摘要

An electrical circuit and method of power management of a cellular telephone includes a battery adapted to produce a battery voltage; a LDO regulator operatively connected to the battery and adapted to provide a constant supply voltage from the battery voltage; and a DC-DC converter operatively connected to the LDO regulator, wherein the DC-DC converter is adapted to step down the constant supply voltage to a lower voltage level, wherein the LDO regulator and the DC-DC converter are embedded on a single integrated circuit chip. The constant supply voltage equals 3.6V at an output of the LDO, and the constant supply voltage is applied to an input of the DC-DC converter. Moreover, the battery voltage equals at most 5.5V.
