APPLICATIONS

packages, space savings of 80% respectively 77% are achieved by these A-NXT& B-NXT SMD Miniature DC/DC Converters. They have been specifically designed for a premium,since these Watt converters have only a slightly larger foot print than conventional 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 All converters have an I/O-Isolation of 1kVDC, allowing maki ng them suitable for many applications.
