Abstract
Apparatus and associated methods relate to circuit load balancing in a multi-phase power supply system (MPPSS). In an illustrative example, a MPPSS may include multiple power phases, each driven by a corresponding power phase driver (e.g., a DRMOS). A controller, for example, may include multiple current balancing inputs, each corresponding to one of the power phases. For example, the current balancing inputs may be generated by a dual mode current sensing circuit (DMCSC). For example, in a data collection mode of a power phase, the DMCSC may store information of an output current. In a sensing mode of the power phase, the DMCSC may generate a current balancing input to the controller based on a direct current resistance of the current sensing circuit and an active resistance in the low side driver circuit. Various embodiments may advantageously measure current imbalance in a cost effective manner.
