Classification: CPC H  Y | IPC H

Claim 7:
8. An electronic device, comprising:
a voltage converter circuit having:
a converter input and a converter output, wherein the converter input has a voltage VIN, and the converter output has a voltage VOUT;
a high-side switch;
a low-side switch; and
a comparator having first and second comparator inputs, a bias input, and a comparator output, wherein first comparator input is coupled to a feedback voltage terminal providing a signal proportional to VOUT, and the second comparator input is coupled to a reference voltage terminal;
a bias current source coupled to the bias input and configured to provide a bias current; and
a dynamic biasing circuit coupled to the bias input and including a current mirror, wherein the dynamic biasing circuit is configured to provide a supplemental bias current, the supplemental bias current equal to K*(VIN−VOUT);

a battery coupled to the converter input; and
a load coupled to the converter output.
