Questions answered in these manuals
What is the input voltage range for this power system manager?
The device accepts an input voltage ranging from 4.5V to 24V.
How much output current can each phase deliver?
Each phase is capable of delivering up to 30A of output current.
Are repeated starts supported by all I2C controllers?
No, repeated starts are not supported by all I2C controllers but are required for PMBus/SMBus reads.
From: Linear Technology LTC3880 Dual Output PolyPhase Step-Down DC/DC Controller Application Note 135
What is the byte order endianness for PMBus?
The data ordering specifies that the most significant bit of the least significant byte is always sent first, making it little-endian.
