Description
1 Watt
The RB series DC/DC converter has been designed for isolating or converting DC power rails in
SIP7
general purpose applications. Although low cost, it does not compromise on features and offers
1KVDC/1s or 2kVDC/1s isolation, a 40C to +85C operating temperature range and optional
continuous short circuit protection.
