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.
