The 1500HN, single output power modules are 12 to 15 watt
DC/DC converters 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, 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 89%. 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.
