HQ40A-48

The HQ40A-48 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 HQ40A-48 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.
