Description

technical field [0001] The invention relates to the technical field of switching power supplies, in particular to a remote monitoring switching power supply circuit system. Background technique [0002] Switching power supply is a kind of power supply that uses modern power electronic technology to control the time ratio of switching on and off to maintain a stable output voltage. Switching power supply is generally composed of pulse width modulation (PWM) control IC and MOSFET. With the development and innovation of power electronics technology, switching power supply technology is constantly innovating. At present, switching power supply is widely used in almost all electronic devices due to its small size, light weight and high efficiency. It is an indispensable power supply method for the rapid development of today's electronic information industry. Some existing switching power supplies have a single function, and there are many deficiencies in energy saving and safety...
