2W dual output converter

Industry standard SIP7 packages

Power sharing on outputs

Optional continuous short circuit protection

1kVDC and 2kVDC basic isolation

UL94 V-0 package material

Efficiency up to 87%

DC/DC Converter

RD

The RD series have been specifically designed for applications where dual power rails need to

be created from a single rail supply and a low cost solution is required. With efficiencies up to 87%,

the full output power is available over the operating temperature range -40°C to +85°C and

the converters can be used in ambient temperatures of up to 100°C with derating. The wide selection

of industry standard input voltage and output voltage options plus an input to output isolation of 1kVDC

or 2kVDC makes these converters suitable for many industrial applications.
