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 25C. 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 I2 t will vary with input voltage. OUTPUT POWER The PWR40XX series was designed to meet power requirements 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 +70C. 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 10f tantalum capacitor across each output.
