Artesyn Technologies Inc. has launched two series of application-optimized intermediate bus dc/dc power converters that are designed primarily for powering multiple downstream non-isolated point-of-load converters.

The Typhoon IBCs are offered in two versions to address both telecom and datacom input voltage standards with efficiencies of 94 percent and 96 percent. The intermediate voltage bus generated by an IBC is used to power highly efficient downstream non-isolated point-of-load converters. By dispensing with much of the output regulation circuitry, IBCs are less expensive than conventional brick converters, and can yield a cost/Watt figure less than one half that of a brick.

For telecom and central office applications operating from 48V battery plants, the company has introduced a wide-input IBC capable of operating from any voltage in the range 36V to 75V. Implemented on a quarter-brick form factor, the 175W IBC generates a 12V intermediate bus voltage and can deliver up to 14A output current with a conversion efficiency of 94 percent. It employs an open- frame, single board construction and operates over a -40C to 100C temperature range, without the need for a heatsink. The converter combines an industry-standard quarter-brick pin-out with an installed height of 9mm.

All products feature remote on/off, and are comprehensively protected against input under-voltage, output over-voltage and over-current, and over- temperature conditions. In OEM quantities of 1,000, unit prices are $53.99 for the 14A wide-input and 20A narrow-input IBCs, and $59.39 for the 25A narrow-input IBC.
