Description
The MCO10A, B, C, BK, and CL Power Modules are dc-dc converters that operate over a wide input voltage range of 18 Vdc to 36 Vdc and provide precisely regulated dc outputs. 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 full-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. 1

extended periods can adversely affect device reliability. Specifications apply to all devices. Table 1. Input Specifications CAUTION: This power module is not internally fused. An input line fuse must always be used. fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. rating of the fuse must not exceed 5 A. Refer to the fuse manufacturer's data for further information.

MC010-Series Power Modules; Output Overvoltage Clamp Remote On/Off (MCO10A1, B1, C1, BK1, and CL1 only) The output overvoltage clamp consists of control circuitry, which is independent of the primary regula- To turn the power module on and off, the user must tion loop, that monitors the voltage on the output supply a switch to control the voltage between the on/ terminals. The control loop of the clamp has a higher off terminal and the Vi(--) terminal (Vorot). The switch voltage set point than the primary loop (see Feature can be an open collector or equivalent (see Figure 5). Specifications table). This provides a redundant volt- A logic low is Vonot = 0 V-to 1.2 V, during which the age-control that reduces the risk of output overvoltage. module is on. The maximum lonott during a logic low is 1 mA. The switch should maintain a logic low voltage i. while sinking 1 mA. Current Limit During a logic high, the maximum Von/ot generated by To provide protection in a fault (output overload) the power module is 18 v. The maximum allowable condition, the unit is equipped with internal current- leakage current of the switch at Voniot = 18 V is 50 HA. limiting and can endure current limiting for an unlimited Note: A PWB trace between the on/off terminal and duration. At the point of current-limit inception, the unit the Vi(-) terminal can be used to override the shifts from voltage control to current control. If the remote on/off. 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. WM 005002b O0eb0e2 4%b 7
