DC to DC Converters
Distributed Power Supplies for Systems, Insulation Type
Half Brick Type iHA/iHD Series
Power supply systems for infrastructure devices used in communi-
cation networks primarily use brick-type DC to DC converters.
As the voltage used for LSIs continues to drop, power supplies are
expected to provide lower output, higher efficiencies, and lower
noise levels. Moreover, the high-power is needed in the mid output
voltage such as RF lamps.
To meet these demands, we have developed half brick types with
low output voltage.
FEATURES
• Wide input voltage range (DC.36 to 75V)
• There are 19 models in the lineup of products with low to
medium output voltages.
• High efficiency: 92%(5V and 28V output)
• Heat sink is not required.
• Remote ON-OFF function
• Output voltage external variable function
• Remote sensing function
• Various protective functions
• Parallel operations are available only for iHD type
