MULTIPHASE POWER CONTROLLER WITH DYNAMIC PHASE MANAGEMENT

In described examples, a multiphase power controller generates a set of switching control signals (160) to drive a set of power stages (150). The set of power stages (150) generates an output (VOUT) that drives a load. The multiphase power controller includes a summer (120) to generate an equivalent voltage (122) representative of a sum of inductor currents from each of an inductor in the set of power stages (150). A threshold generation circuit (110) generates a set of threshold signals (123) in response to a set of control outputs (130) and a reference (REF). A set of comparators (125) generates the set of control outputs (130), in response to the equivalent voltage (122) and the set of threshold signals (123). A state machine (135) generates a set of phase control signals (140) in response to the set of control outputs (130). The set of control outputs (130) changes a number of the set of switching control signals (160). 在所描述的示例中，多相位功率控制器生成开关控制信号(160)组以驱动功率级(150)组。功率级(150)组生成驱动负载的输出(V)。多相位功率控制器包括求和器(120)以生
