The POWER-ONE SQM48T20018-NBA0 is a high-efficiency DC DC converter from the SQM48T/S20 family, designed for applications in telecommunications, data communications, wireless communications, and servers.
This converter operates with an input voltage range of 36-75 VDC and provides a nominal output voltage of 3.3 VDC at up to 20A. It features a high efficiency design that eliminates the need for a heat sink, and offers higher current capability at elevated temperatures compared to many competitors' 20-25A quarter-bricks.
The SQM48T20018-NBA0 utilizes an industry-standard quarter-brick pinout and is available in through-hole and SM packages. Its extremely small footprint measures 0.896” x 2.30” (2.06 in²), making it 38% smaller than conventional quarter-bricks. The low profile is only 0.28” (7.1 mm), and it weighs just 0.66 oz (18.5 g).
Key features include onboard input differential LC-filter for low input ripple current, start-up into pre-biased output, and no minimum load requirement. It meets Basic insulation requirements of EN60950, withstands 100 V input transient for 100 ms, and operates at a fixed frequency. The output voltage can be trimmed from +10% to -20% (except for the 1.2 V output). Reliability is high, with an MTBF of 3.4 million hours.
