Abstract
Apparatus and method for a polarity independent step-up converter capable of operating with ultra low input voltage. The step-up converter as disclosed herein receives an input source having a variable polarity and includes a first core circuit coupled to the input source and an output of the step-up converter and a second core circuit coupled to the input source and the output of the step-up converter. The first core circuit is configured to be active for a first input voltage polarity to output a first step-up voltage and the second core circuit is configured to be active for a second input voltage polarity to output a second step-up voltage.
