Description

The RFB 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

1kVDC isolation, industrial operating temperature range of -40°C to +85°C without derating and

UL/EN certifications.

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

Single

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)
