Abstract
A boost converter circuit that includes a power supply, an inductor coupled to the power supply to receive current from the power supply, a diode coupled to receive current from the inductor and coupled to provide current to a load as an output, an inductor switch coupled to a node between the inductor and the diode for selectively switching current from the inductor anyway from the diode, and a ramp circuit. The ramp circuit is coupled to the node between the inductor and the diode, and is configured to selectively sample a voltage at the node between the inductor and the diode via a sampling switch and use the sampled signal to produce a stabilization ramp to stabilize the output.
