Description
Power-One’s point-of-load converters are recommended for use with regulated bus converters in an Intermediate Bus
Architecture (IBA). T
he DM7300 is a fully programmable digital power manager that utilizes the industry-standard I
2
C
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
management and programming and monitoring of the dPwer
TM
POL converters and other industry standard power
and peripheral devices. Parameters of the DM7300 are programmable via the I
2
C bus and can be changed by a user at
any time during product development and deployment.
