Redefining “Current” Limits In Power Conversion
48Vin
Dual Output 15/15A Half Bricks
The HB75D-48 series of low cost DC/DC converters offer the
different current levels and are comparable to existing
quarter-bricks. With a wide input voltage range of 36-75V
they are available with Dual output voltages of either 5.0/3.3
or 5.0/2.5 Volts. All models feature an input filter, output
overvoltage and overtemperature protection, output current
limiting and short circuit protection. The unique frame
construction with aluminum heat spreader design achieves
efficient heat transfer with no hot spots. The use of patented
Flat Matrix Transformer technology and other patent-pending
design concepts facilitate maximum power delivered. The
converters combine creative design concepts with highly
derated power devices to achieve very high reliability, high
performance and offer a low cost solution to systems
designers that are challenged to maximize power and
minimize board space.
