Oscillator
The internal oscillator is a current-controlled oscillator that
generates a sawtooth output. The frequency of the
sawtooth is determined by the external capacitor Cf and
the currents flowing into the IFS and IRS pins.
The minimum frequency and the dead time are set by the
capacitor Cf and resistors Rf(min) and Rdt. The maximum
frequency is set by resistor Rf (see Fig.10). The oscillator
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.
