effectively turned-on and the regulation can be lost. Thanks to the “bootstrap anti-
discharging system” the bootstrap cap is always kept charged. The following picture shows
the behaviour of the device in the following conditions: 12 V -> 3.3 V@0 A.
It can be observed that between two pulses trains the low-side is turned-on in order to keep
the bootstrap cap charged.
