Digital Power-Supply Controller/Monitor
with PMBus Interface
Table 1. EEPROM Contents
Note 8: For a 2-byte value, the most significant byte is written first (lower offset) and then the least significant byte is written last
Note 9: To store temperature values to the EEPROM, add 3010 (decimal) to the PMBus value.
Note 10: To store voltage values to the EEPROM, no conversion is needed in 2V mode. For 5.5V mode value, divide the PMBus value by 2.75.
Note 11: To store current values to the EEPROM, multiply the PMBus value by IOUT_SCALE and divide by 37.24.
