L6919E
Two main configurations can be distinguished: Single Supply (VCC=VIN=12V) and Double Supply (VCC=12V
VIN=5V or different).
– Single Supply: In this case JP6 has to be completely shorted. The device is supplied with the same rail
that is used for the conversion. With an additional zener diode DZ1 a lower voltage can be derived to
supply the mosfets driver if Logic level mosfet are used. In this case JP1 must be left open so that the
HS driver is supplied with V
IN
-V
DZ1
through BOOTx and JP2 must be shorted to the left to use V
IN
or to
the right to use V
IN
-V
DZ1
to supply the LS driver through VCCDR pin. Otherwise, JP1 must be shorted
and JP2 can be freely shorted in one of the two positions.
– Double Supply: In this case VCC supply directly the controller (12V) while V
IN
supplies the HS drains
for the power conversion. This last one can start indifferently from the 5V bus (Typ.) or from other buses
allowing maximum flexibility in the power conversion. Supply for the mosfet driver can be programmed
through the jumpers JP1, JP2 and JP6 as previously illustrated. JP6 selects now V
CC
or V
IN
depending
on the requirements.
Some examples are reported in the following Figures 21 and 22.
