Description
The ME005-Series Power Modules are dc-dc converters that operate over an input voltage range of 39.5 Vdc to
60 Vdc and provide precisely regulated dc outputs. The outputs are fully isolated from the inputs, allowing ver-
satile polarity configurations and grounding connections. The modules have maximum power ratings of 5 W at
typical full-load efficiencies of 80% to 83% depending on the code.
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.

ME005-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 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.

Test Configurations

Note: Input reflected-ripple current is measured with a simulated
source impedance of 12 µH. Capacitor C
S offsets possible
battery impedance. Current is measured at the input of the
module.

Note:Use a 0.1 µF ceramic capacitor. Scope measurement should
be made using a BNC socket. Position the load between
50 mm and 75 mm (2 in. and 3 in.) from the module.

Design Considerations
Input Reflected Ripple
An internal aluminum electrolytic input capacitor is
used for filtering; therefore, input ripple increases as
temperature decreases. There is approximately two
times more ripple at 0 °C than at 25 °C and eight times
more ripple at –40 °C than at 25 °C. The power module
functions properly down to –40 °C with no additional fil-
tering. If ripple comparable to that at 25 °C is needed at
low temperatures, an external capacitor across the
input with an impedance of 0.5 Ω at 100 kHz over the
desired temperature range is recommended.
Output Voltage 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).
If the input source is non-SELV (ELV or a hazardous
voltage greater than 60 Vdc and less than or equal to
75 Vdc), for the module's output to be considered
meeting the requirements of safety extra-low voltage
(SELV), all of the following must be true:
■The input source is to be provided with reinforced
insulation from any other hazardous voltages, includ-
ing the ac mains.
■One VI pin and one V O pin are to be grounded or
both the input and output pins are to be kept floating.
■The input pins of the module are not operator acces-
sible.
■Another SELV reliability test is conducted on the
whole system, as required by the safety agencies, on
the combination of supply source and the subject
module to verify that under a single fault, hazardous
voltages do not appear at the module's output.
Note: Do not ground either of the input pins of the
module without grounding one of the output
pins. This may allow a non-SELV voltage to
appear between the output pins and ground.
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 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
circuitry and can endure current limiting for an unlim-
ited 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 tai-
lout characteristics (output current decrease or
increase). The unit operates normally once the output
current is brought back into its specified range.
Output Overvoltage Protection
The output overvoltage clamp consists of control cir-
cuitry, 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.
