Abstract
Exemplary embodiments are directed to a power controller. A method may include comparing a summation voltage comprising a sum of an amplified error voltage and a reference voltage with an estimated voltage to generate a comparator output signal. The method may also include generating a gate drive signal from the comparator output signal and filtering a signal coupled to a power stage to generate the estimated voltage.
