APPLICATIONS
Compared to standard 2 Watt packages,
space savings of 80% respectively 77% are
achieved by these A-NXT-2W&B-NXT-2W
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.
