The Input Low-side pins ILx (see Fig. 3) trigger the charge pump. As soon as the first exter-
nal low-side Mosfet is switched on and the corresponding bootstrap capacitor is connected
to GND, the CCP is pushed to high and provides about 13V at the CH pin. CCP can now di-
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 CCP 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.
