Abstract
Methods and apparatus for a DC-DC converter having input voltage feedforward for reducing the effects of input voltage signal transients. In embodiments, a feedback circuit receives an output voltage and generates a feedback signal and a modulation circuit receives the feedback signal and generates a control signal for a switching element configured to generate the output voltage, which is boosted from an input voltage. A feedforward module combines the input voltage and current information for an inductive energy storage element, which forms a boost circuit for generating the output voltage, and provides a feedforward signal to the modulation circuit. The modulation circuit can generate the control signal from a ramp signal and the feedforward signal.
