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

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 standalone operation to an integrated part
of sophisticated power architectures. 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 fast-acting 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.

Design Considerations

Input Filtering

The power module should be connected to a low
ac-impedance source. Highly inductive source
impedance can affect the stability of the power module.
For the test configuration in Figure 7 a 33-100μF
electrolytic capacitor (ESR<0.7 at 100kHz), mounted
close to the power module helps ensure the stability of
the unit. Consult the factory for further application
guidelines.

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.
UL60950-1, CSA C22.2 No.60950-1, and VDE0805­1(IEC60950-1).

If the input source is non-SELV (ELV or a hazardous
voltage greater than 60 V

), for the module’s output to be considered as

75V

dc

meeting the requirements for 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,
including the ac mains.

 One V

pin and one V

IN

both the input and output pins are to be kept
floating.

 The input pins of the module are not operator

accessible.

 Another SELV reliability test is conducted on the

whole system (combination of supply source and
subject module), as required by the safety agencies,
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.

All flammable materials used in the manufacturing of
these modules are rated 94V-0, or tested to the UL60950
A.2 for reduced thickness.

For input voltages exceeding 60 V
equal to 75 V

, these converters have been evaluated to

dc

the applicable requirements of BASIC INSULATION
between secondary DC MAINS DISTRIBUTION input
(classified as TNV-2 in Europe) and unearthed SELV
outputs.

The input to these units is to be provided with a
maximum 5 A fast-acting fuse in the ungrounded input
lead.
