Abstract
A switch-type regulator with a soft-start function having an output terminal supplying an output voltage, and including an error amplifier, having a first input receiving a constant reference voltage, a second input receiving a feedback voltage dependent on the output voltage, and supplying a compensation terminal with an error voltage correlated to the difference between the reference voltage and the feedback voltage. The error amplifier includes a differential amplifier. The regulator also includes a compensation network connected to the compensation terminal. A soft-start function is obtained exploiting the compensation network.
