ABSTRACT:
An integrated circuit having a bootstrap charger for using in a switching mode power supply is disclosed. In one embodiment, a capacitor is connected between a floating terminal and a bootstrap supply terminal with a voltage drop over the capacitor, a comparing device with a first input terminal receiving a fraction of the voltage drop, a second input terminal receiving a reference, and an output terminal providing a control signal, and a charge circuit configured to charge the capacitor dependent on the control signal.
