Abstract
An integrated circuit can comprise an output terminal, a power transistor having a first current electrode coupled to the output terminal and a second current electrode coupled to a power supply terminal, a driver having an output coupled to a control electrode of the power switch, a capacitor having a first terminal coupled to the output terminal and a second terminal coupled to a circuit node, a first low pass filter coupled between the circuit node and an input of the driver, the first low pass filter having a first cut off frequency, a set of current sources, and a second low pass filter coupled between the circuit node and an output of the set of current sources. The second low pass filter can have a second cut off frequency that is higher than the first cut off frequency.
