Dual Quarter-Brick DC/DC Converter
Since the QD48 converters utilize independent power trains and control functions for each output, they provide precise set points (± 1%) and extremely tight output voltage regulation for each output, ± 2% over all line, load, and temperature conditions. Cross-channel interference is virtually non-existent, even during load transients. Transient performance for each output is an order of magnitude better than competing dual quarter-bricks.
The QD48 converters come in an open-frame package that does not require a heatsink. They have dimensions of 1.45× 2.3 (36.8 mm × 58.4 mm), with a height as low as 0.26 (6.6 mm). They weigh 25.5 g (0.9 oz.), also the lowest in the industry. The surface mount version is shipped in tape-and-reel packing to facilitate automatic handling and pick-and-place assembly.
