ESCRIPTIONS
The 1500HN, dual output power modules are 15 watt DC/DC
converters available in a dual output configuration provid-
ing both digital and analog outputs in a compact, industry
standard 1.0" X 2.0" X 0.375" package. These 400kHz, switch-
ing 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 85%. Advanced surface
mount construction allows these converters to achieve
outstanding thermal performance eliminating the need for
thermal potting compounds and thereby enhancing manu-
facturing efficiency to reduce costs.
