Eighth-Brick Series | 100 W DC-DC
High Efficiency, High Current, Low Profile DC-DC Converters
EIGHTH-BRICK SERIES
Single Output Ultra Products
High efficiency topology and high output current
Low profile, 0.300 in (7.62 mm) height
Industry standard eighth-brick footprint (identical to quarter-brick pinout)
38% savings in space over industry standard quarter-brick converters
Wide operating ambient temperature range, -40 °C to +85 °C
80% to 110% output trim
Basic insulation, 2250 Vdc
Overvoltage and overtemperature protection
Remote ON/OFF
Approvals to EN60950-1 VDE and UL/cUL60950
100 V, 100 msec input voltage transients rated
Monotonic startup into normal and prebiased loads
Secondary side control, no optocouplers, fast transient response
Available RoHS compliant
The Eighth-Brick Ultra series is a new
100 W, low cost, high efficiency, open
frame, isolated converter in an industry
standard eighth-brick footprint and
operates from a 36 Vdc to 75 Vdc supply.
This new series elevates the power density
threshold for high-end application design
requirements where high output current at
low voltages are required. The converter
architecture takes advantage of open-
frame construction to provide low mass
and a low thermal impedance for a single
board design.
Additionally, a patent pending, full wave
coupled inductor topology yields some of
the highest full load efficiencies in the
industry. All Eighth-Brick converters have,
as standard features, remote ON/OFF
capability, adjustable output voltage trim
from 80% to 110% of nominal, over-
current/under-voltage protection, and full
international safety approval including
EN60950-1 VDE and cUL60950.
