The High−Voltage Driver
The driver features a traditional bootstrap circuitry,
requiring an external high−voltage diode for the capacitor
refueling path. Figure 49 shows the internal architecture of
the high−voltage section.

The device incorporates an upper UVLO circuitry that
makes sure enough V
gs
is available for the upper side
MOSFET. The B and A outputs are delivered by the internal
logic, as Figure 43 testifies. A delay is inserted in the lower
rail to ensure good matching between these propagating
signals.
As stated in the maximum rating section, the floating
portion can go up to 600 VDC and makes the IC perfectly
suitable for offline applications featuring a 400 V PFC
front−end stage.
