Description

The DCPA1 series is a family of 1-W, isolated, unregulated DC/DC converter modules. Requiring a minimum of two external components, the DCPA1 series of devices include on-chip device protection, and the ability to synchronize to an external clock.

This combination of features and small size makes the DCPA1 series of devices suitable for a wide range of applications, and is an easy-to-use solution in applications requiring signal path isolation.

WARNING: This product has operational isolation and is intended for signal isolation only. It should not be used as a part of a safety isolation circuit requiring reinforced isolation. See definitions in the Feature Description section.
