The OPN20 series are non-isolation DC-DC converter packaged in a single-in-line footprint
(2.5 x 0.55 x 0.26 inch) giving designers a cost effective solution for conversion from 5VDC
to 3.3V, 2.5V, 2.1V, 1.8V and 1.5V and from 3.3VDC to 2.5V, 2.1V, 1.8V, 1.5V. This series
was designed for applications that include distributed power, workstations, computers and
servers.
