Description
Compared to standard 2 Watt packages, space savings of 80% respectively 77% are achieved by these RTS
& RTD 2 Watts 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 conven-
tional 1 Watt converters.
At efficiencies up to 80%, external cooling is not needed, as the full output power is available over the ope-
rating temperature range -40°C to +85°C. All converters have an I/O-Isolation of 1kVDC, allowing making
them suitable for many applications.
