Title: Atsuo Fukui: Innovator in Voltage Regulation Technology

Introduction

Atsuo Fukui is a prominent inventor based in Chiba, Japan. He has made significant contributions to the field of electrical engineering, particularly in voltage regulation technology. With a total of 10 patents to his name, Fukui has demonstrated a commitment to innovation and excellence in his work.

Latest Patents

Fukui's latest patents include a current mode step-down switching regulator and a voltage regulator. The current mode step-down switching regulator enhances over-current limiting characteristics even when the function operates to reduce output voltage. This innovative design includes a pulse adjusting circuit that thins out the switching output signal when an over-current is detected, thereby reducing the influence of response delay in the over-current detecting comparator. The voltage regulator he developed operates effectively even when the input power source voltage and output voltage are small. It features a reference voltage source, a voltage dividing circuit, and an overcurrent limiting circuit that controls a first transistor in response to an error amplifier's output.
