DESCRIPTION
The MEF1 series of DC/DC converters is used
where a tightly regulated supply is required. They
are ideal for situations where the input voltage
is not tightly controlled. The single rail regulated
output makes the ideal choice to power sensors,
such as pressure transducers, hall effect sensors
and mass airflow sensors.
