BTCPower TM Broadband TelCom Power, Inc. SQO/SQ Series Redefining “Current” Limits In Power Conversion 25A High Efficiency Quarter Bricks Description The SQO/SQ series of high power density, high efficiency DC/DC converters deliver up to 25A in an industry standard quarter-bricks footprint. With a wide input voltage range of 36-75V they are available with an output voltage of either 1.5, 1.8, 2.5, 3.3 or 5 Volts. All models feature an input filter, input undervoltage lockout, output overvoltage and overtemperature protection, output current limiting and short circuit protection. These converters are available either in a package that is open-frame / enclosure construction. The aluminum heat spreader design achieves very efficient heat transfer with no hot spots. The use of highly derated power devices help to achieve high reliability, high performance and offer a low cost solution to systems designers that are challenged to maximize power and minimize board space.
