“MRD-WRNI” Series

MAXIMUM OUTPUT POWER 4 WATTS Packaging Size: 1 x 2 x 5 inches
  • dual outputs
  • wide input voltage range
  • all outputs highly regulated under conditions of input voltage and output load. ¸ balance loading is not required to maintain regulation on either output. internal six-sided electrostatic shield
  • one continuous copper shield covers the entire electronics internally to provide a tight six-sided electrostatic shield
  • low output noise on all outputs
  • no overshoot during turn-on or load changes
  • 125 khz switching frequency
Input Voltage Range: 4.6 –7.2, 4.6 – 8, 7 – 11 or 9 –18 VDC
Output Voltages: -5 and +5 VDC
Output Voltage Setting Tolerance: ± 1% and ± 5%

Application information: The “MRD-WRNI” DC/DC Converters are designed for use in wide range input voltage applications such as battery inputs where high efficiency is of prime importance, however tradeoffs in design have been made to yield excellent regulations and low output ripple on each output individually, while still operating at high efficiency.

SSM Series

Ultra wide input voltage range with single, non-isolated, well regulated output

“SSM” Series
MAXIMUM OUTPUT POWER 6.6 - 36.0 WATTS Packaging Size: 1 x 2 x .5 inches

The SSM Series units have single, regulated and well-filtered outputs that are also short circuit protected. The unique circuiting employed in the SSM Series units provides a double-filtered, very low ripple and noise-regulated output while still maintaining a high efficiency. Units contain internal copper shielding and are fully encapsulated.
