6.8 - DC/DC CONTROLLER SECTION
VCC = 12V, Tamb = 25°C
Note 41: A current sink is provided by the BComp output while BOut is disabled:
Note 42: Internal reference related to VRefO. The same values to be found on pin BRegIn, while regulation loop is
stabilized.
Note 43: Only applies to configuration specified in "Test conditions" column, i.e. synchronization of BOut “Off-to-On”
edge with horizontal flyback signal. Refer to chapter "DC/DC controller" for more details.
