Vicor Corp.'s IBC050
series of wide input range VI BRICK Bus Converters are available as drop-in
upgrades for industry standard 5:1 and 4:1 converters. The new eighth and quarter
bricks achieve up to 98 percent efficiency from a 36 to 60V input voltage range
at power levels of up to 650W. With its wider input range, the IBC050 series
also provides 2,250V dc isolation from input to output.
The wider input range complies
with ETSI EN300 132-2 for -48V telecom applications requiring 5:1 or 4:1 bus
conversion from input voltages 36 to 60V. The higher input-to-output isolation
complies with IEEE 802.3 Power-over-Ethernet (PoE) standards. Owing to their
low effective output resistances, IBC050 series modules support output bus
voltages of 7 to 12V (5:1) or 8.7 to 15V (4:1) over the line and load range.
IBC050 series modules use Vicor's Sine Amplitude Converter topology and are pin-compatible.
The new VI BRICK Bus
Converters use the ZCS/ZVS resonant converter technology.† Switching at
approximately 10 times the frequency of square wave converters, IBC050 modules
cut transient response time by a factor of 10, eliminating the need for external
bulk capacitors. Power density and conversion efficiency are useful for OEMs
seeking to maximize performance across a range of applications, including
telecommunications, computing, data storage, networking and
