摘要： A converter employs a comparator sensing the current through an output diode, for generating a confirmation signal of an OFF state of the switch until the discharge current of the inductor toward the user circuit and the external filter capacitance has become null, thus ensuring the operation in a discontinuous mode under any condition. A turn-off signal of the switch is provided by another comparator which, instead of the voltage on a sensing resistance connected in series with the switch, may sense the voltage across the switch itself. This latter embodiment is particularly suited in case of an output MOS transistor and the circuit comprises means for masking for a preset period of time the turn-off signal produced by said comparator, in order to allow a predefined turn-on phase of the switch. Enabling of the turn-on of the switch is conventionally provided by a dedicated (third) comparator of the output voltage. The circuit does not require the use of an error amplifier, for the compensation of which special complex integratable circuits or alternatively access to the output node of the error amplifier through a dedicated pin may be needed. Neither a local oscillator for turning off the switch is needed. The circuit is simple and suited for integration in large complex system chips, where there is a limited availability of pins and silicon area. Different embodiments are described.
