1. An apparatus configured according to a transformer based step down topology, comprising:
a first transformer configured to transfer energy of an input source from a primary side of the first transformer to a secondary side of the first transformer for driving a load at the secondary side;
a first inductor and a second inductor electrically coupled at the secondary side;
an inductor connected between the second inductor and a ground; and
a primary side directional conducting element and a secondary side directional conducting element configured to perform a first phase of transferring the energy through the first inductor and a second phase of transferring the energy through the second inductor, wherein the first inductor induces the second inductor to transfer energy during the first phase and the second inductor induces the first inductor to transfer energy during the second phase.
