DC-DC CONVERTERS
336-450 W Intermediate Bus Converters
NEW Product
1
48V input with isolated 12 V output
Ultra-high efficiency, 95.5% 12 V @ 37.5 A
Unprecedented useable output power levels
High power density (337 W/in
3
) open-frame technology
Wide operating ambient temperature range
Industry standard quarter-brick footprint and pinout
Low profile, 0.40 ” (10.2 mm)
Meets basic insulation requirements of EN60950-1
Remote ON/OFF and overtemperature protection
Available RoHS compliant
This is a new series of high power density low profile quarter-brick converters targeted
specifically at the computer, industrial electronics and telecommunications distributed
power markets. By virtue of the elevated conversion efficiency, open-frame
construction and superior thermal performance, the series produces rated output
currents up to 37.5 A and power densities as high as 337 W/in
3
. Given these
dominating performance levels, this quarter-brick implementation is a viable option for
replacing half-brick converters in applications where footprint, profile, and cost are
critical. The IBC38A fixed ratio model produces an unregulated 12 V output while the
narrow and wide input IBC30A and IBC28A models produce a 12 V output semi-
regulated with line and load variations. All models are fully non-latch protected against
overcurrent, undervoltage, overvoltage, and overtemperature. A positive logic primary
referenced remote ON/OFF input is included as standard, with negative logic available
as an option.
All specifications are typical at nominal input, full load at 25 °C ambient unless otherwise stated
