1. A multiple output synchronous power converter comprising:
a control circuitry; an inductance element having a primary side and a secondary side; a switching circuit, said inductance element arranged, responsive to said switching circuit, to receive power at said primary side from a power source, and said inductance element further arranged, responsive to said received power at said primary side, to output at said secondary side a function of said received power; a first output non-switchably coupled to said secondary side of said inductance element, said control circuitry arranged to switch said switching circuit so as to maintain said first output at a predetermined level; a second output, different than said first output, arranged to receive electrical energy from said secondary side of said inductance element; and a first electronically controlled switch, said first electronically controlled switch arranged to be alternately in a closed state and an open state, responsive to said control circuitry, wherein responsive to said first electronically controlled switch being in a first of said closed state and said open state, said second output is arranged to receive a first portion of said power output from said secondary side of said inductance element, wherein responsive to said first electronically controlled switch being in a second of said closed state and said open state, said second output is arranged to not receive said first portion of power, wherein said control circuitry is arranged to alternately set said first electronically controlled switch in one of said first and second of said closed state and said open state in synchronization with said switching of said switching circuit, and wherein the amount of time said first portion of power is received by said second output is less than the amount of time said function of power is output at said secondary side of said inductance element. |
