Description
0.25 Watt
SIP4
The RM series DC/DC converter has been designed for isolating or converting DC power rails with very
light loads. Efficiencies are typically 10% higher than a comparable 0.5W or 1W converters run at the
same low load.

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
