Power-One SSQE48T20033: 16th-brick converter claims efficiency boost over to over 90%
Providing a 3.3V output voltage, the 20A SSQE48T20033 isolated dc/dc 16th-brick converter boosts power densities as high as 56W/in.2 and increases efficiency to more than 90% in communications, data/server/storage, and workstation applications. Features include onboard input differential-LC filtering, start-up into prebiased loads, a 10%/–20% output trim, a 36 to 75V input-voltage range, and the ability to withstand a 100V input transient for 100 msec. Interface capabilities include remote sense and remote on/off with a positive- or negative-logic option. The device also features overtemperature, output-overvoltage and -overcurrent, and input-undervoltage protection. Available with a 0.374-in. profile, the SSQE48T20033 costs $25 (1000).
