Switching Circuit

Abstract

A multiple output switching circuit (300) comprising an input (302) configured to receive power from a power source; a first output (304) configured to provide a first output voltage; and an inductor (308) and a power switch (306) connected between the input (302) and first output (304). The power switch (306) is operable to transfer power from the input (302) to the first output (304). The switching circuit further comprising a second output (312) configured to provide a second output voltage; a second switch (310) coupled between the first output (302) and the second output (312); and a second switch controller (314) configured to provide the second switch (310) with a second switch control signal (318) such that power is transferred from the input (302) to the second output (312) when the first output voltage level reaches a first output threshold level.
