ABSTRACT:
A switching regulator with its less ripples, less switching loss, and low noise, which is capable of being miniaturized with high efficiency is provided. PWM control signals outputted from a terminal T6 of a pulse width control circuit IC1 are inputted to delay circuits DLa and DLb, respectively. The PWM control signal inputted to the delay circuit DLa, only a rise of which is delayed by a resistor Ra and a capacitor Ca, is applied to a gate of FET Q2 via a wave shaping circuit IC2. On the other hand, the PWM control signal inputted to a delay circuit DLb, only a fall of which is delayed by the resistor Rb and the capacitor Cb, is inverted via a wave shaping circuit IC2 and is applied to a gate of FET Q1 as an inverted control signal. Therefore, FETs Q1 and Q2 are turned ON/OFF in a predetermined period, and a pause period where FETs Q1 and Q2 are turned OFF is only a delayed constant period.
