SIP20C Series

Single output

The SIP20C series are non-isolated dc-dc converters packaged in a single-in-line footprint

(2.5 x 0.55 x 0.23 inches) giving designers a cost effective solution for conversion of 5 Vdc to

3.3 Vdc and lower voltages. The SIP20C offers a best-of-class wide output trim range which

allows maximum design flexibility and a pathway for future upgrades. Local voltage

conversion by the SIP20C from existing 5 V system voltages eliminates the need for redesign

of existing power architectures when voltage requirements change. The SIP20C is designed

for applications that include distributed power, workstations, computers and file servers.

Implementing state of the art surface mount technology and automated manufacturing

techniques, the SIP20C offers compact size and efficiencies of 90%. The SIP20C is an

updated version of the original SIP20 and is fully compatible with the original model.

All specifications are typical at nominal input, full load at 25 °C unless otherwise stated
