Redefining “Current” Limits In Power Conversion
40-50A High Efficiency Quarter Bricks
Description
The HQ series of high current, high efficiency DC/DC
converters offer current levels that exceed all other quarterbricks and are comparable to existing quarter-bricks. With a
wide input voltage range of 36-75V they are available with
an output voltage of either 1.5, 1.8, 2.5 or 3.3 Volts. All
models feature an input filter, input undervoltage lockout,
output overvoltage and overtemperature protection, output
current limiting and short circuit protection. The unique openframe 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 with the highest efficiency up to 91%. 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.
