Description
• Micro size SIP 6 package
• Industry standard pinout
• Power sharing on dual output version
• 3kVDC/1s basic isolation
• Optional continuous short circuit protection
• Efficiency up to 84%
DC/DC Converter
RBM
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.

Notes:
Note1: Efficiency is tested at nominal input and full load at +25°C ambient
Note2: Max Cap Load is tested at nominal input and full resistive load and is defined as the
capacitive load that will allow start up in under 1s without damage to the converter
