Sixteenth Brick Delivers 3.3V @ 25A and Exceptional Elevated-Temperature Performance
Power-One, Inc. introduces the SSQE48T25033 DC-DC Converter. This DOSA-compliant sixteenth brick provides 3.3 VDC @ 25 amps with 100% of full-rated power available at 55°C, and 22 amps @ 70°C, using only 200LFM airflow. Tight regulation (+/-3% combined line, load, and temperature), and efficiencies up to 93% make this an ideal DPA or IBA power source for communications, data server/storage, and workstation applications.
This rugged product also features the capability to withstand a 100V input transient for 100ms, meets EN 60950 Basic Insulation requirements, and is UL94 V-0 flammability rated. Additional features include: a wide-range 36 to 75 VDC input, the capability to start up into pre-biased loads, and no minimum-load operation.
Protections include: hiccup-mode overcurrent, output overvoltage, input undervoltage lockout, and overtemperature shutdown. Interface and trim capabilities include: remote sense, remote ON/OFF (positive or negative logic option), and +10%/−20% output voltage trim ranges with industry-standard trim equations. Approvals include: UL/CSA 60950-1, EN 60950-1, and IEC EN 60950-1.
A low-profile 0.374” (9.5mm) height reduces airflow shadowing, facilitating improved cooling for downstream components. The SSQE48T25033 features a DOSA-compliant through-hole-mount pinout and 0.9” x 1.3” (22.9mm x 33mm) footprint.
