RB
Description
1 Watt
SIP7
Single and
Dual Output
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.
