Description
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 the converter to be controlled by an external enable signal.
