PRODUCT DATA SHEET
DESCRIPTION
The PWR40XX Series offers a low-cost alternative for some
of the most popular DC/DC converters industry wide. Each
model has a high-isolation version and an outstanding
demonstrated MTTF of 5,000,000 hours at 25°C. The superior
reliability and low cost make it an excellent choice for industry
standard usages.
The series includes thirteen standard models (other input
and output voltages are available upon request), all set in a
flexible encapsulation material which has excellent thermal
dissipation and low mechanical stress on internal components.
The use of surface-mount devices and manufacturing
processes, combined with the encapsulation process, provides
the user a product that is environmentally rugged.
The PWR40XX has full isolation between input and output to
give the designer maximum flexibility in grounding options
and polarity configurations. The outputs are protected against
momentary short circuits.

APPLICATION NOTES
SHORT CIRCUIT PROTECTION
To maintain low cost, the PWR40XX Series provides limited
short-circuit protection. To protect against continuous short
circuits, a fuse is required. It is recommended that the fuse
be placed in series with the input of the converter. The
required I
2
t will vary with input voltage.
OUTPUT POWER
The PWR40XX series was designed to meet power require-
ments up to 4W. Due to the nature of unregulated power
supplies, a higher-than-rated output voltage will result when
less-than-rated power is used (see Typical Performance
Curves). This series has been designed to run from no load
to 4W without derating up to +70°C.
UNBALANCED LOADS
Unbalanced loads may be used on dual output models with
each side sourcing up to 200mA as long as the total power
out is not more than 4W. With an unbalanced load, the output
voltages will track within 5% of each other.
OUTPUT NOISE
The output noise can be reduced to less than 50mVp-p by
adding a low ESR 10µf tantalum capacitor across each
output.
