The invention provides a battery charger comprising a power input for receiving a power supply for charging a battery; an integrated circuit, operating at a voltage, supplying on-chip functions for battery charger operation coupled to said power input and adapted to communicate with said battery. The integrated circuit comprises a voltage input, Vchg, coupled to a charge controller and/or a charger circuit; and a voltage regulator interposed between the voltage input, Vchg, and said charge controller and/or charger circuit, such that the voltage regulator regulates the voltage at the voltage input, Vchg, to supply a regulated voltage, Vreg, load to be compatible with the integrated circuit voltage operation.
