The outputs are fully isolated from the inputs, allowing versatile polarity configurations and grounding connections. The modules have maximum power ratings of 10 W at typical fuil-load efficiencies of 80% to 83%. The modules are encapsulated in nonconductive cases that mount on PC boards. In a natural convection environment, the modules are rated to full load at 85 C with no heat sinking or external filtering. For applications requiring remote on/off, the MCO10A1, B1, C1, BK1, and CL1 Power Modules are available. These modules are equivalent to the previously described modules, except for the addition of the remote on/ off and associated terminal. /MC010-Series Power Modules; 18 Vdc to 36 Vdc Inputs, 10 W Absolute Maximum Ratings Stresses in excess of the Absolute Maximum Ratings can cause permanent damage to the device. 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. Exposure to Absolute Maximum Ratings for extended periods can adversely affect device reliability. Specifications apply to all devices.

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 Underwriters Laboratories Conditions of Acceptability requires a normal-blow, dc fuse with a maximum rating of 5 Ain series with the input. Based on the information provided in this data sheet on inrush energy and maxi- mum dc input current, the same type of fuse with a lower rating can be used. However, for UL recognition, the dc rating of the fuse must not exceed 5 A. Refer to the fuse manufacturers data for further information. 2MC010-Series Power Modules; 18 Vdc to 36 Vdc Inputs, 10 W Electrical Specifications (continued) Table 2.

MCO010BK, CL Output Voltage and Efficiency Measurement Test Setup M@@ 0050026 OOebO02l ISTFeature Descriptions Output Overvoltage Clamp The output overvoltage clamp consists of control circuitry, which is independent of the primary regula- tion 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 volt- age-control that reduces the risk of output overvoltage. Current Limit To provide protection in a fault (output overload) condition, the unit is equipped with internal current- limiting 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.

The switch can be an open collector or equivalent (see Figure 5). A logic low is Vonott = 0 V- to 1.2 V, during which the module is on. The maximum lon/o# 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/ot generated by the power module is 18 V. The maximum allowable leakage current of the switch at Vono#t = 18 V is 50 LA. Note: A PWB trace between the on/off terminal and the Vi() terminal can be used to override the remote on/off.MC010-Series Power Modules; 18 Vdc to 36 Vdc Inputs, 10 W Design Considerations Remote On/Off Either the user-supplied switch or the override jumper should be wired into the circuit via individual traces not common with the Vi() power current path. Connect the switch or jumper at the power module terminals (see Figure 5). Configuring the switch connection in this way prevents noise from falsely triggering the remote on/off. Top view. Vile) Vi COMMON 0 CONNECTION POINT. ~ }+#______@ Se + REMOTE | Sa [ Voniot | ON/OFF lon/oft _ Figure 5. Remote On/Off Wiring Configuration Input Source Impedance The power module should be connected to a low-ac- impedance input source. Source impedances greater than 12 wH can affect the stability of the power mod- ule. When the source impedance exceeds 12 WH, mount a 33 uF electrolytic capacitor (ESR < 0.7 Q 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). Thermal Considerations Although the power module is designed for an 85 C maximum operating ambient temperature, the charac- terization 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. Varia- tions in local temperature and airflow, as well as the methods and location of measurement for these parameters, can affect the resulting internal tempera- ture rises for a given ambient temperature. For ambient temperatures exceeding 70 C, call 1-800-526-7819 for application assistance. 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. me 0050026 O02b0e3 ?ecMC010-Series Power Modules; 18 Vdc to 36 Vdc Inputs, 10 W Outline Diagrams Dimensions are in inches and (millimeters).
