RB/E
Description
The RB/E series is an unregulated DC/DC converter in standard SIP7 package style. This series has been
designed to offer exceptionally high efficiency at low loads, an extended operating temperature range
and low deviation (10% to 100%). Uses include applications with restricted energy budget and industrial
applications where a high efficiency level is required.

Model Numbering
Notes:
Note3: standard part is without continuous short circuit protection
add suffix „/P“ for continuous short circuit protection
Note4: add suffix „/H“ for 2kVDC isolation
or add suffix „/HP“ for 2kVDC isolation and continuous short circuit protection
Ordering Examples:
RB-1205S/E: 12VDC Input Voltage, 5VDC Output Voltage, Single Output
RB-3.305S/EP: 3.3VDC Input Voltage, 5VDC Output Voltage, Single Output with continuous short circuit protection
RB-0505S/EH: 5VDC Input Voltage, 5VDC Output Voltage, Single Output with 2kVDC isolation

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
