Description

Power-One’s point-of-load converters are recommended for use with regulated bus converters in an Intermediate Bus

Architecture (IBA). T

communication bus interface to control, manage, program and monitor up to 32 dP-series POL converters and 4

independent power devices.

The DM7300 completely eliminates the need for external components for power

any time during product development and deployment.
