Abstract
An apparatus includes a first adjustable-gain conversion unit configured to receive a ramp signal, a second adjustable-gain conversion unit configured to receive a feedback signal proportional to an output voltage of a power converter, a third adjustable-gain conversion unit configured to receive an output signal of an error amplifier and a comparator configured to determine a turn-on of a high-side switch of the power converter based on outputs of the first adjustable-gain conversion unit, the second adjustable-gain conversion unit and the third adjustable-gain conversion unit.
