Abstract
When the disclosed switching power supply is lightly loaded, efficiency is improved by lowering the switching frequency of a switching element. When its load is heavy, ripple noise of the output voltage is reduced by heightening the switching frequency of the switching element, and transient response is improved. The switching power-supply employs an RCC method and also includes an oscillation frequency inhibit circuit for inhibiting an oscillation frequency, and an operation switching circuit for starting or stopping the operation of the oscillation frequency inhibit circuit. By applying a signal voltage to the operation switching circuit, the operation of the oscillation frequency inhibit circuit is turned on while a load is light and turned off while a load is heavy, and a normal RCC oscillation operation is performed.
