SYNTHETIC RIPPLE REGULATOR |
摘要 |
A synthetic ripple regulator for a DC-DC converter generates an auxiliary voltage waveform that effectively replicates the waveform ripple current through an output inductor, and uses the auxiliary voltage waveform to control toggling of a hysteretic comparator. In a non-limiting implementation, a transconductance amplifier monitors the voltage across the inductor, and supplies an inductor voltage-representative current to a ripple waveform capacitor, so as to produce the auxiliary voltage waveform. Using the replicated inductor current for ripple regulation results in low output ripple, input voltage feed forward, and simplified compensation.
