KIT34704AEPEVBE - Using Hardware
The KIT34704AEPEVBE operates with a single power supply from 2.7 to 5.5V and is
controlled via I
2
C with the help of an USB-I
2
C bridge. Applying Input power supply will
start up the VG regulator, set switching frequency and soft start and finally turn on
REG2, REG3 and REG4 in stand alone mode, all other features can only be controlled
