Abstract

The invention provides a flyback power supply system. The system comprises a transformer, and a control chip which comprises a first detection circuit and a second detection circuit. One end of an auxiliary winding of the transformer is directly grounded; the other end of the auxiliary winding is grounded through a voltage division circuit; the first detection circuit and the second detection circuit are connected to the same pin of the control chip, and are connected to a wiring end between voltage dividing resistors in the voltage dividing circuit through the pin and a thermistor, and the first detection circuit and the second detection circuit alternately carry out overvoltage protection detection and over-temperature protection detection within the demagnetization time of the transformer.

Description

[0001] Division description [0002] This application is a divisional application of the invention patent application entitled "Flyback Power Supply System" with the application date of April 08, 2016 and the application number of 201610218548.2. Technical field [0003] The present invention relates to the field of circuits, and more specifically to a flyback power supply system. Background technique [0004] Generally, the flyback power system isolates the primary side input and the secondary side output through a transformer, and feeds back the output voltage information to the control chip located on the primary side through an optocoupler, and through the different pins of the control chip and the control chip. The overvoltage / undervoltage protection (OVP / UVP) detection circuit and the overtemperature protection (OTP) detection circuit are connected to trigger overvoltage / undervoltage protection and overtemperature protection. [0005] figure 1 It is the circuit schematic diagr...
