Redefining “Current” Limits In Power Conversion
Up to 300W Half Bricks
The HBO PH series of low cost DC/DC converters offer the
different current levels and are comparable to existing half-
bricks. With a wide input voltage range of 18-24V or 36-75V
they are available with an output voltage of either 1.8, 2.5,
3.3, 5.0, 12, 15, 24 or 28 Volts. All models feature an input
filter, output overvoltage and overtemperature protection,
output current limiting and short circuit protection. The
unique open frame construction with base plate design
achieves efficient heat transfer with no hot spots. The use of
patented Flat 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.
