PRODUCTION DATA
In this example, the ADRSEL pin is left floating. This sets the PMBus loop follower address to the EEPROM value, 0x24h (36d) by default, and the SYNC pin to auto detect with 0 degrees phase shift. Use Table 6-14 and Table 6-15 to select the resistor to AGND code and resistor divider code needed for the desired configuration.
If through pinstrapping, the desired address is not possible with the SYNC pin set to auto detect and synchronization is not needed in the application, the SYNC pin should be configured for SYNC_OUT. The device still regulates normally with the SYNC pin configured for SYNC_IN, however, if there is not clock input to the SYNC pin, the device declares a SYNC fault in the STATUS_MFR_SPECIFIC command.
