Abstract

An electronic device (20), such as a radiotelephone, is connectable to a variable-level power source (22). The electronic device (20) includes a rechargeable power source (70) as a portion thereof. Power source control signals (28) are generated for application to the variable-level power source (22) indicative of voltage levels of the rechargeable power supply (70). The voltage levels of the operative power generated by the variable-level power source (22) is caused to be of levels responsive to measured levels of the voltage of the rechargeable power supply (70). The voltage levels of the operative power of the variable-level power source (22) thereby track the voltage levels of the rechargeable power supply (70). <IMAGE>
