Eighth-Brick Series 2nd Generation IBC DC-DC CONVERTERS 200-300 W Intermediate Bus Converters 1 NEW Product • 48 V input with isolated 12 V output • Ultra-high efficiency, 95.5% 12 V @ 25 A • Unprecedented usable output power levels 3 • High power density (362 W/in ) open-frame technology • Wide operating ambient temperature range • Industry standard eighth-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 Eighth-Brick Intermediate Bus Converters (IBC) targeted specifically at the computer, industrial electronics, and telecommunications distrib- uted power markets. In a Distributed Power Arcitecture (DPA), these converters are intended to power multiple downstream non-isolated point-of-load (POL) converters. The elevated conversion efficiency, open-frame construction, and superior thermal performance of this series produces 3 rated output currents up to 25 A and power densities as high as 362 W/in . These superior per- formance levels enable these eight-brick models to replace quarter-brick and half-brick convert- Patent No. 6,765,810 ers in applications where footprint, profile, and cost are critical. The IBC25A fixed ratio model Other Patents Pending produces an unregulated 12 V output while the narrow and wide input IBC20A and IBC17A mod- els produce a 12 V output semi-regulated with line and load variations. All models are fully pro- tected against overcurrent, overvoltage, and overtemperature. A positive logic primary referenced remote ON/OFF input is included as standard with negative logic available as an option. 2 YEAR WARRANTY All specifications are typical at nominal input, full load at 25 °C ambient unless otherwise stated SPECIFICATIONS OUTPUT SPECIFICATIONS EMC CHARACTERISTICS Output setpoint accuracy See Table Immunity: ESD air enclosure EN61000-4-2 8 kV, 6 kV (air, contact) Line regulation Low line to high line See Table Input transients: IBC25AET4812 60 V, 100 ms IBC20AES4812 60 V, 100 ms Load regulation Full load to min. load See Table IBC17AEW4812 100 V, 100 ms Total error band IBC25AET4812 9.70-13.40 Vdc GENERAL SPECIFICATIONS (Including setpoint, line, IBC20AES4812 11.52-12.48 Vdc load and temperature) IBC17AEW4812 11.40-12.60 Vdc Efficiency See Table Minimum load 0 A Basic insulation Input/output 2250 Vdc Overshoot At turn-on and turn-off None Switching frequency Fixed 600 kHz typ.
