RI3 3W SIP4 Single Output DC/DC Converters RECOM Power RI3 3W SIP4 Single Output DC/DC Converters are designed for applications where board space is at a premium. RECOM RI3 DC/DC Converters have the same footprint as RI 2W converters. Full output power is available with efficiencies up to 90% over the -40°C to +85°C operating temperature range. These converters can be used in ambient temperatures of up to +100°C with derating. The wide selection of input voltage and output voltage options plus an I/O-isolation of 1kVDC, 2kVDC, or 3kVDC makes these converters suitable for many industrial applications.
