The 1000HN, single output power modules are 12 to 15 watt
DC/DC converters featuring a 4 - 1 input range and available
in a single output configuration providing 3.3 VDC to 15 VDC
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
87%. 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.
