The MEV series is the new high performance
version of our 1W NMV series. The MEV series
is more efficient and offers improved regulation
performance ≤5% for applications where a wide
output voltage variation can not be tolerated. They
are ideally suited for providing local supplies on
control system boards with the added benefit
of 3kVDC galvanic isolation to reduce switching
noise. The MEV series is currently available in an
industry SIP 7 package.

When operated with additional external load capacitance the rise time of the input voltage will determine the maximum external
capacitance value for guaranteed start up. The slower the rise time of the input voltage the greater the maximum value of the
additional external capacitance for reliable start up.
