    • Miniaturization of a multiphase type power supply device can be achieved. A power supply control unit in which, for example, a microcontroller unit, a memory unit and an analog controller unit are formed over a single chip, a plurality of PWM-equipped drive units, and a plurality of inductors configure a multiphase power supply. The microcontroller unit outputs clock signals each having a frequency and a phase defined based on a program on the memory unit to the respective PWM-equipped drive units. The analog controller unit detects a difference between a voltage value of a load and a target voltage value acquired via a serial interface and outputs an error amp signal therefrom. Each of the PWM-equipped drive units drives each inductor by a peak current control system using the clock signal and the error amp signal.
    • 可以实现多相电源装置的小型化。 电源控制单元,其中例如在单个芯片上形成微控制器单元,存储单元和模拟控制器单元,多个配备PWM的驱动单元和多个电感器构成多相电源。 微控制器单元输出每个具有基于存储器单元上的程序定义的频率和相位到相应的配备有PWM的驱动单元的时钟信号。 模拟控制器单元检测负载的电压值与通过串行接口获取的目标电压值之间的差值,并输出误差放大器信号。 每个配备PWM的驱动单元通过使用时钟信号和误差放大器信号的峰值电流控制系统驱动每个电感器。
