MIC28303
The safe operating area (SOA) of the MIC28303 is
shown in the first three graphs of the Typical
Characteristics section. These thermal measurements
were taken on the MIC28303 evaluation board.
Because the MIC28303 is an entire system comprised
of switching regulator controller, MOSFETs and
inductor, the part needs to be considered a system.
The SOA curves will provide guidance for reasonable
use of the MIC28303.
5.8 Emission Characteristics of
MIC28303
The MIC28303 integrates switching components in a
single package, so the MIC28303 has reduced
emission compared to a standard buck regulator with
external MOSFETS and inductors. The radiated EMI
scans for MIC28303 are shown in Section 2.0, Typical
Performance Curves. The limit on the graph is per
EN55022 Class B standard.
