Problems solved by technology

[0003] However, traditional switching regulators tend to generate high peak currents during operation, for example, during start-up, and different switching regulators produce different peak currents. For different switching regulators The operation of recording and adjusting the peak current is cumbersome

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the drawings and embodiments.

[0026] In a preferred embodiment, such as figure 1 As shown, a power supply system with self-learning function is proposed, which may include:

[0027] A pulse width modulation driver 10, including a control input terminal, a first pulse output terminal and a second pulse output terminal;

[0028] The pulse width modulation driver 10 receives a control signal Vcomp through the control input terminal, and outputs the first pulse signal PWM1 from the first pulse output terminal and the second pulse signal PWM2 from the second pulse output terminal according to the control signal Vcomp;

[0029] A PMOS tube PM1, the gate of the PMOS tube PM1 is connected to the first pulse output terminal;

[0030] An NMOS tube NM1, the gate of the NMOS tube NM1 is connected to the second pulse output terminal;

[0031] The drain of the NMOS tube NM1 is connected to the source of the PMOS tube P...

Abstract

The present invention relates to the technical field of power electronics, in particular to a power supply system with a self-learning function comprising: a pulse width modulation driver; a PMOS tube; an NMOS tube; a fuse, including a plurality of parallel fuses and a soft start unit , each fuse has a different current upper limit from low to high, and each fuse is connected to the output node; the soft start unit connects each fuse to one end not connected to the output node, so as to pass through all fuses The total current of the wire generates and outputs a reference signal; a first comparator; a current limiting protection circuit; it can automatically record and adjust the peak current of electrical signals output by different power supply systems, and has simple operation and high reliability.

Description

Technical field [0001] The present invention relates to the field of power electronics technology, in particular to a power supply system with a self-learning function. Background technique [0002] With the rapid development of microelectronics technology, step-down switching regulators are widely used in step-down applications due to their simple circuit structure, convenient adjustment, and high reliability. According to different control mechanisms, step-down switching regulators The advantages of working methods, improving the conversion efficiency of converters, are increasingly applied to switching power supplies. [0003] However, traditional switching regulators are prone to generate higher peak currents during operation, such as during startup, and the peak currents generated by different switching regulators are different. For different switching regulators The operation of recording and adjusting the peak current is cumbersome. Summary of the invention [0004] To solv...
