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.
