Latest Patents

Kawakubo's latest patents include a digital control switching power-supply device and information processing equipment. This invention aims to provide a digital control switching power-supply device capable of achieving fast transient response during sudden load changes. The device incorporates normal digital signal processing means that outputs a PWM pulse signal with a desired duty. Additionally, it features transient variation detection means, composed of a CR filter across an output inductor and a window comparator, to prepare for sudden load changes. If a sudden decrease in load is detected, the device outputs a PWM pulse signal with a duty of 0%. Conversely, if a sudden increase in load is detected, it outputs a PWM pulse signal with a duty of 100%.
