Note 35: A current sink is provided by the BComp output while BOut is disabled:

Note 36: Internal reference related to VRefO. The same values to be found on pin BRegIn, while regulation loop is

stabilized.

Note 37: 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.

Note 38: tinh is about 300ns regardless of the H frequency
