Description

The RFMM DC/DC converter is typically used in cost sensitive general purpose power isolation and

voltage matching applications. Despite its low cost, it is a fully speciﬁed converter with

4kVDC isolation, industrial operating temperature range of -40°C to +85°C without derating and

UL/EN certiﬁcations.

Notes:

Note3: Operation below 10% load won‘t harm the converter, but speciﬁcations may not be met

Note4: Measurements are made with a 100nF MLCC across output (low ESR)
