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 out-
puts. The outputs are isolated from the input, allowing versatile polarity configurations and grounding connec-
tions. 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 fil-
tering.

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.

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, 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.

Current Limit
Design Considerations
Input Source Impedance
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
tailout characteristics (output-current decrease or
increase). The unit operates normally once the output
current is brought back into its specified range.
The power module should be connected to a low
ac-impedance input source. Highly inductive source
impedances can affect the stability of the power mod-
ule. 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
Remote On/Off (Optional)
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.
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 dur-
ing a logic high and on during a logic low.
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:
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 may be an open collector or equivalent (see
Figure 38). A logic low is Von/off = –0.7 V to +1.2 V. The
maximum Ion/off during a logic low is 1 mA. The switch
should maintain a logic-low voltage while sinking 1 mA.
n All inputs are SELV and floating, with the output also
floating.
n All inputs are SELV and grounded, with the output
also grounded.
During a logic high, the maximum Von/off generated by
the power module is 10 V. The maximum allowable
leakage current of the switch at Von/off = 10 V is 50 µA.
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 reli-
ability test performed on it in combination with the
converters.
The module has internal capacitance to reduce noise
at the ON/OFF pin. Additional capacitance is not gen-
erally needed and may degrade the start-up character-
istics of the module.
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.

Output Overvoltage Clamp
REMOTE
ON/OFF
Ion/off
The output overvoltage clamp consists of control cir-
cuitry, independent of the primary regulation loop, that
monitors the voltage on the output terminals. This con-
trol loop has a higher voltage set point than the primary
loop (see Feature Specifications table). In a fault condi-
tion, the overvoltage clamp ensures that the output
voltage does not exceed VO, clamp, max. This provides a
redundant voltage-control that reduces the risk of
output overvoltage.

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 exter-
nal resistor between the TRIM pin and either the VO(+)
or VO(–) pins. With an external resistor between the
TRIM and VO(+) pins (Radj-down), the output voltage set
point (VO, adj) decreases (see Figure 39). The following
equation determines the required external resistor
value to obtain an output voltage change from VO, nom

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 addi-
tion, 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).

With an external resistor connected between the TRIM

obtain an output voltage from VO, nom to VO, adj:
With external circuitry, the unit is capable of synchroni-

Heat Transfer Characteristics
Thermal Considerations
Increasing airflow over the module enhances the heat
transfer via convection. Figures 43 through 45 show
the maximum power that can be dissipated by the mod-
ule without exceeding the maximum case temperature
versus local ambient temperature (TA) for natural con-
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 ther-
mally coupled to the case. Heat is removed by conduc-
tion, convection, and radiation to the surrounding
environment. Proper cooling can be verified by mea-
suring the case temperature. The case temperature
(TC) should be measured at the position indicated in
Figures 41 and 42.

Systems in which these power modules are used typi-

components in the system. Therefore, the natural con-
