... Don’t care Send Byte Protocol The Send Byte protocol used on the LTC1663 is actually a subset of the Write Word protocol described previously. The Send Byte protocol can only be used to send the command byte information to the LTC1663 Start Condition Write Bit Acknowledge Stop Condition The Send Byte protocol is also used whenever the Write Word protocol is interrupted for any reason ...

... For example, a 0.1 F load can be driven by the LTC1663 if a 110 series resistance is used. The phase margin of the resulting circuit is 45 and increases mono- tonically from this point if larger values of resistance, ca- pacitance or both are substituted for the values given ...
