Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute 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 the
device reliabiltiy.

CAUTION: This power module is not internally fused. An input line fuse must always be used.

This 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 time-delay 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 sheet for further information.

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., UL60950, CSA C22.2
No. 60950-00, and
VDE 0805:2001-12 (IEC60950, 3rd Ed).

These converters have been evaluated to the spacing
requirements for Basic Insulation, per the above safety stan­dards.

For Basic Insulation models ("–B" Suffix), 1500 Vdc is
applied from VI to VO to 100% of outgoing production.

For end products connected to –48 Vdc, or –60 Vdc nomianl
DC MAINS (i.e. central office dc battery plant), no further
fault testing is required.

Note:–60 V dc nominal bettery plants are not available in the

U.S. or Canada.
For all input voltages, other than DC MAINS, where the input
voltage is less than 60 Vdc, if the input meets all of the
requirements for SELV, then:

n

The output may be considered SELV. Output voltages will
remain withing SELV limits even with internally-generated
non-SELV voltages. Single component failure and fault
tests were performed in the power converters.

n

One pole of the input and one pole of the output are to be
grounded, or both circuits are to be kept floating, to main­tain the output voltage to ground voltage within ELV or
SELV limits.

For all input sources, other than DC MAINS, where the input
voltage is between 60 and 75 Vdc (Classified as TNV-2 in
Europe), the following must be adhered to, if the converter’s
output is to be evaluated for SELV:

n

The input source is to be provided with reinforced insula­tion from any hazardous voltage, including the AC mains.

n

One VI pin and one VO pin are to be reliably earthed, or
both the input and output pins are to be kept floating.

n

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.

The power module has ELV (extra-low voltage) outputs
when all inputs are ELV.

All flammable materials used in the manufacturing of these
modules are rated 94V-0, and UL60950A.2 for reduced
thicknesses. The input to these units is to be provided with a
maximum 5A time-delay in the unearthed lead.

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 input
source inductance exceeds 4 µH, a 33 µF electrolytic capaci­tor (ESR < 0.7 W at 100 kHz) mounted close to the power
module helps ensure stability of the unit.

Feature Descriptions

Remote On/Off

Two remote On/Off options are available. Positive logic
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 remote On/Off, device code suffix "1", turns
the module off during logic-high voltage and on during a logic
low.

To turn the power module on and off, the user must supply a
switch to control the voltage betw e en the
ON/OFF pin and the VI(–) terminal. The switch may be an
open collector or equivalent (see Figure 40). 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. During a logic high, the maximum Von/off
generated by the power module is 15 V. The maximum allow­able leakage current of the switch at Von/off = 15 V is 50 µA.

If not using the remote on/off feature, do one of the following:
For positive logic, leave the ON/OFF pin open.
For negative logic, short the ON/OFF pin to VI(–).

shown in the Feature Specifications table. This limit includes
any increase in voltage due to remote sense compensation
and output voltage set-point adjustment (trim) (See Figure

41). If not using the remote sense feature to regulate the out­put at the point of load, then connect SENSE(+) to VO(+) and
SENSE
(–) to VO(–) at the module.

Although the output voltage can be increased by both the
remote sense and by the trim, the maximum increase for the
output voltage is not the sum of both. The maximum increase
is the larger of either the remote sense or the trim.

The amount of power delivered by the module is defined as
the voltage at the output terminals multiplied by the output
current. When using remote sense and trim, the output volt­age of the module can be increased, which at the same out­put current would increase the power output of the module.
Care should be taken to ensure that the maximum output
power of the module remains at or below the maximum rated
power.

Feature Descriptions (continued)

Overcurrent Protection

To provide protection in an output overload fault condition,
the module is equipped with internal current-limiting circuitry,
and can endure current limiting for an unlimited duration. At
the instance of current-limit inception, the module enters a
"hiccup" mode of operation, whereby it shuts down and auto­matically attempts to restart. While the fault condition exists,
the module will remain in this mode until the fault is cleared.
The unit operates normally once the output current is
reduced back into its specified range.

Output Overvoltage Protection

The output overvoltage protection consists of circuitry that
monitors the voltage of the output terminals. If the output volt­age exceeds the overvoltage protection threshold, the mod­ule enters a "hiccup" mode of operation, whereby it shuts
down and automatically attempts to restart. While the fault
condition exists, the module will remain in this hiccup mode
until the overvoltage fault is cleared.

Overtemperature Protection

The output overvoltage protection consists of circuitry that
monitors the voltage on the output terminals. If the output
voltage exceeds the overvoltage protection threshold, the
module enters a "hiccup" mode of operation, whereby it shuts
down and automatically attempts to restart. While the fault
condition exists, the module will remain in this hiccup mode
until the overvoltage fault is cleared.

Input Undervoltage Lockout

At input voltages below the input undervoltage lockout limit,
the module operation is disabled. The module will begin to
operate at an input voltage above the undervoltage lockout
turn-on threshold.

Thermal Considerations

Determine airflow (v) (Use Figure 52)

v = 0.5 m/s (100 ft./min.)

The power modules operate in a variety of thermal environ­ments; however, sufficient cooling should be provided to help
ensure reliable operation of the unit. Heat is removed by con­duction, convection, and radiation to the surrounding environ­ment. Proper cooling can be verified by measuring drain pin
of Q560 or of Q10 at the position indicated in Figure 44.

The temperature at Q560 and Q10 drain pins should not
exceed 110 °C. The output power of the module should not
exceed the rated power for the module
(VO, set x IO, max).

power modules is 85 °C, you can limit this temperature to a

The RoHS-compliant through-hole products use the SAC
(Sn/Ag/Cu) Pb-free solder and RoHS-compliant components.
They are designed to be processed through single or dual
wave soldering machines. The pins have an RoHS-compli­ant finish that is compatible with both Pb and Pb-free wave
soldering processes. A maximum preheat rate of 3°C/s is
suggested. The wave preheat process should be such that
the temperature of the power module board is kept below
210°C. For Pb solder, the recommended pot temperature is
260°C, while the Pb-free solder pot is 270°C max. Not all
RoHS-compliant through-hole products can be processed

for dry packed SMT packages will be a minimum of 12
months from the bag seal date, when stored at the following
conditions: < 40° C, < 90% relative humidity.

Post Solder Cleaning and Drying Considerations

Post solder cleaning is usually the final circuit-board
assembly process prior to electrical board testing. The result
of inadequate cleaning and drying can affect both the
reliability of a power module and the testability of the finished
circuit-board assembly. For guidance on appropriate
soldering, cleaning and drying procedures, refer to Tyco
Electronics Board Mounted Power Modules: Soldering and
Cleaning Application Note (AP01-056EPS).

Solder Ball and Cleanliness Requirements

The open frame (no case or potting) power module will meet
the solder ball requirements per J-STD-001B. These require­ments state that solder balls must neither be loose nor violate
the power module minimum electrical spacing.
The cleanliness designator of the open frame power module

is C00 (per J specification).
