摘要： A pulse control system for a multiphase regulator including an error amplifier, a multiphase generator, and an adaptive controller. The error amplifier provides an error signal indicative of output voltage error. The multiphase generator develops modulation pulses for phases based on the error signal. The adaptive controller is responsive to a load indication signal and redirects at least one modulation pulse from a first of phase to a second phase. The load indication signal may be received from a microprocessor indicating a low power mode. The adaptive controller provides a smooth and efficient transition to low load conditions by dropping operation of one or more phases and redirecting modulation pulses to the remaining one or more phases, and reduced phases improve power efficiency for the low load conditions.
