The RY series DC/DC converter is a low cost general purpose isolated converter with a
built-in linear regulator to give a regulated, load-independent output. It is available with
single or dual outputs. A useful feature is the CTRL pin on the single output version which
allows to controll the converter with an external enable signal.

RY
Series
Maximum capacitive load is defined as the capacitive load that will allow start up in under 1 second without damage to the converter
The RY series requires a minimum of 10% load on the output to maintain specified regulation. Operating under no-load conditions
will not damage these devices; however, they may not meet all listed specifications.
