Abstract

The invention relates to a control circuit of a voltage-type regulator and a control method of the same. According to the control method of the voltage-type regulator, feedback signals of represented output voltage and ripple wave signals which are the same with a duty ratio in phase position are overlaid mutually, so that first voltage signals are generated; through comparison between the first voltage signals and an upper limit reference voltage and comparison between the first voltage signals and a lower limit reference voltage, corresponding comparison signals are generated; under a first working condition, an on-off state of a main power switch tube of the voltage-type regulator is controlled by constant time signals; and under a second working condition, theon-off state of the main power switch tube is controlled by the comparison signals.

Description

technical field [0001] The invention relates to the field of switching power supplies, and more specifically, relates to a control circuit and a control method of a voltage-type regulator in a constant-time control mode capable of self-adaptive adjustment. Background technique [0002] Voltage regulators, such as DC-DC voltage converters, are used to provide stable voltage sources for various types of electronic equipment. High-efficiency DC-DC converters are especially required for battery management of some low-power devices (such as laptop computers, portable mobile phones, etc.). The switching voltage regulator converts the input voltage into a high-frequency voltage signal, and then filters the high-frequency input voltage signal to generate a DC output voltage. A voltage-mode regulator usually includes a switch that alternately couples and decouples an input DC voltage source (such as a battery) to a load (such as an integrated circuit); an output filter device, usual...
