Abstract

See full text

An apparatus, method and article of manufacture are disclosed which provides for auxiliary battery conservation in adapters requiring auxiliary batteries. A power controller selects from one of two or more power sources to provide variable power components with DC power. For instance, power consumption of the transmitter (more specifically the transmit power amplifier) varies with the desired transmit power level. The transmitter can be supplied with DC power from the host device or the auxiliary source or both. The power controller can select the source of DC power (i.e., the host device or the auxiliary battery) or may combine the two power sources to provide necessary power to the transmit power amplifier.
