200WATTS - NEW POWER
BREAKTHROUGH FOR QUARTER-BRICK DC/DC CONVERTERS
UP TO 100A IS NOW AVAILABLE FROM A SINGLE MODULE MEASURING A MERE 7.6mm IN HEIGHT WITH A
LOW 58.4 x 36.8mm SURFACE AREA!
Other highlights: fully regulated output voltage, efficiency of up to 92%, and an
unmatched power density of 12.2W/cm³!
The new 200W "Ultra" series is the latest addition to the highly innovative
TYPHOON product family, and it marks another world's first on the DC/DC converter front
for ARTESYN. The new quarter-bricks offer up to a 50% improvement in power capacity over
their present market competition, which makes them an extremely cost-effective functional
replacement for half-brick solutions. Occupying 40% less board space, they also feature
significantly higher output current levels and efficiency.
The "Ultra" series 200W quarter-bricks feature a wide telecom-standard input
voltage range of 36 to 75VDC and generate a single isolated output voltage that can be
trimmed from 80% to 110% of the nominal value using a single resistor.

The patented conversion topology is
the same as that used by all other Typhoon converters, combining advanced processor
control of both primary- and secondary-side circuitry with precision synchronous
rectification, and doing away with the need for optocouplers. This topology helps maximize
efficiency and bandwidth, which results in excellent regulation and transient response
characteristics.
The 60/80/100A devices have also adopted the new high-current, industry-standard pinout
option referred to as "The double P" (Thermally Enhanced Double Power Pins). It
includes an additional set of power and ground pins for sharing the current flow.
Their exceptionally high current, efficiency and power density attributes, in combination
with their low-profile footprint, make them ideal for delivering the 200W power
requirements of fully specified cards in AdvancedTCA® applications.
Unlike intermediate bus converters (IBCs) and DC-DC transformers, which only achieve high
efficiencies and power levels by generating loosely regulated or unregulated outputs,
ARTESYN's new 200W quarter-bricks feature fully regulated outputs for driving low-voltage
processor loads directly. All five converters have a set-point accuracy of ±1.5% and
maintain line and load regulation to within ±0.1% and ±0.2% respectively.
Primarily intended for use in forced air environments, they operate over a wide ambient
temperature range of -40 to +85?C and do not require a heatsink.
The converters offer differential remote sense and remote on/off facilities, and have a
typical start-up time of 10ms when driving a resistive load. They also feature
undervoltage lockout, as well as non-latching overvoltage protection, and are
comprehensively protected against short-circuit and overtemperature conditions, with
automatic recovery. The converters carry a full set of international safety approvals,
including UL/cUL60950 and EN60950-1 VDE. They also meet the rigorous EN61000-4-6 EMC
standard for conducted emissions and the telecom-standard input transient rating of 100V
for 100ms, which is beneficial in reducing customers' system qualification time and
accelerating their time-to-market.
