Patent ID: 8143748

Claim:
A power supply, comprising: a switching controller module, operable to generate a load switching signal and an auxiliary switching signal, wherein: the load switching signal comprises pulses, each pulse of the load switching signal having a pulse width defining a charging duration, a first portion of the charging duration being defined as a function of an operational load power and a second portion of the charging duration being defined as a function of an operational auxiliary power; and the auxiliary switching signal comprises pulses, each pulse of the auxiliary switching signal having a pulse width defined by the second portion of the charging duration; a load power module, communicatively coupled with the switching controller module, and operable to generate output load power as a function of an input power signal and the load switching signal, such that the output load power is generated during the first portion of the charging duration; and an auxiliary power module, communicatively coupled with the switching controller module, and operable to generate output auxiliary power as a function of the input power signal, the load switching signal, and the auxiliary switching signal, such that the output auxiliary power is generated during the second portion of the charging duration.
