In the 1950s, NASA developed a switching power supply for rockets with the goal of miniaturization and light weight. In the development process of more than half a century, switching power supply has gradually replaced the continuous working linear power supply designed and manufactured by traditional technology due to its small size, light weight, high efficiency, low heat generation and stable performance. In electronic and electrical equipment. In the 1980s, the computer fully realized the switching power supply, and took the lead in completing the power conversion of the computer. In the 1990s, switching power supplies were widely used in the fields of electronics, electrical equipment, and home appliances, and switching power supply technology entered a period of rapid development.
Cadence's PSpice is a circuit simulation software that simulates complex analog-to-digital hybrid circuits, and switching power supplies are no exception.
The appendix is ​​the application circuit, see the PDF document for more details!
Function description
The socket is ordinary converter,with two output 5V2A power USB power supply at the same time,can be very convenient in use electrical appliances and recharge the equipment at the same time,such as digital products like Iphone Ipad,MP3,MP4 etc.The charge apply to full range of international AC output,no-load power consumption less than 0.3W,with short circuit,overload,over-voltage protection,can be convenient for your life and save more energy
Timer Control Time Adgustment
1.Press the power switch 1 time,the 1HOUR LED will light on.The Timer into ON mode,USB and control socket output ON .
2.Continuously press the power switch the LED light on,the Countdown mode and LED light on will cycle change from 1HR,2HR,4HR,6HR,8HR,10HR.
