PRODUCT OVERVIEW
The MEA series is the new high performance
version of our 1W NMA series. The MEA 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 dual rail supplies
with the added benefit of galvanic isolation to
reduce switching noise. All of the rated power
may be drawn from a single output providing the
total load does not exceed 1 watt.
1. See Ripple & Noise characterisation method.
2. Calculated using MIL-HDBK-217F FN2 with nominal input voltage at full load.
All specifications typical at T
A
=25°C, nominal input voltage and rated output current unless otherwise specified.
