APPLICATIONS

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.
