These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet.

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 Tyco Electronics MC005-Series Power Modules; dc-dc Converters: 18 Vdc to 36 Vdc Inputs; 5 W Data Sheet September 2000 Electrical Specifications (continued) Table 2.

Source impedances greater than 12 H can affect the stability of the power module. When the source impedance exceeds 12 H, mount a 33 F electrolytic capacitor (ESR < 0.7 at 100 kHz) close to the module input pins. This is also recommended to minimize reflected-ripple current as well as conducted and radiated electromagnetic interference (EMI). 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. Overcurrent Protection Output Ripple If lower output ripples are needed, external L-C filters across the module output terminals are recommended. A 3.9 H, 50 m inductor and a 47 F capacitor with its impedance less than 1.5 at 100 kHz will reduce the output ripple by at least 50%. Output Voltage Reversal CAUTION: Applying a reverse voltage across the module output forward biases an internal diode. Attempting to start the module under this condition can damage the module. 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. 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. Thermal Considerations Although the power module is designed for an 85 C maximum operating ambient temperature, the characterization of the local thermal environment becomes more critical as temperatures exceed 70 C. The maximum operating ambient temperature for the module is based on the maximum safe operating temperature of the devices contained inside it. Variations in local temperature and airflow, as well as the methods and location of measurement for these parameters, can affect the resulting internal temperature rises for a given ambient temperature. For ambient temperatures exceeding 70 C, call technical support for application assistance. 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.
