Figure 30. The Internal High ? Voltage Section of the NCP1393
The A and B outputs are delivered by the internal logic, as
depicted in block diagram. This logic is constructed in such
a way that the M lower driver starts to pulse firs after any
driver restart. The bootstrap capacitor is thus charged during
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.
