Abstract
A power converter includes a first switch and a second switch connected in series between an input power source and ground, an inductor connected between a common node of the first switch and the second switch, and an output capacitor and a pulse width modulation (PWM) generator configured to generate a gate drive signal for the first switch, wherein a leading edge of the gate drive signal is determined by a comparison result between a reference and a voltage proportional to an output voltage of the power converter and a trailing edge of the gate drive signal is determined by a comparison result between a voltage ramp and a variable voltage source.
