Despite their "eighth brick" designation, most eighth-brick dc-dc converters measure about 2.3 by 0.9 in., making them just 40% smaller than their quarter-brick ancestors. But with its 2.3- by 0.725-in. footprint, the Xena 50 eighth brick from Ascom Energy Systems is exactly half the size of the quarter brick. That will allow two eighth bricks to fit in a quarter-brick slot. The Xena 50 delivers up to 30 A at 1.5 V.
