Description
The RBM Micro Size DC/DC-Converter complements Recom’s industrial range of converters. This range is
widely used for pcb distributed power systems and combines small package size, high efficiency, 3kVDC
isolation and low output ripple.
The extended operating temperature range covering –40°C to +85°C is a standard feature. The full rated
power can be taken from a single pin of this dual output converter, provided this does not exceed 1 Watt.
