APPLICATIONS
83
Compared to standard 2 Watt packages,
space savings of 80% respectively 77% are
achieved by these 2A-NXT&2B-NXT SMD
Miniature DC/DC Converters. They have been
specifically designed for applications where
board space is at a premium,since these 2
Watt converters have only a slightly larger foot
print than conventional 1 Watt converters.
At efficiencies up to 80%, external cooling is
not needed, as the full output power is
available over the operating temperature
range -40°C to +85°C. All converters have an
I/O-Isolation of 1kVDC, allowing making them
suitable for many applications.
