    • PROBLEM TO BE SOLVED: To place an emphasis on cost efficiency and performance efficiency of a boost converter circuit.SOLUTION: A boost converter circuit 100 includes: a power supply 110; an inductor 120 coupled to the power supply 110 to receive current from the power supply 110; a diode 130 coupled to receive current from the inductor 120 and coupled to provide current to a load 160 as an output; an inductor switch 140 coupled to a node between the inductor 120 and the diode 130 for selectively switching current from the inductor 120 from the diode 130; a ramp circuit 105. The ramp circuit is coupled to the node between the inductor 120 and the diode 130, and is configured to selectively sample a voltage at the node between the inductor 120 and the diode 130 by a sampling switch and use the sampled signal to produce a stabilization ramp to stabilize the output.
