The 1000HN, dual output power modules are 10 watt DC/DC
converters featuring a 4 - 1 input range and available in a
dual output configuration providing both digital and analog
outputs in a compact, industry standard 1.0" X 2.0" X 0.375"
package. These 400kHz, switching converters are available
in 12, 24 and 48 VDC inputs making them one of the most
versatile product lines in the market with efficiencies up to
83%. Advanced surface mount construction allows these
converters to achieve outstanding thermal performance
eliminating the need for thermal potting compounds and
thereby enhancing manufacturing efficiency to reduce
costs.
