Power-One’s point-of-load converters are recommended for use with regulated bus converters in an Intermediate Bus
Architecture (IBA). The DM7300 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 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 dPwerTM POL converters and other industry standard power
and peripheral devices. Parameters of the DM7300 are programmable via the I2C bus and can be changed by a user at
any time during product development and deployment.

1 Writing into memory locations beyond address offset 0x96 must be avoided
The static registers are saved in the non-volatile memory and used to store the system configuration data. The run-
time registers contain status information and are evaluated during run-time. The Write Protection register WP is a
volatile register that defaults to write protect at power-up.
10.1.3 POL Setup Registers
Since the POL converters contain only RAM, the data defining performance parameters for each POL and Auxiliary
Device, such as the output voltage, protection thresholds, feedback loop compensation, turn-on and turn-off delays,
fault management settings, etc., is stored in the POL setup registers in the DPM. The POL setup registers consist of
23 data bytes and 2 CRC bytes. The Auxiliary Device setup registers occupy the same amount of bytes as a POL
converter, but only 3 registers have meaningful data. The other registers should be filled with 0x00. The POL setup
registers are listed in Table 2. Register significance is different in some cases between the new DP and older ZY series
POLs which are still supported. Differences are in bold for the DP series devices.
