发明名称 SWITCHING REGULATOR SLOPE COMPENSATION GENERATOR CIRCUIT
摘要 A slope compensation circuit that provides slope compensation in a switching regulator is provided. The slope compensation circuit preferably is adapted to receive an oscillator pulse train from a pulse width modulator oscillator and a modulator pulse train from a pulse width modulator. The circuit preferably includes a feedback loop that is responsive to the oscillator pulse train. The circuit preferably provides a slope compensation pulse train of ON and OFF states that is responsive in part to the feedback loop and in part to the pulse width modulator switch pulse train. The invention preferably achieves lower maximum slope compensation current by incorporating an analog feedback loop in the PWM system to start slope compensation preferably only slightly ahead of PWM switch-OFF. This preferably occurs independent of the PWM duty cycle.
