ABSTRACT:
In a circuit, a high side driver control circuit outputs gating signals to a high side driver of a synchronous converter responsive to a pulse width modulated input signal. A synchronous rectifier driver circuit outputs a gating signal to a synchronous rectifier of the synchronous converter responsive to the pulse width modulated input signal. An inhibit circuit inhibits the gating signal to the synchronous rectifier upon detection of a zero crossing condition. A circuit detects the zero crossing condition respective to comparing a measured value to a nominal value adjusted by a delta value. A duty cycle observer circuit determines the average duty cycle of the pulse width modulated input signal and varies the reference value.
