PRODUCTION DATA.
The VIN_ON command sets the value of the input voltage, in Volts, at which the unit should start power conversion. This command has two data bytes encoded in linear data format, and must be accessed through Read Word/Write Word transactions. The VIN_ON command is shared between Channel A and Channel B. All transactions to this command will affect both channels regardless of the PAGE command. The supported range for VIN_ON is from 4.0 V volts to 11.25 Volts.
