Description
The RB series DC/DC converter has been designed for isolating or converting DC power rails in
general purpose applications. Although low cost, it does not compromise on features and offers
1KVDC/1s or 2kVDC/1s isolation, a –40°C to +85°C operating temperature range and optional
continuous short circuit protection.

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
