An apparatus for and method of achieving current balancing among phases of a multi-phase power supply by reducing and controlling the temperature variation among packages disposed within each phase. Each package contains a dc-to-dc converter (e.g. a buck converter), a temperature sensor and may also contain a driver, which supplies a pulse train for driving the converter. By controlling the temperature among phases to within ±X % a balancing of currents among phases to within ±X/2% is achieved.
