Description
Power-One’s point-of-load converters are recommended for use with regulated bus converters in an Intermediate
Bus Architecture (IBA). The ZM7300 is a fully programmable digital power manager that utilizes the
industry-standard I2C communication bus interface to control, manage, program and monitor up to 32 Z-
series POL converters and 4 independent power devices. The ZM7300 completely eliminates the need
for external components for power management and programming and monitoring of the Z-OneTM POL
converters and other industry standard power and peripheral devices. Parameters of the ZM7300 are
programmable via the I2C bus and can be changed by a user at any time during product development
and deployment.
