Description
The MC010-Series P o wer Modules are dc-dc con v erters 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 g rounding connections. The modules ha v e maximum po wer 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 envi-
ronment, the modules are rated to full load at 85 °C with no heat sinking or external filtering.
For applications requiring remote on/off, the MC010A1, B1, C1, BK1, and CL1 Power Modules are available.
These modules are equiv alent to the previously described modules, e xcept for the addition of the remote on/off
and associated terminal.

MC010-Series Power Modules:
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute 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.
Electrical Specifications
Unless otherwise indicated, specifications apply to all devices over all operating input voltage, resistive load, and
temperature conditions.
Table 1. Input Specifications
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 fus-
ing 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 Con-
siderations 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. However, for
UL
recognition, the dc rating of the
fuse must not exceed 5 A. Refer to the fuse manufacturer’s data for further information.

Design Considerations
Input Source Impedance
The power module should be connected to a low-ac-
impedance input source. Source impedances greater
than 12 µH can aff ect the stability of the pow er module.
When the source impedance exceeds 12 µH, mount a
33 µF electrolytic capacitor (ESR < 0.7 Ω at 100 kHz)
close to the module input pins. This is also recom-
mended to minimize reflected-ripple current as well as
conducted and radiated electromagnetic interference
(EMI).
Output V oltage Reversal
CAUTION: Applying a reverse voltage across the
module output forward biases an inter-
nal diode. Attempting to start the mod-
ule 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.
The power module has extra-low v oltage (ELV) outputs
when all inputs are ELV.
The input to these units is to be provided with a maxi-
mum 5 A normal-blow fuse in the ungrounded lead.
Feature Descriptions
Overcurrent Protection
To provide protection in a fault (output overload) condi-
tion, the unit is equipped with internal current-limiting
and can endure current limiting for an unlimited dura-
tion. At the point of current-limit inception, the unit
shifts from voltage control to current control. If the out-
put 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 On/Off
(MC010A1, B1, C1, BK1, and CL1 only)
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 Fig-
ure 5). A logic low is Von/off = 0 V to 1.2 V, during which
the module is on. 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 18 V. The maximum allowable
leakage current of the switch at Von/off = 18 V is 50 µA.
Note: A PWB trace between the on/off terminal and the
VI(–) terminal can be used to override the 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(–) po wer current path. Connect the
switch or jumper at the power module terminals (see
Figure 5). Configuring the switch connection in this w ay
pre vents noise from falsely triggering the remote on/off.

18 Vdc to 36 Vdc Input; 10 W December 1999
Feature Descriptions (continued)
Output Overvoltage Protection
The output overvoltage clamp consists of control cir-
cuitry, independent of the primary regulation loop, that
monitors the voltage on the output terminals. The con-
trol 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.
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 maxi-
mum operating ambient temperature for the module is
based on the maximum safe operating temperature of
the devices contained inside it. Variations in local tem-
perature and airflow, as well as the methods and loca-
tion 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.
