Description
The HLS Series of high density, single-output dc-dc converters, convert standard telecom and datacom voltages
into isolated low-voltage outputs. High efficiencies and a unique copper-core printed circuit board design create
superior thermal characteristics that enhance product reliability and eliminate the need for a heat sink.
