摘要： The apparatus of the present invention has an interface circuit which returns power in H-level output state, a first power circuit supplying a first supply voltage, and a second power circuit supplying a second supply voltage. The second power circuit receives the entered first supply voltage from the first power circuit, and in a first operation mode (L-level output condition), brings the first supply voltage of 3.3 V down to the second supply voltage of 1.5 V and supplies same to the interface circuit. In a second operation mode (H-level output condition) of the load circuit, a current output from the load circuit is brought up to the first supply voltage of 3.3 V and feeds same back to the first power circuit.

摘要： The DC output of a power conversion unit is controlled based on a pulse signal generated by a PWM unit. An operations unit detects an output current Iout, and determines the operation mode of a load based on the detected current value. When the output current Iout is weak, a value smaller than usual is written to a cycle register. The PWM unit generates a pulse signal according to the data stored in the cycle register and an on-time register.

摘要： A reference voltage register stores a reference value Vref indicating the output voltage Vout of a power supply circuit. A digital filter amplifies the difference between the output voltage Vout from the power supply circuit and the reference value Vref stored in the reference voltage register. A pulse width computation unit computes the duty such that the output voltage Vout matches the reference value Vref, and generates the on-time of a pulse signal corresponding to the duty. A reference value operation unit updates the reference voltage register depending on the output current from the power supply circuit or the temperature around the power supply circuit.
