rectly feed the low-side output stages and recharge the bootstrap capacitors connected to
GND.
As soon as the first of the 3 external low-side Mosfets is switched off, the C
CP
will be pulled
down to be re-charged.
This synchronous operation with the output stages has the benefit that the electromagnetic
emissions generated by the charge pump can be filtered by the same filter necessary to filter
the EME of the converter itself. At the same time it is assured that the high voltage at the CH
pin is available just in time to charge the high-side bootstrap.
