputs, 30 W Feature Descriptions (continued) Data Sheet January 2000 The CC030-Series Power Modules have a fixed current-limit 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.

Circuit Configuration to Increase Output Voltage Output voltage adjustment 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 (see Figures 18 and 19).

Circuit Configuration to Decrease Output Voltage Output Overvoltage Protection The output overvoltage clamp consists of control circuitry, which is independent of the primary regulation loop that monitors the voltage on the output terminals. The control loop of the clamp has a higher voltage set point than the primary loop (see Feature Specifications table). This provides a redundant voltage-control that reduces the risk of output overvoltage. Tyco Electronics Corp. CC030-Series Power Modules; dc-dc Converters: 18 Vdc to 36 Vdc Inputs, 30 W Data Sheet January 2000 Thermal Considerations Basic Thermal Performance The CC030-Series Power Modules are designed to operate in a variety of thermal environments. 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. The CC030-Series Power Modules are constructed with a specially designed, heat spreading enclosures. As a result, full load operation in natural convection at 50 C can be achieved without the use of an external heat sink. The thermal data presented is based on measurements taken in a wind tunnel. The test setup shown in Figure 20 was used to collect data for Figures 24 and 25. 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 20. The graphs in Figures 21 through 23 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. 12.7 (0.50) WIND TUNNEL WALL MEASURE CASE TEMPERATURE (TC) AT CENTER OF UNIT AIRFLOW CONNECTORS TO LOADS, POWER SUPPLIES, AND DATALOGGER, 6.35 (0.25) TALL 203.2 (8.00) AIRFLOW 101.6 (4.00) 76.2 (3.00) AIR VELOCITY AND AMBIENT TEMPERATURE MEASURED BELOW THE MODULE 203.2 (8.00) 19.1 (0.75) 8-1046(C) Figure 20.

Figures 21 through 23 show typical power dissipation for these 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 24. For example, if the unit dissipates 6.2 W, the minimum airflow in a 80 C environment is 1.0 ms-1 (200 ft./min).

Heat Sink Selection 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). Figure 25 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 7.1 W of heat in an 80 C environment with an airflow of 0.5 ms-1 (100 ft./min.), the minimum heat sink required can be determined as follows: ( T C, max - T A ) P D where: Tc, max TA = = = PD = module's total thermal resistance case temperature (See Figure 20.) inlet ambient temperature (See Figure 20.) power dissipation (100 - 80)/7.1 2.8 C/W It is important to point out that the thermal resistances shown in Figure 25 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 25 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).
