Oscillator

The internal oscillator is a current-controlled oscillator that

generates a sawtooth output. The frequency of the

the currents flowing into the IFS and IRS pins.

The minimum frequency and the dead time are set by the

frequency is exactly twice the bridge frequency to achieve

an accurate 50% duty factor. An overview of the oscillator

and driver signals is given in Fig.6.
