Description
The L Single- and Dual-Output-Series Power Modules are low-profile, dc-dc converters that operate over an
input voltage range of 18 Vdc to 36 Vdc or 36 Vdc to 75 Vdc and provide one or two precisely regulated outputs. The outputs are isolated from the input, allowing versatile polarity configurations and grounding connections. The modules have a maximum power rating of 10 W to 15 W and efficiencies of up to 84% for a 5 V
output and 82% for a 3.3 V output. Built-in filtering for both input and output minimizes the need for external filtering.

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 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, dc fuse with a maximum rating of 5 A (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.

18 Vdc to 36 Vdc or 36 Vdc to 75 Vdc Inputs, 10 W and 15 W
Design Considerations
Input Source Impedance
The power module should be connected to a low
ac-impedance input source. Highly inductive source
impedances can affect the stability of the power module. If the source inductance exceeds 4 µH, a 33 µF
electrolytic capacitor (ESR < 0.7 Ω at 100 kHz)
mounted close to the power module helps ensure
stability of the unit.
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 22.2 No. 950-95, EN60950, and
IEC950.
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), one of
the following must be true of the dc input:
n All inputs are SELV and floating, with the output also
floating.
n All inputs are SELV and grounded, with the output
also grounded.
n Any non-SELV input must be provided with rein-
forced insulation from any other hazardous voltages,
including the ac mains, and must have a SELV reliability test performed on it in combination with the
converters.
The power module has extra-low voltage (ELV) outputs
when all inputs are ELV.
Current Limit
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.
Remote On/Off (Optional)
Two remote on/off options are available. Positive logic,
device code suffix “4”, remote on/off turns the module
on during a logic-high voltage on the remote ON/OFF
pin, and off during a logic low. Negative logic, device
code suffix “1”, remote on/off turns the module off during a logic high and on during a logic low.
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 V
switch may be an open collector or equivalent (see
Figure 38). A logic low is V
maximum I
on/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 V

Output Voltage Adjustment (Optional on
Single-Output Units)
Output voltage set-point adjustment allows the user to
increase or decrease the output voltage set point of a
module. This is accomplished by connecting an external resistor between the TRIM pin and either the V
O(–) pins. With an external resistor between the
or V
TRIM and V
point (V
O(+) pins (Radj-down), the output voltage set
O, adj) decreases (see Figure 39). The following
equation determines the required external resistor
value to obtain an output voltage change from V
The combination of the output voltage adjustment
and the output voltage tolerance cannot exceed 110%
(125% for the D) of the nominal output voltage between

and L are shown in the following table:
The L-Series power modules have a fixed current-limit
set point. Therefore, as the output voltage is adjusted
down, the available output power is reduced. In addition, the minimum output current is a function of the
output voltage. As the output voltage is adjusted down,
the minimum required output current can increase
(i.e., minimum power is constant).
Synchronization (Optional)
With external circuitry, the unit is capable of synchronization from an independent time base with a switching
rate of 256 kHz. Other frequencies may be available;
please consult the factory for application guidelines
and/or a description of the external circuit needed to
use this feature.

Thermal Considerations
The power module operates in a variety of thermal
environments; however, sufficient cooling should be
provided to help ensure reliable operation of the unit.
Heat-dissipating components inside the unit are thermally coupled to the case. Heat is removed by conduction, convection, and radiation to the surrounding
environment. Proper cooling can be verified by measuring the case temperature. The case temperature

the maximum power that can be dissipated by the module without exceeding the maximum case temperature

Systems in which these power modules are used typically generate natural convection airflow rates of

Module Derating
The derating curves in Figures 43 through 45 were
determined by measurements obtained in an experimental apparatus shown in Figure 61. Note that the
module and the printed-wiring board (PWB) that it is
mounted on are both vertically oriented. The passage
has a rectangular cross section.

Outline Diagram
Dimensions are in millimeters and (inches).
Tolerance: x.x ± 0.5 mm (0.020 in.); x.xx ± 0.38 mm (0.015 in.).
If slightly lower height is needed, the four standoffs can be dropped through holes on the user’s PWB. By dropping
the standoffs through the PWB, the module height will be decreased to 9.5 mm (0.375 in.) typical height.
