... NXP Semiconductors 7.2 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 C flowing into the IFS and IRS pins. The minimum frequency and the non-overlap time are set by the capacitor C resistors R The oscillator frequency is exactly twice the bridge frequency to achieve an accurate 50 % duty factor ...

NXP Semiconductors The R f(min) charge current (rising slope) of the C frequency is defined by this minimum charge current ( IRS1 t = IRS1 f osc min f bridge min 7.5 Maximum frequency resistor The output voltage is regulated by changing the frequency of the half-bridge converter. The maximum frequency is determined by the R the error amplifi ...

... NXP Semiconductors Bridge frequency accuracy is optimum in the low frequency region. At higher frequencies both the non-overlap time and the oscillator frequency show a decay. The frequency of the oscillator depends on the value of capacitor C voltage swing V frequencies the accuracy decreases due to delays in the circuit. Fig 6. ...

... NXP Semiconductors At start-up the soft start capacitor is charged to V about the maximum frequency. After start-up the external soft start capacitor is discharged by I place via R frequency sweep rate. When the circuit comes into regulation, the error amplifier output controls the VCO pin voltage and the CSS voltage sweeps down further to zero volt ...
